Description

BACKGROUND OF THE INVENTION

Field of the Invention

This invention relates to a thermal imaging device, a thermal image processing device, and infrared detection field and, more particularly, to a device and a method for analyzing thermal images.

Description of the Related Art

At present, a user is necessary to depend on subjective experience to manually set an analysis area of a specified part of a body thermal image, to acquire an analysis result of the thermal image. The analysis area corresponds to the specified part in an infrared thermal image to be analyzed, such as area units, i.e. points, lines, or planes, or a combination of the multiple area units. Even if the analysis area is preset, the use is still inconvenient. As the user fails to directly understand the position in the body thermal image where the analysis area should be according to an analysis area F1 in FIG. 6, when the next photographed body of the same type is photographed, the preset analysis area fails to correspond to a correct part of the body thermal image (such as, different sizes of the body thermal images or different positions of the body thermal images in an infrared thermal image), thereby causing the analysis result with great discrete and being difficult to perform effective diagnosis and determination subsequently.

The setting operation of the analysis area is complicated and is easy to make a mistake. For example, as numbers, types, positions, or sizes of area units S01, S02 of the analysis area F1 in FIG. 6 change, the final analysis result may be different. The manual setting operation (such as selecting the type of the analysis area, such as points, lines, or planes, and disposing at a corresponding position of the body thermal image) is very complicated. The analysis area may be set, depending on the understanding of the user for an analysis part of a photographed body. Different photographed bodies have the respective analysis part, which requires great skill. Due to the above reasons, the complicated analysis area is inconveniently set. At present, the user depends on experience to perform simple analysis operation, such as setting automatical capture of maximum temperature. However, the extensive analysis mode may reduce the reference value of the analysis result during photographing.

Further, the operation of setting the analysis mode corresponding to the analysis area is also complicated. The different settings of the analysis mode acquire different analysis results. The analysis mode is set, depending on the understanding of the user for the analysis parts, analysis methods, and diagnosing method of different photographed bodies, which requires great skill. The analysis mode represents an analysis computing rule used by acquiring the analysis result after specified analysis for the thermal imaging data determined by the analysis area, such as computing the maximum temperature, an average temperature, the minimum temperature, or a percentage content, and a computing relation between different area units, i.e. difference in temperature.

Therefore, a thermal imaging device capable of allowing the set analysis area to conveniently photograph the next photographed body of the same type and ensuring the photographing quality is needed, thus to reduce the setting operation of the users.

Further, the analysis area of the body thermal image to be specially analyzed may be set conveniently, and further the analysis mode corresponding to the analysis area may be set easily, thus to acquire the reliable analysis result via the analysis. Thereby, the common user can achieve the better infrared photographing level.

DETAILED DESCRIPTION OF THE INVENTION

This invention may be further described according to the drawings. For better understanding, the following described embodiments do not limit the scope of the invention and can be changed to different forms in the scope of the invention. In the invention, thermal imaging data may be thermal image AD value data (such as the data acquired after AD conversion of output signals of an infrared detector), image data of an infrared thermal image, array data of temperature values, or other data generated based on the thermal image AD value data. In the first embodiment, a thermal imaging device 13 is as an example of a device for analyzing thermal images.

The structure of the thermal imaging device 13 in the first embodiment is described according to FIG. 1. FIG. 1 is a block diagram showing the thermal imaging device 13 according to the embodiment.

The thermal imaging device 13 includes a photographing part 1, an image processing part 2, a display controlling part 3, a display part 4, a communication I/F 5, a temporary storage part 6, a storage card I/F 7, a storage card 8, a flash memory 9, a control part 10, and an operation part 11. The control part 10 is connected with each other part via a control and data bus 12, and is responsible for overall control of the thermal imaging device 13. A CPU, a MPU, a SOC, or a programmable FPGA may realize the control part 10.

The photographing part 1 includes an optical part, a lens driving part, an infrared detector, and a signal preprocessing circuit, which are not shown. The optical part is composed of infrared optical lenses, and is used for focusing received infrared radiation on the infrared detector. The lens driving part drives the lenses to perform focusing or zooming operation according to a control signal of the control part 10, and the optical part may also be manually regulated. The infrared detector, such as a refrigerating or non-refrigerated infrared focal plane detector, converts the infrared radiation passing through the optical part to electrical signals. The signal preprocessing circuit, including a sample circuit, an AD conversion circuit, and a timing trigger circuit, performs signal processing such as sampling for the electric signals output from the infrared detector in a specified period. The signals are converted to digital thermal imaging data by the AD conversion circuit. The thermal imaging data may be 14-bit or 16-bit binary data (also called AD value).

The image processing part 2 is used for performing specified processing for the thermal imaging data acquired by the photographing part 1. The image processing part 2 performs processing for converting data to be suitable for displaying or recording, such as modification, interpolation, pseudo-color, synthesis, compression, or decompression. The image processing part 2 is used for performing specified processing for the thermal imaging data acquired by the photographing part 1 to acquire image data of the infrared thermal image. For example, the imaging processing part 2 may perform specified processing such as non-uniformity correction or interpolation for the thermal imaging data acquired by the photographing part 1 and then may perform pseudo-color processing for the thermal imaging data after the specified processing, to acquire the image data of the infrared thermal image. In one embodiment of the pseudo-color processing, a corresponding range of a pseudo-color plate may be determined according to a range of the thermal imaging data (AD value) or a setting range of the AD values, and the particular color value to which the thermal imaging data corresponds in the range of the pseudo-color plate is used as the image data of the corresponding pixel position in the infrared thermal image. In the embodiment, gray scaling for the infrared image may be as a special example of the pseudo-color processing. Further, based on a record instruction of the control part 10, the image processing part 2 is used for performing specified compression for the thermal imaging data to acquire compressed thermal imaging data, and then the thermal imaging data is record to a storage medium such as the storage card 8. In addition, the image processing part 2 performs different processing related to image processing, such as increasing and decreasing pixels to change the dimension of the image data, or cutting of the image data. The image processing part 2 may be realized by a DSP, other microprocessors, or a programmable FPGA, or the image processing part 2 may also be integrally formed with the control part 10.

According to the control of the control part 10, the display controlling part 3 allows the display part 4 to display image data for displaying stored in the temporary storage part 6. In detail, the display controlling part 3 includes a VRAM, a VRAM control unit, and a signal generating unit. Based on the control of the control part 10, the signal generating unit reads image data, read from the temporary storage part 6 and stored in the VRAM, regularly from the VRAM, and generates video signals to be displayed on the display part 4. In the thermal imaging device 13, the display part 4 is as an example of a display part. However, the invention is not limited thereto. The display part may further be other display devices connected with the thermal imaging device 13, and the display controlling part 3 may be integrally formed with the image processing part 2 or the control part 10.

The communication I/F 5 may be an interface for connecting and exchanging data between the thermal imaging device 13 and an external device according to communication specification such as USB, 1394, or network. The external device may be a personal computer, a server, a PDA (personal digital assistant device), other thermal imaging devices, a visible light photographing device, or a storage device.

The temporary storage part 6, such as a RAM or DRAM volatile storage, is a buffer storage for temporarily storing the thermal imaging data output from the photographing part 1, and is a working storage of the image processing part 2 and the control part 10 for temporarily storing the processed data of the image processing part 2 and the control part 10. However, the invention is not limited. A storage or register in the processor such as the control part 10 or the image processing part 2 may also be defined as a temporary storage medium.

The storage card I/F 7 is used as an interface of the storage card 8. The storage card I/F 7 is connected with the storage card 8 as a rewritable non-volatile storage, which can be detachably installed in a groove of the main body of the thermal imaging device 13 and can record the data such as the thermal imaging data according to the control of the control part 10.

The flash memory 9 stores control programs and different kinds of data used in different control.

The operation part 11 is used for a user to perform operation. The control part 10 executes the corresponding program according to an operation signal of the operation part 11. As shown in FIG. 2, the operation part 11 may include a record key 21, a switch key 22, an analysis key 23, a menu key 24, a mode key 25, a processing key 26, an enter key 27, a direction key 28, a position key 29, and a replay key. The record key 21 is used for record operation, the switch key 22 is used for switch operation, the analysis key 23 is used for analysis operation, the menu key 24 is used for entering into or exiting from a menu mode, the mode key 25 is used for entering into or exiting from an analysis reference mode, the processing key 26 is used for entering into or exiting from a processing mode, the enter key 27 is used for determining operation, the direction key 28 is used for selecting menu items, and the replay key is used for entering into or exiting from a replay mode. However, the invention is not limited thereto. A touch screen 30 or a phonic part (not shown) may be used for realizing related operation.

The storage medium, the reference image, the constituted data, morphological constituted data, auxiliary constituted data, an analysis area, an analysis mode, a computing object, a processing object, a main object, a specified position and dimension, a position parameter, position information, a self-adaptive area, and self-adaption are described hereinbelow.

The storage medium may be a storage medium in the thermal imaging device 13, such as a non-volatile storage medium i.e. the flash memory 9 or the storage card 8 and a volatile storage medium i.e. the temporary storage part 6, and may be other storage mediums connected with the thermal imaging device 13 wiredly or wirelessly, such as a storage medium in other devices connected with the communication I/F 5 wiredly or wirelessly, i.e. other storage devices, thermal imaging devices, or computers, or a storage medium in a network destination. Preferably, the data such as the constituted data is prestored in the thermal imaging device 13 or the connected non-volatile storage medium (such as the flash memory 9).

The reference image reflecting morphological characters of a photographed body may be the image of the reference image and the infrared thermal image displayed together in FIG. 5. A reference image TU1 (semitransparent) in 501 reflects the texture and contour of the photographed body, which is vivid for understanding. This reference image, such as a visible light image, an infrared thermal image of a photographed body, and an image with texture and contour characters in advance, is semitransparently displayed. A reference image T1 (an edge contour image which may be opaque or semitransparent) in 502 and a reference image W1 (a texture image which may be opaque or semitransparent) in 503 may be transparent to show the infrared thermal image at other pixels except the superimposed part. In addition, the morphological character may be the morphological character of the whole or local photographed body.

The constituted data is the constituted data related to the reference image and the analysis area, and may be vector image data, lattice data, or data including the vector image data and the lattice data. The lattice data may be lattice image data or the lattice data of the thermal imaging data. The constituted data may be divided into the morphological constituted data and the auxiliary constituted data. The constituted data for acquiring the reference image reflecting the morphological characters of the photographed body in FIG. 5 is called the morphological constituted data, and the reference image reflecting the morphological character may be acquired by one or more morphological constituted data or the morphological constituted data combined with the auxiliary constituted data. The constituted data for acquiring the reference image reflecting the morphological character may be one or more and at least include one morphological constituted data.

In the embodiment, the constituted data except the morphological constituted data is called auxiliary constituted data, which may be used for acquiring an analysis area. In FIG. 6, an analysis area F1 is an analysis area set in the prior art, with weak reference for photographing when used alone. Preferably, the reference image is acquired by the morphological constituted data and the auxiliary constituted data together. For example, a contour image T1, an analysis area F1, and an infrared thermal image in FIG. 7 are displayed together, thereby providing a prompt to improve the reference effect of T1 and to avoid the weak reference of F1.

In the embodiment, the storage medium at least stores one morphological constituted data. The constituted data may be stored in the storage medium in a way that one constituted data corresponds to one file such as an image file or a graph file, may be stored in the storage medium after processed in an external computer, or may be acquired according to the thermal imaging data photographed by the thermal imaging device 13 or the data after specified processing. The constituted data may be stored in a database, and the constituted data may be correspondingly stored to a specified field. Preferably, the auxiliary constituted data and the morphological constituted data is related and stored in the storage medium, and a specified position relation between the objects acquired by the auxiliary constituted data and the morphological constituted data is stored. The auxiliary constituted data may be as attribute data of the morphological constituted data.

The analysis area corresponds to the part in the infrared thermal image to be analyzed, such as area units i.e. points, lines, or planes, or a combination of the multiple area units. In the embodiment, the constituted data for acquiring the analysis area may be the morphological constituted data and/or the auxiliary constituted data.

One embodiment of the constituted data stored in the storage medium is described according to a table in FIG. 3 (called Table 3 hereinbelow). The multiple body information and the morphological constituted data (constituted data of T1 to constituted data of T4) to which each body information corresponds is related via Table 3. In addition, if the relevance is built via index information (such as a file name) of the morphological constituted data stored in Table 3, the storage medium further stores files of the morphological constituted data to which the index information (such as the file name) corresponds. The body information is the information related to a photographed body, such as the information representing a position, a type, a number, a name of the photographed body, or a combination thereof. In Table 3, some different body information (such as, a photographed body 3, a photographed body 4, and a photographed body 5 in Table 3) is related to the same morphological constituted data. In an occasion of infrared detection, there are a lot of different photographed bodies with the same shapes. As the morphological constituted data is stored with the body information in Table 3, a user can select the constituted data according to the body information recognized on the scene, thereby avoiding confusion caused by incorrect selection of the constituted data and reducing redundant data.

According to a table in FIG. 4 (called Table 4 hereinbelow), one preferred embodiment of the constituted data stored in the storage medium is described. That is, multiple body information and multiple constituted data related to the each body information may be stored. In Table 4, there is the multiple constituted data (the type of the morphological constituted data includes a benchmark 1, a benchmark 2, and a benchmark 3, the type of the auxiliary constituted data includes an auxiliary 1) related to the multiple body information, analysis mode information of “analysis mode 1” when the constituted data of the auxiliary 1 acquires the analysis area, and the universal analysis mode information of “analysis mode 2” when the constituted data of different types acquires the analysis area. The information (not shown) of a specified position relation between the objects acquired by the constituted data related to the same body information is stored. The specified position relation is a specified relative position relation. In detail, for example, in an original storing state (in a state without displacement, scaling, or rotation), it is the position information (information of coordinate positions, dimensions, or rotating angles) of the object acquired by the constituted data of the benchmark 2, the benchmark 3, and the auxiliary 1 related to the same body information, relative to the object acquired by the constituted data of the benchmark 1. In addition, the specified position relation may be the position information (the information of coordinate positions, dimensions, or rotating angles) of the stored objects in the same reference frame (such as in an infrared thermal image). In Table 4, the information of the specified position relation is as one attribute of the constituted data, or may be stored alone. In addition, if the relevance is built via the index information (such as a file name) of the constituted data stored in Table 4, the file of the constituted data to which the index information (such as the file name) corresponds may be further stored in the storage medium. In Table 4, the constituted data of different types is classified and stored according to a specified type, such as, according to display effects of the objects acquired by the constituted data. That is, the benchmark 1 corresponds to the contour, the benchmark 2 corresponds to the infrared thermal image (such as a local standard body thermal image) processed in advance, the benchmark 3 corresponds to the texture, and the auxiliary 1 corresponds to a focused attention area. In addition, classification may be performed according to a photographing use or a data type (the vector image data, lattice data). In addition, the classification is not limited to the single constituted data and may be performed for a combination of multiple constituted data. In addition, the invention is not limited to the embodiment in Table 4. For example, the storage medium may store the constituted data via graph files, image files (for example, the file name includes the corresponding body information), and the files may be classified via file folders.

Although the information of the specified position relation between the objects acquired by the constituted data related to the same body information is prestored in the storage medium in the embodiment of Table 4, it may not be stored. For example, users may give the specified position relation between the objects, or the specified position relation between the objects may be set according to a default position rule of the thermal imaging device 13. In addition, the specified position relation between a designated object and the constituted data acquired by computing and/or processing the designated object may be determined by a corresponding computing and/or processing rule. For example, the specified position relation between the contour and the analysis area acquired after scaling and deforming the contour may be determined according to a base point of scaling and deforming, a scaling ratio, and a deforming ratio. In the following text, the specified position relation between the objects acquired by the constituted data is sometimes also called the specified position relation between the constituted data.

The specified position relation of the objects (or the constituted data) is described as an example of two objects. As the specified position relation between the two objects is unchanged, according to a position parameter (a position, a dimension, or a rotating angle) of one object in an infrared thermal image, the position parameter (the position, the dimension, or the rotating angle) of the other object in the infrared thermal image may be set. When one of the objects performs a displacement, the other object also performs the same displacement, to remain the relative position therebetween. When one of the objects performs dimension scaling, the other object performs the same dimension scaling based on the same base point, to remain the same dimension scale. When one of the objects performs angle rotation, the other object rotates the same angle based on the same base point, to remain the same relative rotating angle. In a special condition, as one object is a feature point (a feature coordinate point) of the other object, when the other object performs a displacement, the feature point performs the same displacement; when the other object scales relative to a scaling base point, by using the scaling base point as a coordinate origin, the coordinate (X2, Y2) of the feature point relative to the scaling base point after scaling is equal to a product (X1*S, Y1*S) of the coordinate (X1, Y1) of the feature point relative to the scaling base point before scaling and a scaling ratio S; when the other object rotates an angle P (such as anticlockwise), the feature point rotates the same angle based on the same rotating base point, and the relation between the coordinate (X2, Y2) of the feature point relative to the rotating base point after rotation and the coordinate (X1, Y1) of the feature point relative to the rotating base point before rotation is (X2, Y2)=(X1 cos P−Y1 sin P, Y1 cos P+X1 sin P).

The analysis mode represents an analysis computing rule used by an analysis result acquired after specified analysis for the thermal imaging data determined on the analysis area, such as computing temperature values, i.e. computing the maximum temperature, the average temperature, the minimum temperature, or the percentage ratio, and may include a computing relation between different area units, such as the difference in temperature. However, it is not limited to the temperature value computing, and may also relate to analysis computing rules of different analysis related to the thermal imaging data or the infrared thermal image.

Preferably, the analysis mode information related to the analysis mode is related and stored with the corresponding constituted data in the storage medium, which may be used when the constituted data acquires the analysis area (the relevance method is that the analysis mode may be as the attribute information of the constituted data), thereby facilitating to prepare the complicated analysis area and analyze in the analysis mode with simple operation. With regard to different body information, the analysis mode information may be different in direct to the same or different constituted data. In FIG. 4, with regard to “analysis mode 1” related to the constituted data of “auxiliary 1”, the information (the analysis mode information of F1) of the analysis mode 1 of a photographed body 1 is to compute the maximum temperature of an area unit S01, the maximum temperature of an area unit S02, and the difference of the maximum temperature of the area units S01 and S02 (the analysis area F1 acquired by the constituted data of F1 includes area units S01, S02). The information (the analysis mode information of F2) of the analysis mode 1 of a photographed body 2 is to compute the average temperature, the maximum temperature in the area (the analysis area F2 acquired by the constituted data of F2), and the difference of the maximum temperature and the average temperature. With regard to different body information, the analysis mode information may be universal to the same or different constituted data. For example, the information of the analysis mode 2 is to compute the maximum temperature, the average temperature in the analysis area acquired by the determined constituted data, and the difference of the maximum temperature and the average temperature, which may be universal for all of the constituted data in Table 4 and may be the analysis mode information related to the constituted data of different types in Table 4.

The processing object can acquire the morphological constituted data via processing according to a specified processing rule. The processing object may be the morphological constituted data stored in the storage medium (such as the flash memory 9), such as the morphological constituted data of “benchmark 1”, “benchmark 2”, and “benchmark 3” in Table 4, may be the thermal imaging data or infrared thermal image acquired by the thermal image file in the storage card 8, or may be the thermal imaging data acquired by photographing in the temporary storage part 6. The processing object and the processing rule may be configured in advance. The processing may be specified image processing for the processing object, such as cutting, feature extracting (such as threshold range extracting, edge extracting), enhancing, filtering, pseudo-color, color adjustment, or a combination thereof. Preferably, the processing rule at least includes the image processing for the processing object, such as “cutting”, “threshold range extracting”, “edge extracting”, or a combination thereof.

The cutting is to extract data of the processing object located in a cutting area.

The threshold range extracting is to extract data of the processing object located in a threshold range. The threshold range may be an AD value range of the thermal imaging data, a color-code range of the infrared thermal image, a threshold range of the temperature, a gray-scale range, a luminance range, or a color range, and it may be prestored or may be set or adjusted by the users. The threshold range extracting may be to extract a temperature band or a color band in the infrared thermal image (the processing object) to acquire the morphological constituted data, to extract pixels of specified colors in a visible light image (the processing object) to acquire the morphological constituted data, or to extract pixels of specified AD values in the thermal imaging data (the processing object) to acquire the morphological constituted data.

The edge extracting is to extract data of the edge contour based on the processing object according to a specified algorithm. For example, binaryzation may be performed for the infrared thermal image (the processing object) according to a specified threshold range. The specified threshold range may be a prestored threshold range, or the binary threshold range may be set manually as a binary image is displayed. The threshold range may be a set AD value range of the thermal imaging data, a threshold range of the temperature, a gray-scale range, or a color-code range. Then, a connected region of the image after the binaryzation is processed. Then, an edge detecting processing is performed for the connected region, thus to acquire edge contour data. Further, vectorization is performed for the acquired edge contour data. Other detailed processing methods may adopt mature methods in the field, and they are not described in detail.

The computing object can acquire auxiliary constituted data via computing according to a specified computing rule. The computing object may be “benchmark 1”, “benchmark 2”, “benchmark 3”, “auxiliary 1”, or a combination thereof in Table 4. The computing rule at least includes scaling, deforming, dividing, halving, computing a bounding rectangle, computing an inscribed rectangle, computing a center line, computing a feature point, or a combination thereof for the computing object. In addition, the user can designate the computing object according to the selection of the reference image or a synthesis object displayed on the display part 4, or designate from the constituted data of points, lines, or planes having the specified position relation with the reference image.

The specified position and specified dimension are the position and dimension of the reference image located in the infrared thermal image or further include the rotating angle. They may be parameters of the specified position and the specified dimension in a coordinate system of the display part (a display screen) (still in a display window of the infrared thermal image), or may be parameters of the specified position and specified dimension in a coordinate system of the infrared thermal image in the display window of the infrared thermal image. Further, a position setting part (the control part 10) only sets the position of the reference image located in the infrared thermal image, and the display dimension is the default original dimension, which is also considered as setting of the specified position and specified dimension.

For the reference image reflecting the morphological characters, the position parameter is the specified position and specified dimension of the reference image located in the infrared thermal image. For the analysis area, the position parameter is the position (for example, the analysis area is a point), the dimension, or the rotating angle of the analysis area located in the infrared thermal image. In the embodiment, the position parameter may be the position parameter in the coordinate system of the display part (the display screen) (still in the display window of the infrared thermal image), or may be the position parameter in the coordinate system of the infrared thermal image in the display window of the infrared thermal image.

The position information may be the position information related to the constituted data, the information of the position parameter, or the information of the rule for acquiring the position parameter.

When there is multiple constituted data with the specified position relation, the main object is the object acquired by one or multiple constituted data designated therefrom. When the main object is designated, the position setting part is used for setting the position parameter of the main object in the infrared thermal image, and then for setting the position parameter of the other object in the infrared thermal image according to the position parameter of the main object in the infrared thermal image and the specified position relation between the other object and the main object.

The self-adaptive area is a specified area in the infrared thermal image. For example, in the embodiment, in the infrared thermal image, 90% of a centering window area Z1 of the infrared thermal image may be the self-adaptive area.

The self-adaption is the position setting embodiment that the non-overflow maximization scaling with a fixed aspect ratio in a self-adaptive area is performed for a self-adaptive object at a designated position (or including a specified rotating angle) in the self-adaptive area to acquire the dimension after self-adaption, thus to acquire the specified position and specified dimension of the self-adaptive object located in the infrared thermal image. The embodiment of the self-adaptive object centered and self-adapted in Z1 is taken for example. The ratio of the X axis and the ratio of the Y axis between the self-adaptive area Z1 (the dimension X1, Y1) and the self-adaptive object (the original dimension X2, Y2 of the self-adaptive object) are computed, and the smaller ratio between X1/X2 and Y1/Y2 is selected as a scaling ratio of the self-adaptive object during centering based on a center point of the self-adaptive object, thereby acquiring the position parameter of the self-adaptive object located in the infrared thermal image. The self-adaptive object may be the analysis area or the reference image. The position parameter is set via self-adaption, thereby facilitating to standardize and adjust the position parameter of the analysis area or the reference image located in the infrared thermal image. In the following embodiments, the mentioned self-adaption is with the example that the self-adaptive object is centered and self-adapted in Z1.

According to different embodiments of display control, the reference image displayed with the infrared thermal image may be one or include multiple synthesis objects synthesized with the infrared thermal image. The single synthesis object may be acquired by one or multiple constituted data. When the multiple constituted data is used to acquire one synthesis object, the position setting part may only set the specified position and specified dimension of the synthesis object located in the infrared thermal image and is not necessary to set the position parameter of the object located in the infrared thermal image acquired by each of the constituted data, respectively. When the reference image includes multiple synthesis objects, the position setting part may set the position parameter of each synthesis object located in the infrared thermal image, respectively.

The detailed operation and control flows of the first embodiment are described in detail hereinbelow. In the embodiment, supposing that the flash memory 9 stores the contents as shown in FIG. 4, the applied scene may be to photograph bodies in a substation. When the power is on, the interior circuits of the control part 10 are initialized, and then a standby photographing mode is entered, that is, the photographing part 1 acquires thermal imaging data, the image processing part 2 performs specified processing for the thermal imaging data acquired by the photographing part 1 to store in the temporary storage part 6, and the control part 10 controls the display controlling part 3 to allow the display part 4 to continuously display the infrared thermal image in a dynamic image mode. In the state, the control part 10 continuously monitors whether other modes are switched according to the predetermined operation or shutdown operation is performed. If yes, corresponding processing control is performed.

When the enter key is pressed at length as the algorithm is selected, a parameter bar is displayed for inputting the parameter (not shown). One or more computing rule may be selected for the selected computing object.

Referring to FIG. 12, the function and effect of the analysis area acquired by computing and/or processing are described.

Referring to FIG. 12 (101), the constituted data of the contour T1 as a computing object is scaled and deformed to acquire an analysis area F101 by using a center point of the contour T1 as a base point, which may be used for analyzing and computing temperature distribution of a specified area on the main part of the photographed body, thereby reducing influence of surrounding environment on assessment.

Referring to FIG. 12 (102), the constituted data of the contour T1 is as the computing object, and the algorithm parameter is eight-equal part, to acquire the eight-equal analysis area F102, which is used for analyzing temperature distribution of different sections of the main part of the photographed body.

Referring to FIG. 12 (103), the constituted data of the contour T1 is as the computing object, and the algorithm parameter is to compute a bounding rectangle, to acquire a bounding rectangle F103, which is used for analyzing and measuring the maximum temperature of the photographed body, thereby reducing influence of high-temperature bodies in the background.

Referring to FIG. 12 (104), the constituted data of TU1 (TU1 is a local infrared thermal image) is as the processing object, and the processing rule may be edge contour extracting, to acquire an analysis area F104 of the edge contour, which may be used for analyzing and measuring the maximum temperature of the photographed body, thereby reducing influence of high-temperature bodies in the background.

Obviously, the designated object may be processed and/or computed to acquire the constituted data. In addition, the configuration menus of “object processing CD1” and “object computing CD2” may be merged to one configuration menu. One or more processing rule and/or one or more computing rule may be selected for the designated object (the constituted data prestored in FIG. 4, the thermal image file in the storage card 8, the thermal imaging data acquired via photographing), and the processing and/or computing is collectively called processing for the designated object. In addition, the related processing rule or computing rule may be configured without directing to the specified constituted data, which may be as the default configuration suitable for the subsequent selected constituted data.

Referring to the configuration interface in FIG. 13, the configuration of “analysis configuration CD3” is described.

The “analysis configuration CD3” is used for setting a specified designated type, a position rule, a synthesis parameter, an analysis mode of the constituted data related to the reference image and the analysis area under a non-switch state in the analysis reference mode by users.

The constituted data CD31 displays the information of the constituted data to be selected, such as the type information “benchmark 1”, “benchmark 2”, “benchmark 3”, or “auxiliary 1” acquired from Table 4. In addition, other type information, such as the type information “benchmark 1 (processing)” which the processing object set in “object processing CD1” combined with the specified processing rule represents, or the type information “benchmark 1 (computing)” which the computing object set in “object computing CD2” combined with the specified computing rule represents, may also be displayed for selection.

The reference image CD32 is provided for users to select the constituted data for acquiring the reference image. One or more constituted data may be selected to acquire the reference image.

The position rule CD33 is used for configuring the position rule related with the position parameter of the reference image and the analysis area located in the infrared thermal image by users.

The main object is selected to acquire the constituted data of the main object. As shown in FIG. 13, the main object may be selected from the constituted data CD31, and may be the main object acquired by the reference image or the constituted data of other objects. The constituted data for acquiring the main object may be one or more constituted data with the specified position relation, such as the morphological constituted data and/or the constituted data related to the morphological constituted data. In addition, the computing object designated in the morphological constituted data or the related constituted data is combined with a specified computing rule to acquire the main object, or the processing object designated in the morphological constituted data is combined with a specified processing rule to acquire the main object. Usually, the set main object represents the focused observed area. By exchanging the main object, the exchange of the reference image and the analysis area in different display positions can be realized, thereby realizing different photographing aims. In addition, the user may select the reference image (one or more synthesis objects therein) displayed on the display part 4 as the main object.

When the main object is designated, according to the specified position relation between the other object and the main object and the position parameter of the main object located in the infrared thermal image, the position parameter of the other object located in the infrared thermal image may be set. When there is no designated main object, the position parameter of the object acquired by the constituted data selected in the “reference image CD32” and “analysis area CD35” is set according to the respective position rule.

The self-adaption is used for configuring a position setting mode of the self-adaption and designating a self-adaptive object. By selecting the self-adaption and pressing the enter key at length, the position, dimension, and rotating angle of the self-adaptive area located in the infrared thermal image may be set, and the position and rotating angle of the self-adaptive object located in the self-adaptive area may be set. In the embodiment, 90% of a centering window area of the infrared thermal image is as the self-adaptive area, which is called Z1 for short, and the self-adaptive object is centered and self-adapted in Z1. The self-adaptive object may be selected from the constituted data CD31.

The designated position is used for configuring the position parameter of the object acquired by the selected constituted data located in the infrared thermal image by users. When the user selects the “designated position bar”, an input bar (not shown) is displayed, and the user can input the position, dimension, and rotating angle of the object acquired by the selected constituted data located in the infrared thermal image. When the above is not input, the position origin may be defaulted as a top-left corner of the infrared thermal image, the dimension is an original dimension, and the rotating angle is zero.

When the relevance is selected, the position parameter of the object acquired by the constituted data located in the infrared thermal image is acquired, according to the position information related to the selected constituted data in advance.

The synthesis parameter CD34 is used for configuring the synthesis parameter of the reference image acquired by the selected constituted data and the infrared thermal image. The synthesis parameter may be a transparency ratio, a color, a line-type (not shown), a synthesized sequence when the reference image includes a plurality of synthesis objects, or the synthesis parameter related to the constituted data.

The analysis area CD35 is provided for users to configure the type of the analysis area. The user can select the constituted data for acquiring the analysis area from the constituted data CD31. In addition, when the “analysis area CD35” is selected and the enter key is pressed at length, the configuration interface of the analysis area and the analysis mode as shown in FIG. 15 is displayed, which is provided for the users to set the analysis area of “point”, “line”, “plane” in the reference image or the infrared thermal image. In addition, the range of the analysis area may be set. Taking an example of T1 in FIG. 15, the analysis area may be located in the area of T1, out of the area of T1, or on the edge contour of T1.

The constituted data of the analysis area may be acquired according to the morphological constituted data stored in the storage medium or the constituted data related to the morphological constituted data, or may be acquired by corresponding processing for the designated object in the morphological constituted data stored in the storage medium or the related constituted data according to the specified computing rule and/or processing rule. One or more constituted data is selected to acquire the analysis area. In addition, the analysis area of “point, line, plane” may be manually operated, which may be set according to the reference image, thereby the set analysis area facilitating subsequent use. The user may select the setting mode of the analysis area according to aims of infrared detection. When the analysis area is configured, the area units in the analysis area may be numbered manually or automatically (F1 in FIG. 15 includes frame area units S01, S02), or the prestored constituted data has the respective number, using as the number of the analysis area.

The analysis mode CD36 is provided for users to configure the analysis mode to which the analysis area corresponds. The information to be selected may be the analysis mode information acquired from Table 4 (the analysis mode 1, the analysis mode 2) or stored in advance. In addition, when the “analysis mode CD36” is selected and the enter key is pressed at length, the configuration interface of the analysis area and the analysis mode as shown in FIG. 15 is displayed, and the newly set analysis mode may also be displayed for selection.

Referring to FIG. 15, the configuration interface of the analysis area and the analysis mode, including an adjusting bar SZ0 of the analysis area, an analysis area setting bar SZ1, and an analysis mode setting bar SZ2, is described. A photographed body 1 is taken for example.

In the adjusting bar SZ0, for adjusting the specified position relation between the analysis area and the reference image, the reference image and the analysis area are displayed for adjustment, such as, the reference image T1 (benchmark 1) selected in “reference image CD32” and the analysis area F1 (auxiliary 1) selected in “analysis area CD35” in the embodiment. In the adjusting bar SZ0, the users can perform operation, such as decreasing, changing positions, adjusting, changing types (point, line, plane), or setting new area units for the area units S01, S02 in the analysis area F1.

The analysis area setting bar SZ1 is used for setting the analysis area to which the reference image T1 corresponds, such as points, lines, planes, or the similar computing rule in “object computing CD1”. At that moment, the computing object is usually defaulted as the reference image T1.

The analysis mode setting bar SZ2 is used for setting the analysis mode. The “area” is used for selecting a number of the area unit displayed in SZ0, such as S01, S02, the “mode” may be maximum, minimum, or average temperature, the “calculation” may be addition, subtraction, multiplication, or division, and the “relation” may be logic relation of AND, OR, NOT.

After the setting is finished and determined, the constituted data of the reference image and the configured analysis area, the specified position relation (such as the position parameter of the analysis area F1 located in the reference image T1) of the analysis area relative to the reference image, the analysis mode to which the analysis area corresponds are related and stored to a record medium, such as recording to Table 4 in the flash memory 9.

The switch CD4 is used for setting the configuration information related to a switch object when the switch key is pressed once in the state of displaying the reference image configured in “analysis configuration CD3” and the infrared thermal image together in the analysis reference mode. Referring to the configuration interface as shown in FIG. 14, the configuration of “switch CD4” is described. The switched configuration information may be the type of the switched constituted data of the reference image, the position rule of the object acquired by the constituted data after switch, the synthesis parameter (such as a superimposed sequence, a transparency ratio, or a color), the constituted data of the analysis area, the analysis mode, or a combination thereof. As the detailed configuring items are similar to that of “analysis configuration CD3”, the description is omitted. The infrared thermal image may be as the switch object. An arrow in the switch CD4 is used for setting (increasing, amending, deleting) a switch rule. For example, the next switch interface may be entered via the arrow, thereby configuring the configuration information of more switch objects.

The “record configuration CD5” is provided for users to record the specified record information related and stored with the infrared data. The specified record information is the record information that is specified. The specified record information may be the body information, the constituted data, identity information (such as a file name or a number of the constituted data) of the constituted data, the analysis mode, the analysis result, the position information (in response to the record instruction), or a combination thereof.

In the first embodiment, the photographing aim of the user is to detect the global distribution of the thermal field of the photographed body and the focused analysis part (the area represented by the auxiliary 1). To realize the photographing aim conveniently, the configuration is set in “analysis configuration CD3” as shown in FIG. 13. The reference image is “benchmark 1” and “auxiliary 1”, the position rule is the benchmark 1 (the main object), the self-adaptive area Z1, and self-adaptive centering, the synthesis parameter is that the transparency ratio is one, the synthesis sequence of the benchmark 1 is one, the synthesis sequence of the auxiliary 1 is two, and the color is defaulted, the analysis area is the auxiliary 1, and the analysis mode is the analysis mode 1.

If there is uncertainty, the user may walk closer to photograph the focused analysis part (the area represented by the auxiliary 1) of the photographed body. The configuration set in “switch CD4” is as shown in FIG. 14. The reference image is “benchmark 1” and “auxiliary 1”, the position rule is the auxiliary 1 (the main object), the self-adaption, the self-adaptive area Z1, and centering, the synthesis parameter is that the transparency ratio is one, the synthesis sequence of the benchmark 1 is one, and the synthesis sequence of the auxiliary 1 is two, the analysis area is the auxiliary 1, and the analysis mode is the analysis mode 1.

When the switch key is pressed once, the displaying of “benchmark 1 (main object), auxiliary 1” and the infrared thermal image together is switched to the displaying of “benchmark 1, auxiliary 1 (main object)” and the infrared thermal image together. When the switch key is pressed again, the display state returns to the displaying of “benchmark 1 (main object), auxiliary 1” and the infrared thermal image together. As the different main objects are used, different control modes of the attention focus are entered.

In the first embodiment, the configuration as shown in FIG. 13 and FIG. 14 is performed, and part of the constituted data in Table 4 may be used for configuring the reference image and the analysis area. However, according to the description of the menus in FIG. 9 to FIG. 14, the user may configure the reference image with different effects and the analysis area with the analysis function according to the constituted data in Table 4, including combination of the designated object and the computing rule and/or the processing rule. When at least one of the constituted data of the reference image, the position rule, the synthesis parameter, the constituted data of the analysis area, and the analysis mode is different, the analysis configuration with different uses may be acquired. The analysis configuration with different uses and effects may be acquired via the switch configuration.

In addition, when the constituted data is shown as FIG. 3, the user may configure the related constituted data, the position rule, the synthesis parameter, the reference image, the analysis area, and the analysis mode via “analysis configuration CD3” or “switch CD4”, thereby acquiring the analysis configuration with different uses.

When the setting operation is finished and the enter key is pressed, the control part 10 (the configuration part) allows the each set configuration to be related and stored in the flash memory 9 (such as, as a configuration file), which is used as the default configuration of the thermal imaging device 13, without setting during each time of use, and then returns to the standby photographing state. Although the embodiment of performing the configuration by the users is described, the invention is not limited thereto. When the thermal imaging device 13 leaves the factory, the configuration related to the respective processing may be set, without manual setting, or the configuration file may be loaded to the thermal imaging device 13 before photographing after the configuration is performed in an external computer. Otherwise, the user may perform the configuration of part contents mentioned above.

The overall function of the thermal imaging device 13 is described hereinbelow.

An acquiring part, such as the photographing part 1, is used for acquiring the thermal imaging data.

A reference image designating part (the control part 10) is used for designating the constituted data for acquiring the reference image reflecting the morphological characters of a photographed body. According to the constituted data stored in the storage medium, the constituted data of the reference image can be designated. For example, the reference image reflecting the morphological characters may be acquired by designating one morphological constituted data related to the reference image or multiple constituted data at least including one morphological constituted data from the “benchmark 1”, “benchmark 2”, “benchmark 3”, and “auxiliary 1” stored in FIG. 4, by designating the morphological constituted data “benchmark 1 (processing)” represented by the processing object (the morphological constituted data, or the morphological constituted data and the auxiliary constituted data) combined with the specified processing rule, or by designating the auxiliary constituted data “benchmark 1 (computing)” represented by the computing object combined with the specified computing rule and one morphological constituted data. In addition, according to the thermal imaging data acquired via photographing, the constituted data of the reference image may be designated.

The reference image designating part is used for designating the constituted data for acquiring the reference image according to the constituted data stored in the storage medium. For example, the constituted data for acquiring the reference image may be selected from the constituted data stored in the storage medium. The morphological constituted data may be acquired according to the processing object and the processing rule designated from the constituted data stored in the storage medium. The reference image reflecting the morphological character of the photographed body may be acquired according to the auxiliary constituted data acquired according to the computing object and computing rule designated from the constituted data stored in the storage medium and the morphological constituted data. Besides the prestored constituted data, the suitable constituted data or the suitable reference image acquired thereby may be acquired via processing or computing.

A reference image position setting part (the control part 10) is used for setting the position parameter (the specified position and specified dimension) of the reference image reflecting the morphological characters acquired by the designated constituted data in an infrared thermal image. In the detailed position setting embodiment, the position parameter of the reference image may be (automatically) set according to a specified position rule. For example, according to the constituted data stored in the storage medium and the related position information, the position parameter of the reference image acquired by the constituted data represented by the position information in the infrared thermal image may set as the position parameter of the reference image acquired by the constituted data located in the infrared thermal image. Further, according to a specified self-adaptive area, the position parameter of the reference image located in the infrared thermal image may be automatically set. Further, a main object having the specified position relation with the reference image may be determined first and the position parameter of the main object located in the infrared thermal image may be set, and then according to the position parameter of the main object in the infrared thermal image and the specified position relation between the reference image and the main object, the position parameter of the reference image in the infrared thermal image may be set. According to the designated position default by the thermal imaging device 13, the position parameter of the reference image may be set.

In addition, according to operation (such as inputting the position parameter) of the users, the position parameter of the reference image may be set.

A display controlling part (the control part 10) is used for controlling the reference image with the specified dimension acquired by the designated constituted data to be displayed with the infrared thermal image generated by the thermal imaging data acquired by the photographing part together according to the specified position. There are multiple embodiments of displaying with the infrared thermal image.

When the reference image is one synthesis object, according to the specified position, it is continuously synthesized with the infrared thermal image generated by the thermal imaging data acquired by the photographing part, and then the synthesis image of the reference image and the infrared thermal image is displayed, thereby realizing the simultaneous display. In the embodiment, the synthesis may be performed according to a specified transparency ratio. The specified transparency ratio may be a fixed value, such as a default value stored in the thermal imaging device 13, a setting value set via the operation part 11 by the users, or the information related to the transparency ratio in the attribute of the constituted data of the acquired synthesis object. The transparency ratio of the synthesis object represents a ratio of the synthesis object and the synthesis pixels acquired by the synthesis object and the background (such as the infrared thermal image) during synthesis. For example, when one synthesis object is synthesized with the background, according to “image data of synthesis object×transparency ratio of synthesis object+image data of background×(1−transparency ratio of synthesis object)”, the image data of the synthesized pixels is acquired. In addition, when the parameter of the transparency ratio is not set, the default transparency ratio is one.

In one embodiment, when there are several synthesis objects to be synthesized with the background (such as the infrared thermal image), according to the synthesis sequence and transparency ratio of each synthesis object, the synthesis objects are successively synthesized to acquire the final synthesis image. For example, when there are a synthesis object 1 (the synthesis sequence is one) and a synthesis object 2 (the synthesis sequence is two), the synthesis object 1 is first synthesized with the background according to the transparency ratio thereof to acquire medium data “image data of the synthesis object 1×the transparency ratio of the synthesis object 1+image data of the background×(1−the transparency ratio of the synthesis object 1)”, and then the synthesis object 2 is synthesized with the medium data according to the transparency ratio thereof, that is, the acquired synthesis pixel is acquired according to the following formula: the synthesis object 2*the transparency ratio of the synthesis object 2+the medium data*(1−the transparency ratio of the synthesis object 2).

In one embodiment, according to the pixel position of the reference image in the infrared thermal image, the selective pseudo-color processing is performed for the thermal imaging data acquired by photographing to acquire the displayed image. In detail, the image data of the reference image at the superimposed pixel position may be as the image data of the superimposed image at the pixel position, the pseudo-color conversion is not performed for the thermal imaging data at the superimposed pixel position and is only performed for the thermal imaging data except the superimposed pixel position to acquire the image data of the infrared thermal image, thereby generating the displayed image, which may accelerate the processing speed in certain application. For the reference image of an edge contour, if this mode is used to process the reference image or the auxiliary object, corresponding identifying information may be first attached to the attribute of the constituted data. The pseudo-color processing performed for the thermal imaging data at the pixel position in the thermal imaging data to which the reference image corresponds is different from that for the thermal imaging data at other pixel positions, such as the pseudo-color processing of different pseudo-color plates or the pseudo-color processing after subtracting a specified value from the thermal imaging data at the pixel position in the thermal imaging data to which the reference image corresponds, to generate the synthesis image.

In one embodiment, for example, according to a threshold range (such as an AD value range) of the thermal imaging data acquired via photographing, the transparency ratio of the reference image synthesized with the thermal imaging data may be determined. In detail, the transparency ratio of the reference image synthesized with the infrared thermal image in the threshold range may be zero, and that outside of the threshold range may be one, thereby avoiding shading important parts (in the threshold range) of the infrared thermal image. In the embodiment, the specified transparency ratio may also be changeable values.

The display controlling part controls the display part 4 to display the reference image and the infrared thermal image, and controls to display image data of other specified information when the display interface is configured to further display other specified information. For example, in FIG. 8, the display image may include an image 802 of the reference image and the infrared thermal image and an image 801 of other specified information. Further, the analysis area may also be displayed, and preferably the analysis area may be displayed with the image of the morphological character as the reference in at least one of a color, a transparency ratio, or a line-type.

In addition, the display controlling part (the control part 10) may project the reference image on the infrared thermal image, based on a specified display device, thus to realize the simultaneous display. At that moment, the function of the synthesis processing of the image processing part 2 may be deleted.

An analysis area determining part is used for determining the constituted data of the analysis area. Preferably, the analysis area determining part may determine the constituted data of the analysis area from the constituted data having the specified position relation with the constituted data of the reference image. For example, in FIG. 13, the analysis area may be acquired by designating one or more constituted data from the related “benchmark 1”, “benchmark 2”, “benchmark 3”, and “auxiliary 1” with the specified position relation stored in the flash memory 9. The designated object is combined with the specified computing rule and/or processing rule, to acquire the constituted data of the analysis area. Preferably, the designated object may be the constituted data of the reference image or the constituted data of the object having the specified position relation with the reference image. The specified position relation between the reference image and the analysis area may be acquired according to the information of the specified position relation stored in the storage medium in advance, may be set by users, or may be determined according to the default position rule of the thermal imaging device 13. In addition, the specified position relation between the constituted data acquired by computing and/or processing the designated object and the designated object or other object having the specified position relation with the designated object may be determined by a corresponding computing rule or processing rule.

In addition, the constituted data of the analysis area may also be determined from the constituted data without the specified position relation. For example, the constituted data of the analysis area may be determined from the constituted data related to the constituted data of the reference image (there is no prestored specified position relation therebetween), and the position parameter therebetween may be set by users. In addition, the constituted data of the analysis area may also be determined according to the constituted data (such as points, lines, or planes) of the analysis area set by users. Due to the reference of the reference image, it is more convenient than the prior art.

An analysis area position setting part is used for setting the position parameter of the analysis area located in the infrared thermal image.

In one detailed position setting embodiment, the position parameter of the analysis area may be (automatically) set according to a specified position rule. For example, based on the constituted data and the related position information stored in the storage medium, the position parameter of the analysis area acquired by the constituted data represented by the position information in the infrared thermal image is set as the position parameter of the analysis area acquired by the constituted data in the infrared thermal image. Otherwise, according to a specified self-adaptive area, the position parameter of the analysis area located in the infrared thermal image may be automatically set. Otherwise, a main object having the specified position relation with the analysis area may be determined first and the position parameter of the main object in the infrared thermal image may be set, and then based on the specified position relation between the analysis area and the main object and the position parameter of the main object located in the infrared thermal image, the position parameter of the analysis area located in the infrared thermal image may be set. Otherwise, according to the designated position defaulted by the thermal imaging device 13, such as the default position parameter (at least including the position, the dimension, or the rotating angle), the position parameter of the analysis area may be set.

In addition, according the operation (such as inputting the position parameter) of the users, the position parameter of the analysis area may be set.

According to different application, the setting (the determination of the constituted data, the setting of the position parameter) of the analysis area and the reference image may have different sequences. For example, the analysis area position setting part may be used for setting the position parameter of the analysis area in the infrared thermal image, according to the position parameter of the reference image in the infrared thermal image set by the reference image position setting part and the specified position relation between the reference image and the analysis area. The reference image position setting part may be used for setting the specified position and specified dimension of the reference image in the infrared thermal image, according to the position parameter of the analysis area in the infrared thermal image set by the analysis area position setting part and the specified position relation between the reference image and the analysis area. Otherwise, the main object having the specified position relation with the analysis area and the reference image may be first determined and the position parameter of the main object located in the infrared thermal image may be set, and then based on the specified position relation between the above both and the main object and the position parameter of the main object in the infrared thermal image, the position parameters of the analysis area and the reference image in the infrared thermal image may be set.

A thermal image analyzing part is used for analyzing the thermal imaging data (including the data acquired after specified processing for the thermal imaging data) acquired by the acquiring part (the photographing part 1) according to a specified analysis mode, based on the analysis area with the position parameter, to acquire an analysis result. Preferably, the specified analysis mode at least includes one or a combination of the followings:

1) the analysis mode that is set according to the analysis mode information related and prestored with the constituted data of the determined analysis area, such as the analysis mode acquired according to the analysis mode information related and stored with the constituted data of the analysis area in Table 4;

2) the analysis mode that is set according to the analysis mode information related to the position rule or position information of the position parameter of the acquired analysis area, thereby achieving the flexible analysis and facilitating the use when the analysis area is changed with different position parameters;

3) the analysis mode acquired according to the analysis mode information related to a corresponding computing and/or processing rule and/or the analysis mode information related to a designated object, when the constituted data of the analysis area is acquired by computing and/or processing the designated object. In certain conditions, the analysis area acquired after deformation of a contour may adopt the same analysis mode of the contour, such as computing the maximum temperature, thereby simplifying the operation.

In addition, the analysis mode may be a default mode of the thermal imaging device 13 or set by users. Obviously, there may be multiple analysis modes in the above.

In one embodiment, the temperature analysis is taken for example. Based on the control of the control part 10, the image processing part 2 performs specified processing, such as modification or interpolation, for the thermal imaging data acquired by the photographing part 1, and based on the position parameter of the analysis area in the infrared thermal image, extracts the thermal imaging data determined by the set analysis area, performs temperature conversion to acquire the temperature values to which the thermal imaging data corresponds, and then analyzes the acquired temperature values according to the analysis mode. For example, when the analysis mode is to compute the maximum, the maximum temperature value may be extracted as the analysis result. When the analysis area includes a plurality of area units, such as the area units S01, S02 of the analysis area F1 in FIG. 6, the temperature conversion and analysis is performed for the thermal imaging data in each area unit one by one, to acquire the analysis result of each area unit, the computed analysis result is stored with the number of the area unit in a specified area of the temporary storage part 6, and then the interrelated analysis result is computed and acquired according to the relation of the units in the analysis mode and the analysis result of each area unit.

In addition, the temperature conversion of the thermal imaging data in the analysis area may be to convert all thermal imaging data in the analysis area to temperature values, to convert specified part thermal imaging data to the temperature values, or to decide the conversion of all thermal imaging data or the part thermal imaging data in the analysis area according to different analysis modes such as computing the maximum temperature, the minimum temperature, or the average temperature. For example, when the analysis mode is to compute the maximum temperature in the analysis area, with regard to the thermal imaging data in the analysis area, the AD values of the thermal imaging data are compared, the maximum AD value is converted to the temperature value, without converting all thermal imaging data in the analysis area to the temperature values. In addition, there are conditions including different algorithms. For example, when the maximum temperature is computed, according to the average value of AD values of a specified number of adjacent pixels instead of the single pixel, the AD value of the adjacent pixel with the maximum average is converted to the temperature value, and the average of the temperature values of the thermal imaging data of the adjacent pixel is as the maximum temperature value. The thermal imaging data is converted the temperature value after specified processing. In one embodiment, according to the radiation coefficient, environment temperature, humidity of the set photographed body, the distance between the photographed body and the thermal imaging device 13, and conversion coefficient between the AD values of the thermal imaging data and the temperature, the temperature values are acquired via the specified conversion formula. In addition, the thermal imaging data determined by the analysis area, as shown in FIG. 6, may be the thermal imaging data in the analysis units S01, S02, the thermal imaging data outside of the analysis units S01, S02, or the thermal imaging data of the pixels where the lines of the analysis units S01, S02 are. The attribute of the constituted data of the analysis area may be determined in advance.

In addition, the thermal image analysis is not limited to convert the thermal imaging data to temperature values, and the analysis may be to convert the thermal imaging data to radiation energy values, gray-scale values, or radiation ratio values. Obviously, the analysis for the acquired thermal imaging data is not limited to the single-frame thermal imaging data, and the analysis may also be used for the multi-frame thermal imaging data stored in the temporary storage part 6 or one-frame thermal imaging data acquired after integral calculation for the multi-frame thermal imaging data.

Referring to the flow chart in FIG. 16, the control steps of the analysis reference mode in the first embodiment are described. FIG. 17 is a schematic diagram showing display interfaces during a photographing and analyzing process for a photographed body 1 via the reference image. In the embodiment, the user may examine the analysis result via pressing the analysis key.

In step A01, the control part 10 continuously monitors if a user selects an analysis reference mode. In a standby photographing state, the display part 4 displays the dynamic infrared thermal image. According to the photographing angle and distance at that moment, the infrared thermal image in 1701 in FIG. 17 is acquired. As for a thermal image IR1 of the photographed body 1, in the prior art, the user may be confused by the photographing distance and parts of the photographed body 1, and may set the analysis area manually. To ensure the photographing correction of the photographed body 1, the setting convenience of the analysis area, and the analysis correction via the reference of the reference image, the user selects the analysis reference mode via the operation part 11 and performs step A02.

In step A02, the control part 10 performs designation of the constituted data of the reference image, as shown in steps S101-S107 in FIG. 18.

In step A03, the control part 10 performs setting processing of the position parameter of the reference image in the infrared thermal image, as shown in steps S201-S203 in FIG. 19.

In step A04, the control part 10 performs determination of the constituted data of the analysis area, as shown in steps S301-S303 in FIG. 20.

In step A05, the control part 10 performs determination processing of the analysis mode to which the analysis area corresponds, as shown in steps S401-S403 in FIG. 21.

In step A06, the control part 10 performs setting processing of the position parameter of the analysis area in the infrared thermal image, as shown in steps S501-S503 in FIG. 22.

In step A07, the thermal imaging data acquired via photographing is transferred to the temporary storage part 6.

In step A08, the analysis is performed. Based on the set analysis area F1, according to the specified analysis mode, the thermal imaging data acquired by the photographing part 1 is analyzed, to acquire an analysis result. For example, the image processing part 2 may convert the thermal imaging data (the thermal imaging data in S01, S02) determined by the analysis area F1 (S01, S02) to temperature values, and may compute according to the analysis mode acquired by the analysis mode information of F1 related to the analysis area F1. The computed analysis result data, such as the maximum temperature of the area units S01, S02 and the temperature difference between S01 and S02, is stored to a specified area of the temporary storage part 6.

In step A09, the reference image acquired by the determined constituted data based on the specified dimension set by the position setting part is displayed with the infrared thermal image according to a specified position. In detail, in the embodiment, the constituted data is the constituted data of T1 and the constituted data of F1. The reference image (T1 and F1) acquired after specified processing (such as scaling) is synthesized with the infrared thermal image according to the specified position, and the synthesized image data is stored in the temporary storage part 6. Then, the control part 10 controls the reference image and the infrared thermal image to be displayed on the display part 4. As shown in a display interface 1703, there is the greater difference between the thermal image IR1 of the photographed body and the contour image T1. If there is no reference image reflecting the morphological characters of the photographed body, the user fails to hold the shape of the thermal image IR1 of the photographed body, the imaging position, dimension, and angle in the infrared thermal image, thereby omitting focused measuring parts and causing complicated setting operation of the analysis area, which is not beneficial to subsequent use. Further, if there is no shape reference of T1, the reference effect of F1 is weak.

In step A10, the control part 10 detects if an analysis informing instruction is received. If no, enter into step A14 and determine if the analysis reference mode is exited. If no, return to step A07, and in the step A08, the newly acquired thermal imaging data is analyzed, and the analysis result replaces the analysis result stored before and is stored in the specified area of the temporary storage part 6. Then, in the step A09, the reference image is displayed with the infrared thermal image acquired by the photographed thermal imaging data, reflecting a continuous display state of the dynamic infrared thermal image continuously acquired and the reference image.

According to the visual reference of the contour image T1, the user can understand the shape requirement of the thermal image IR1 of the photographed body to be photographed, the imaging position, dimension, and angle in the infrared thermal image, and then adjust the photographing distance, angle, and imaging position between the optical part of the thermal imaging device 13 and the photographed body 1, to achieve a superimposed state of the thermal image IR1 of the photographed body and the contour image T1 visually in FIG. 17 (a display interface 1704). At this moment, the user presses the analysis key to enter step A11.

In the step A11, the analysis result is displayed. As shown in a display interface 1705 in FIG. 17, the analysis result stored in the specified area of the temporary storage part is displayed on the display part 4, and the user can make judgment according to the displayed analysis result J17. In addition, the analysis result may not be displayed. For example, the analysis result data for controlling other devices may be output from the communication interface I/F 5. In the display interface 1702 and 1703 in FIG. 17, the analysis area F1 is configured to be displayed, which facilities the users to observe the analysis parts, and it may be configured to be not displayed. The attention area (the analysis area F1) instructed by the reference image is not necessary to match the analysis area related to analysis.

In step A12, if the switch key is pressed is determined.

If pressed, perform the corresponding switch, and return to the step A02. According to the switch configuration, the constituted data is determined to acquire the reference image (including T1 and F1), the analysis area F1 is as a main object, the position parameter of the analysis area F1 in the infrared thermal image is first set, and then according to the position of the analysis area F1, the specified position and specified dimension of the reference image (including T1 and F1) in the infrared thermal image are set. The thermal image of the photographed body that is photographed according to the reference image is shown in a display interface 1706 in FIG. 17, and due to the difference of the photographing distances, the analysis result shown in the display interface 1706 is different from that in 1705, and the temperature different increases to 4.5. Thereby, the user can make overall judgment according to the analysis result.

The display effect of the analysis area F1 as the main object represents that the analysis part represented by the analysis area F1 is displayed in a self-adaptive area Z1 at the maximum. The part of the contour T1 is overflowed, which meets the applied demand and is acceptable. According to the different measuring aims, different main objects may be set to represent the focused area to be observed. The position parameter of the main object in the infrared thermal image may be used for configuring the position parameter of the reference image or the analysis area in the infrared thermal image, which is convenient and flexible.

In addition, the switch is not limited to the change of the position rule. The switch may be performed for the constituted data of the reference image, the constituted data of the analysis area, the position rule, the synthesis parameter, the analysis mode, or a combination thereof, thereby achieving different measuring or observing effects. Obviously, the multiple analysis areas and the corresponding analysis modes may be set for switch. The switch is one preferred embodiment, and the switch step Al2 may not be performed.

In step A13, if the analysis reference mode is exited is determined. If no, return to the step A07. If a user does not release the analysis key, in the step A12, the analysis result in real time acquired by analysis processing for the thermal imaging data acquired in the step A07 is displayed, and if the user releases the analysis key, the dynamic infrared thermal image and the reference image are displayed.

Referring to FIG. 18, the designation of the constituted data of the reference image is described.

In step S101, if there is default constituted data is determined. If yes, jump to step S107. The control part 10 selects the default constituted data. If no, perform step S102.

In step S102, based on Table 4 stored in the flash memory 9, the control part 10 (a body information selecting part) allows the display part 4 to display a specified number of the body selecting information at the specified position, such as a body selecting information list LB as shown in the display interface 1702 in FIG. 17.

In step S103, then according to the cognition of the photographed body 1 at the photographing scene, such as the equipment indicator at the scene, the “photographed body 1” displayed on the display part 4 is selected via the operation part 11. The control part 10 is used for selecting the body information according to the selection of the body selecting information.

In addition, when the body information in Table 4 is composed of attribute information of multiple attributes, the body information is finally selected via display and the multiple selections for the attribute information (the body selecting information) of multiple attributes of the body information. For example, supposing that “photographed body 1” is composed of the attribute information “substation 1”, “equipment area 1”, and “equipment 1” corresponding to the substation attribute, the equipment area attribute, and the equipment type attribute, the selection operation is to select “substation 1” from a specified number of the body selecting information (the attribute information) corresponding to the displayed substation attribute, to select “equipment area 1” from a specified number of the body selecting information (the attribute information) corresponding to the equipment area attribute, and then to select “equipment 1” from a specified number of the body selecting information (the attribute information) corresponding to the equipment type attribute, thus to finally select “photographed body 1”. The selection operation may be divided into the multiple selection of the attribute information to finally select the body information.

In step S104, the control part 10 determines if there is the constituted data (such as, only one constituted data is related) of a specified designated type in the constituted data related to the body information corresponding to the selected body selecting information.

If only one constituted data is related, the control part 10 may select the constituted data according to the body information to which the body selecting information selected by the users corresponds. For example, when the flash memory 9 stores the body information and the related constituted data as shown in FIG. 3, in step S107, the control part 10 determines the constituted data of T1 as the constituted data of the reference image.

When the flash memory 9 stores the body information and the related multiple types of the constituted data as shown in FIG. 4, in the embodiment, since the specified designated type of the constituted data is set in advance, the step S107 is performed, the control part 10 designates “constituted data of T1” and “constituted data of F1” as the constituted data according to “photographed body 1” and the specified designated type “benchmark 1” and “auxiliary 1”. If no, that is the selected body information in the step S103 is related to the constituted data of multiple types and the specified designated type is not set in advance, step S105 is performed.

In step S105, the control part 10 allows the display part 4 to display identity information of the respective constituted data for users to select. The identity information may be a file name, a number, or a thumbnail representing the identity indicator of the corresponding constituted data. For example, the thumbnail corresponding to the constituted data may be displayed for the users to select, and one or more therein may be selected.

In step S106, when the users perform selection, the step S107 is performed.

In step S107, the reference image designating part is used for designating the constituted data for acquiring the reference image. Then, the constituted data of T1, F1 read from the flash memory 9 and the specified position relation therebetween is transferred to the temporary storage part 6.

In the above embodiment, the constituted data designated by the reference image designating part may be the default constituted data, may be designated according to the constituted data related to the selected body information, or may be the constituted data satisfying the specified designated type automatically determined according to the specified designated type based on the constituted data stored in the storage medium. The way of designating the constituted data of the reference image according to the constituted data related to the body information may be to select the constituted data for acquiring the reference image from the constituted data related to the body information, or to designate the processed constituted data as the constituted data for acquiring the reference image after designating a processing object from the constituted data related to the body information. Otherwise, the constituted data may be designated, as the user selects the identity information of the constituted data. In addition, when the constituted data in the storage medium is not related to the body information, the steps S102, S103 are omitted, and the constituted data is selected according to the identity information of the constituted data. Further, the body information selecting step of the steps S102, S103 may be as one step before the determining step of the constituted data of the reference image, and is not limited to the determining step of the constituted data of the reference image. In addition, according to the operation of a specified key, the constituted data corresponding to the key is selected, and the constituted data corresponding to the triggering condition is determined based on the specified triggering condition.

Referring to FIG. 19, the setting processing of the position parameter of the reference image in the infrared thermal image is described.

In step S201, the control part 10 determines if there is a specified position rule. If yes, jump to step S203. If no, perform step S202.

In step S202, as the setting menu as shown in FIG. 9 and the corresponding prompt are displayed, the user is required to set the position rule. When finished, the position rule is record to the flash memory 9 as the subsequent default configuration.

In step S203, the position parameter of the reference image in the infrared thermal image is set.

In the embodiment, according to the preset position rule, that is, the type of the main object is “benchmark 1”, the self-adaption is performed for computing the position parameter of the contour T1 in the infrared thermal image according to a centered position of the self-adaptive area Z1, and then the position parameter of F1 in the infrared thermal image is determined according to the specified position relation between F1 of the reference image (including the contour T2 and F1) and the contour T1. According to the specified position relation therebetween and the position parameter of the contour T1 in the infrared thermal image, the scaling base point (such as a center point) of the contour T1 is used as the scaling base point of F1, F1 is scaled at the same scaling ratio of T1 to acquire the position parameter in the infrared thermal image. In the above position setting mode, the user is not necessary to perform manual operation to input the position parameter of the reference image, and during photographing, the thermal imaging device 13 may automatically set the specified position and the specified dimension of the reference image in the infrared thermal image according to the specified position rule, thereby ensuring the standards of the dimension and position of the thermal image of the photographed body and simplifying the operation.

Referring to FIG. 20, the determination of the constituted data of the analysis area is described.

In step S301, if there is a specified designated type of the constituted data of the analysis area is determined. If yes, step S303 is performed, and the control part 10 determines the constituted data of the analysis area according to the specified designated type. If no, step S302 is performed.

In step S302, the analysis area is configured. Via the setting menu as shown in FIG. 9, the corresponding prompt, or the setting bar displaying points, lines, and planes, the users are required to set or select the type of the constituted data of the analysis area.

In step S303, the constituted data of the analysis area is determined.

In the embodiment, since the user selects the photographed body 1 and sets the specified designated type of the constituted data of the analysis area to be “auxiliary 1”, the “constituted data of F1” is determined as the constituted data of the analysis area.

The constituted data of the analysis area may be the default constituted data, may be determined according to the specified designated type of the constituted data combined with the selected body information, may be determined according to the selection of the identity information of the constituted data by the users, or may be the constituted data of the analysis area corresponding to the key according to operation for the specified key. Based on the specified triggering condition, the constituted data of the analysis area corresponding to the triggering condition may be determined, to acquire the analysis area. The way of determining the constituted data of the analysis area based on the constituted data related to the body information may be to select the constituted data for acquiring the analysis area from the constituted data related to the body information or to designate an object from the constituted data related to the body information and to designate the constituted data acquired by processing and/or computing as the constituted data for acquiring the analysis area.

Referring to FIG. 21, the determination processing of the analysis mode is described.

In step S401, if there is a specified analysis mode is determined. If yes, step S403 is performed, and the control part 10 determines the specified analysis mode. If no, perform step S402.

In step S402, the setting menu as shown in FIG. 13 is displayed, and the user is required to set the analysis mode. When the analysis mode to which the analysis area corresponds is set, the constituted data of the set analysis area is related and stored with the analysis mode in the temporary storage part 6, and the newly set analysis area and the corresponding analysis mode are related and stored with the body information in the flash memory 9, such as storing in Table 4, for subsequent use. In addition, the analysis mode (such as minimum, maximum, average) prestored in the thermal imaging device 13 may be selected.

In step S403, in the embodiment, since the adoption of “analysis mode 1” is configured beforehand, the analysis mode (acquired by the analysis mode information of F1) related to the constituted data of F1 is determined.

As the analysis mode related to the analysis area F1 is used, the operation setting trouble of the users on the scene may be avoided, thereby facilitating to perform multiple complicated calculations. In addition, the analysis mode to which the analysis area corresponds may not be related and stored, which may be acquired according to the predetermined analysis mode, such as maximum, minimum, or average of the area units in the analysis area, or may be set in response to setting operation of the users. The analysis mode to which the analysis area corresponds may be related and stored with the constituted data of the analysis area beforehand, may be the analysis mode predetermined in the thermal imaging device 13, or may be the analysis mode set by the users. In addition, the analysis area and the analysis mode of multiple types may be configured at the same time.

Referring to FIG. 22, the setting processing of the position parameter of the analysis area in the infrared thermal image is described.

In step S501, the control part 10 determines if there is a specified position rule. If yes, perform step S503. If no, perform step S502.

In step S502, the setting menu as shown in FIG. 9 is displayed, and the user is required to setting the position rule of the analysis area. After finished, the position determining rule of the analysis area of this type is record to the flash memory 9, as the subsequent default configuration.

In step S503, the position parameter of the analysis area in the infrared thermal image is set. In the embodiment, the position rule of the analysis area is that the type of the main object is benchmark 1, the main object is self-adapted to compute the position parameter in the infrared thermal image according to a centered position of the self-adaptive area Z1, and then the position parameter of the analysis area F1 in the infrared thermal image is determined according to the specified position relation between the analysis area F1 and the contour T1. In a switch state, the type of the main object is auxiliary 1, the main object (the analysis area) is self-adapted to compute the position parameter in the infrared thermal image according to the centered position of the self-adaptive area Z1, and then the position parameter of the contour T1 in the infrared thermal image is determined according to the specified position relation between the analysis area F1 and the contour T1.

In addition, the main object may be acquired by the constituted data except the reference image and the analysis area. That is, the respective position parameter of the analysis area and the reference image is set according to the main object.

During photographing, according to the specified position rule, the position parameters of the reference image and the analysis area in the infrared thermal image are automatically set, and the user is not necessary to input the position parameter of the analysis area by manual operation, thereby ensuring standards of the dimension and position of the thermal image of the photographed body and simplifying the operation. It is not limited thereto. The control part 10 may determine the position parameter of the reference image and the analysis area in the infrared thermal image according to the position parameter inputted by the users via the operation part.

In addition, the designation (the step A02) of the constituted data of the reference image, the position setting (the step A03) of the reference image, the determination (the step A04) of the constituted data of the analysis area, the position setting (the step A06) of the analysis area, and the analysis mode (the step A05) is described according to a certain step sequence, which may be in different sequence of priority according to different embodiments and may not be limited to the processing sequence described in this embodiment.

In the first embodiment, the analysis is always performed, the analysis result is continuously renewed, and the analysis result is displayed when the informing instruction from the users is received. However, it may also be configured that the analysis is performed when the analysis key is pressed or the analysis result may be always displayed and refreshed.

In addition, as shown in the display interface 1703, the position parameter of the reference image may be adjusted to match the thermal image IR1 of the photographed body in the infrared thermal image. Preferably, according to the adjustment of the users, the reference image position setting part and the analysis area position setting part change at least one of the position, dimension, and the rotating angle of the reference image and the analysis area in the infrared thermal image to remain the specified position relation therebetween unchanged. For example, when one of them is adjusted, the other one has the same change according to the adjusted position, dimension, or rotating angle, to remain the specified position relation therebetween unchanged.

According to the above, in the first embodiment, the constituted data of the reference image and the analysis area is designated according to the selection of the body information, thereby facilitating selection of the reference image and the analysis area corresponding to the photographed body. The reference image reflecting the predetermined morphological characters of the photographed body is displayed in the infrared thermal image, and the reference image is as the visual reference of photographing the thermal image of the photographed body, thereby facilitating to acquire the standard infrared thermal image. The constituted data of the reference image and the analysis area is designated from the constituted data with the specified position relation, to allow the set analysis area to be standard and to have the corresponding position with the reference image, thereby allowing the infrared thermal image and the analysis area acquired according to the reference image to be accurate with simple operation. Thus, the aims of the invention may be achieved, and the simple and accurate setting operation of the analysis area may be achieved. According to the analysis mode acquired by the analysis mode information related and prestored with the constituted data of the analysis area, the analysis result is acquired by analysis for the thermal image of the photographed body according to the analysis area, thereby solving the analysis mode setting problem, achieving the simple operation, reducing the skill requirements of the users, improving the photographing speed, being convenient for complicated analysis, and without omitting the photographed body. The analysis difficulty is reduced, and the operation is simple. Thereby, the common users can achieve the better photographing level.

Embodiment Two

In the second embodiment, a thermal imaging device having the same structure with the thermal imaging device 13 in the first embodiment is provided, the flash memory 9 stores the analysis control program which is different from that in the first embodiment, and in response to an analysis instruction of the users, the thermal imaging data that is frozen and displayed, is analyzed, to acquire the analysis result. Further, the flash memory 9 stores the content as shown in FIG. 4 and the configuration as shown in FIG. 13.

Referring to FIG. 23, a control flow is described.

In step B01, the control part 10 continuously monitors if an analysis reference mode is selected. If yes, step B02 is performed.

In step B02, the control part 10 performs determination of the constituted data of the reference image, as shown in the steps S101-S107 in FIG. 18.

In step B03, the control part 10 performs setting processing of the position parameter of the reference image in the infrared thermal image, as shown in the steps S201-S203 in FIG. 19.

In step B04, then, the thermal imaging data acquired via photographing is transferred to the temporary storage part 6.

In step B05, the reference image acquired by the designated constituted data according to the specified dimension set by the position setting part is displayed with the infrared thermal image together according to the specified position, as shown in the display interface 1703.

In step B06, if a user presses the analysis key is determined. If no, return to the steps B04-B05. That is, the image formed by continuous synthesis of the reference image and the infrared thermal image acquired via photographing is displayed. When the user allows the thermal image IR1 of the photographed body and the contour T1 to be in the visual superimposed and matching state as shown in FIG. 17 (the display interface 1704) by adjusting the photographing distance, angle, and image position between the optical part of the thermal imaging device 13 and the photographed body 1, the user presses the analysis key to perform the next step.

In step B07, in response to the operation, the thermal imaging data acquired in the step B04 maintains in the specified area of the temporary storage part 6, or the synthesis image acquired in the step B05 or the infrared thermal image maintains in the specified area of the temporary storage part 6, and the synthesis image (or the infrared thermal image) is frozen.

In step B08, the control part 10 performs determination of the constituted data of the analysis area, as shown in the steps S301-S303 in FIG. 20.

In step B09, the control part 10 performs determination processing of the analysis mode to which the analysis area corresponds, as shown in the steps S401-S403 in FIG. 21.

In step B10, the control part 10 performs setting processing of the position parameter of the analysis area in the infrared thermal image, as shown in the steps S501-S503 in FIG. 22.

In step B11, the analysis is performed, and the acquired analysis result data, such as the maximum temperature of the area units S01, S02 and the temperature difference between S01 and S02, is stored to the specified area of the temporary storage part 6.

In step B12, the analysis result is informed. In the embodiment, the analysis area F1 and the analysis result J17 are displayed on the display part 4, as shown in the display interface 1705. The user may make a judgment according to the analysis result. However, the invention is not limited thereto. They may not be displayed. For example, the analysis result data provided for other devices may be output from the communication I/F 5, or the analysis result may be informed in a phonic mode, and correspondingly the data (may be the sounds to which the analysis result corresponds, or the sounds generated by the sound data to which the character corresponds according to the content of the analysis result) of the sound library may be stored.

In step B13, if the analysis key is released is determined. If yes, perform step B14, and if no, return to the step B12 and continuously display the analysis result.

In step B14, if the analysis reference mode is exited is determined. If no, return to the step B04 and repeat the above steps, and if yes, exit.

According to the above, in the second embodiment, the user allows the infrared thermal image or the synthesis image to be frozen and displayed, in the visual matching state of the reference image and the infrared thermal image, to analysis and display the analysis result, which is different from the first embodiment, thereby ensuring the correction of the analysis. Thus, the analysis and diagnosis during infrared photographing is convenient, the skill requirement of the users is reduced, the photographing speed is improved, the difficulty of the diagnosis is reduced, and the operation is simple.

Embodiment Three

In the third embodiment, a thermal imaging device has the same structure with the thermal imaging device 13 in the first embodiment, and the flash memory 9 stores the content as shown in FIG. 3 beforehand. In the embodiment, when the analysis is needed, the analysis key is pressed to perform the analysis and to inform the analysis result.

To analyze the thermal field distribution of the lower part under the main part of the photographed body, the configuration set via “computing object CD2” is shown in FIG. 24. The computing object is “reference image”, and the computing rule is scaling, computing an inscribed rectangle, or halving for acquiring the analysis area F10. The configuration of “analysis configuration CD2” is shown in FIG. 25 (“others” represents the newly set analysis mode). Further, as shown in FIG. 26, the configuration of the analysis mode is provided for the analysis area F10 acquired via computing, and then the configuration is related and stored in the storage medium.

According to the flow chart in FIG. 27, the control steps in the third embodiment are described. FIG. 28 is a schematic diagram showing display interfaces during a photographing and analyzing process for the photographed body 1 via the contour image T1 and the analysis area F10.

In step C01, the control part 10 continuously monitors if a user selects an analysis reference mode. If yes, perform step C02.

In step C02, the control part 10 performs designation processing of the constituted data of the reference image. Based on Table 3 stored in the flash memory 9, a specified number of the body selecting information is displayed at the specified position of the display part 4. When the user selects “photographed body 1”, the constituted data of T1 is designated.

In step C03, the control part 10 performs determination processing of the constituted data of the analysis area. In detail, according to the configuration in FIG. 24, the constituted data of T1 is as the computing object, and the computing algorithm is “scaling, computing an inscribed rectangle, halving”. Combined with the specified computing parameter, the acquired analysis area F10 is two rectangular frame analysis units, and the constituted data of the acquired analysis area F10, the specified position relation between the analysis area F10 and the reference image T1, the number S01, S02 of the corresponding analysis units are related and stored to the specified area of the temporary storage part 6.

In step C04, the control part 10 performs determination processing of the analysis mode to which the analysis area F10 corresponds. In detail, according to the configuration in FIG. 26, the analysis mode to which the analysis area F10 corresponds is acquired.

In step C05, the control part 10 performs setting processing of the specified position and specified dimension of the reference image in the infrared thermal image. In detail, according to the specified position rule “self-adaptive area Z1, self-adaptively centered”, the position parameter of the reference image T1 in the infrared thermal image is set.

In step C06, the control part 10 performs setting processing of the position parameter of the analysis area in the infrared thermal image. According to the position parameter of the reference image T1 in the infrared thermal image and the relative position relation between the analysis area F10 and the reference image T1, the position parameter of the analysis area F10 in the infrared thermal image is determined.

In step C07, then, the thermal imaging data acquired via photographing is transferred to the temporary storage part 6.

In step C08, the analysis is performed. That is, the thermal imaging data acquired by the photographing part is analyzed to acquire the analysis result, according to the specified analysis mode, based on the analysis area F10 with the position parameter. The image processing part 2 converts the thermal imaging data (the thermal imaging data in S01, S02) determined by the analysis area F10 (S01, S02) to temperature values, and computes according to the analysis mode acquired according to the analysis mode information related to the analysis area F10. The computed analysis result data, such as the maximum temperature of the area units S01, S02 and the temperature difference between S01 and S02, is stored to the specified area of the temporary storage part 6.

In step C09, the reference image T1 is displayed with the infrared thermal image together according to the position parameter. As shown in the display interface 2802, there is greater difference between the thermal image IR1 of the photographed body and the reference image T1. If there is no reference of the reference image, the user fails to subjectively hold the shape of the thermal image IR1 of the photographed body, the imaging position, dimension, and angle in the infrared thermal image. Thus, the focused measuring parts may be omitted and the setting operation of the analysis area is complicated.

In step C10, the control part 10 detects if an analysis instruction is received. If no, step C12 is performed, to determine if the analysis reference mode is exited. If it is not exited, return to the step C07, and in the step C08, the acquired thermal imaging data is analyzed, and the analysis result is stored in the specified area of the temporary storage part 6, to replace the earlier analysis result. Then, in the step C09, the reference image T1 is displayed with the infrared thermal image acquired by the thermal imaging data together. When the acquired thermal image IR1 of the photographed body and the reference image T1 as shown in FIG. 28 (a display interface 2803) achieve the visual superimposed matching state by adjusting, the user presses the analysis key to perform step C11.

In step C11, the analysis result is displayed. As shown in FIG. 28 (a display interface 2804), the analysis result J28 and the analysis area F10 stored in the specified area are displayed (the content capable of being displayed). The user makes the judgment according to the analysis result. However, the invention is not limited thereto. They may not be displayed. For example, the analysis data for controlling other devices may be output from the interface I/F 5. In the display interface 2802 and 2803 in FIG. 28, the analysis area F10 is not displayed, which may be configured to display.

In step C12, if the analysis reference mode is exited is determined. If no, return to the step C07. If the user does not release the analysis key, in the step C11, the analysis result in real time acquired after analyzing the thermal imaging data acquired in the step C07 is displayed. If the user releases the analysis key, the dynamic infrared image and the reference image T1 are displayed. If yes, exit.

According to the above, in the third embodiment, the analysis area is computed and acquired according to the reference image, thereby ensuring the convenience and accuracy of the setting of the analysis area. Thus, the convenient setting of the analysis area is achieved, the skill requirement of the users is reduced, the photographing speed is improved, and the operation is simple.

Embodiment Four

In this embodiment, a thermal imaging device having the same structure with the thermal imaging device 13 as shown in FIG. 1 stores control programs of record processing. Further, the specified record information is as shown in FIG. 29.

Referring to FIG. 30, a flow chart in this embodiment is described.

In step D01, the control part 10 continuously monitors if a user selects an analysis reference mode. If yes, perform step D02.

The step D02 is similar to the steps A02-A12 in the first embodiment, the steps B02-B12 in the second embodiment, or the steps C02-C11 in the third embodiment. The description thereof is left out.

In step D03, the control part 10 determines if there is record instructing operation. The first embodiment is taken for example. When the display part 4 displays the display interface 1705 in FIG. 17, the user presses the record key of the operation part 11 to perform the next step. However, the invention is not limited thereto. Even if there is no specified record instructing operation, the control part 10 may automatically perform step D04, based on the specified record condition. For example, the specified record condition may be that the control part 10 determines the specified time interval, the temperature value in the thermal image exceeds the specified threshold, or triggering signals of other sensors connected with the thermal imaging device 13 are detected.

In step D04, record processing is performed.

The control part 10 as a record part records the specified infrared data with the specified record information, in response to the record instructing operation or according to the specified record condition. Then, perform step D05.

The infrared data is the thermal imaging data acquired by the photographing part (the acquiring part) and/or the data acquired after specified processing for the thermal imaging data acquired by the photographing part. The specified infrared data may be the thermal imaging data (frame) acquired according to signals read by the infrared detector in response to the record instructing operation or at the moment (or the later specified moment) that the specified record condition is satisfied, the specified thermal imaging data (frame) in the multiple frames of the thermal imaging data stored in the temporary storage part 6 in response to the record instructing operation or at the moment (or the later specified moment) that the specified record condition is satisfied, the data acquired after specified processing (the specified processing may be modification, interpolation, pseudo-color, temperature value conversion, pixel reduction, compression, or a combination thereof) for the above thermal imaging data, the record specified number of the multi-frame thermal imaging data, the thermal imaging data (frame) acquired after specified processing for the specified number of the multi-frame thermal imaging data, such as one-frame thermal imaging data acquired after integral calculation for the multi-frame thermal imaging data stored in the temporary storage part 6, or a combination thereof. For example, the infrared data may include the temperature value of each pixel acquired by the thermal imaging data and the image data of the infrared thermal image.

The specified record information as shown in FIG. 29 may one or a combination of the followings:

1) the selected body information (the specified part or all of the body information);

2) the constituted data (or identity information of the constituted data such as a file name) of the designated reference image and/or the position information of the reference image in the infrared thermal image;

3) the constituted data (or the identity information of the constituted data such as a file name) of the designated analysis area and/or the position information of the analysis area in the infrared thermal image;

4) other constituted data (or the identity information of the constituted data such as a file name) having the specified position relation with the reference image or the analysis area and/or the position parameter of the object acquired by the other constituted data in the infrared thermal image, such as, the constituted data acquired by computing and/or processing a designated object and/or the position information of the object acquired by the constituted data in the infrared thermal image;

5) the analysis mode information to which the analysis area corresponds;

6) the analysis result.

When the configuration is as shown in FIG. 13, the corresponding position information is acquired according to the position rule in FIG. 13, and when the configuration is as shown in FIG. 14, the corresponding position information is acquired according to the position rule in FIG. 14. Obviously, when the position parameter of the analysis area is adjusted, the position information to be record may be the position parameter after adjustment.

One embodiment of the relevance record is that the specified record information is as the information attachment of the infrared data with a specified format. In detail, in one embodiment (the first embodiment), in response to the record instructing operation of the operation part 11, the control part 10 controls the infrared detector to read signals to acquire the thermal imaging data, allows the image processing part 2 to perform specified compression for the thermal imaging data or to perform compression after the specified processing such as modification or interpolation for the thermal imaging data, then determines if the temporary storage part stores the specified record information at the specified area, if yes, allowing the specified record information stored at the specified area of the temporary storage part 6 to be related with the compressed thermal imaging data, thus to generate a thermal image file record to the storage card 8, and finally finishes the processing. In addition, the compression may be performed after the specified record information is attached. If no, the thermal image file generated by the compressed thermal imaging data is record to the storage card 8. The record storage medium is not limited to the storage card 8 or the flash memory 9, and may be a network destination communicated via the communication I/F 5.

FIG. 31 is a schematic diagram showing a structure of a thermal image file. The infrared data 3101 is the thermal imaging data acquired by reading from the infrared detector in response to the record instructing operation or according to the specified record condition. According to the configuration in FIG. 29, the information included by the specified record information 3102 is the photographed body 1, the constituted data of T1, the constituted data of F1, the position information of the contour image T1, the position information of the analysis area F1, the analysis mode 1, and the analysis result (the specified analysis result in response to the record instruction, the analysis result at that moment or the specified analysis result after pressing the analysis key in the first embodiment, such as the analysis result of the maximum temperature difference). Other attachment information 3103 may be photographing time.

FIG. 32 is a schematic diagram showing an infrared thermal image IR0 to which the thermal imaging data record when visually matched with the reference image T1 corresponds. The position and dimension of the thermal image IR1 of the photographed body in the infrared thermal image IR0 are standard. The position information of T1 represents the position parameter of IR1 in the infrared thermal image IR0, and the “position information of F1” represents the position parameter of F1 in the infrared thermal image IR0. In addition, if the constituted data to be record is generated, such as recording “benchmark 1 (computing)”, the constituted data to be record may be generated when the constituted data of the reference image is designated, or may be generated when record processing.

In addition, during the relevance record processing, the specified record information may be record to an information file or an index file related to the thermal image file, and the control part 10 may generate the information file or the index file. In addition, a file name of the thermal image file may be generated according to the body information or the identity information of the constituted data. The essence of the relevance record is to record the information that is convenient for the subsequent batch processing analysis. For example, the record of the body information is convenient for classifying the infrared data subsequently, the record of the constituted data and the position information of the reference image is convenient for subsequently setting the analysis area analyzed by batch processing, the record of the analysis area is convenient for subsequent fast batch processing analysis, and the record of the analysis result may reduce the processing time and load of the subsequent batch processing.

In step D05, the control part 10 determines if the user exits from the analysis reference mode. If no, return to the step D02, repeat the above steps, and the user can record for multiple times. If yes, end.

According to the above, since the reference image and the analysis area are used for assisting the photographing of the thermal image of the photographed body, the photographing quality is improved, and the subsequent analysis is facilitated by relating the record and analysis information.

Embodiment Five

In this embodiment, in a thermal imaging device with the same structure of the thermal imaging device 13 in FIG. 1, the flash memory 9 stores the control programs of displaying the reference image display, setting the analysis area, adjusting and analyzing the reference image for the replayed infrared thermal image in a replay mode.

For example, in the replay mode, the infrared data (such as the thermal imaging data acquired by selecting the thermal image file from the storage card 8) to be processed is selected. First, if the infrared data (frame) includes the information related to the analysis mode, such as the constituted data related and stored with the infrared data, the identity information of the constituted data, or the body information, is determined. If yes, the analysis area is determined according to the related information, and then according to the specified analysis mode, the infrared data is analyzed to acquire the analysis result. Otherwise, the reference image reflecting the morphological character of the photographed body may be displayed with the infrared thermal image acquired by the infrared data to be processed together, and the user can observe the visual matching degree of the reference image and the thermal image of the photographed body. If no, the file name, the number, or the thumbnail related to the identity indicator of the constituted data are provided for the users to select. Then, the reference image reflecting the morphological character of the photographed body is displayed with the infrared thermal image acquired by the infrared data to be processed. If the thermal image of the photographed body matches the reference image in visual, the analysis area having the specified position relation with the reference image and the corresponding analysis mode may be allocated for analysis. If the matching degree is not great, the user may adjust the position, dimension, or rotating angle of the reference image to match the thermal image of the photographed body in the infrared thermal image. When matched in visual, the analysis area having the specified position relation with the reference image is determined, and the analysis is performed according to the specified analysis mode.

This invention is not limited to the thermal imaging device with the photographing function. In the embodiment, a thermal image processing device (such as a computer, a personal digital assistant, a display device used in a set with the thermal imaging device with the photographing function) is as an example of a device for analyzing thermal images, for arranging the infrared data (such as the thermal image file).

Embodiment Six

The thermal imaging data in the invention is not necessary to be acquired via photographing. The invention may also be applied to a thermal image processing device receiving and processing the thermal imaging data (thermal image transferring data) from an external part. The thermal image transferring data may be the thermal imaging data (the AD value), the infrared thermal image generated by the thermal imaging data, the compressed thermal imaging data, or the data acquired by compressing the infrared thermal image. In the sixth embodiment, a thermal image processing device 100 is as an example of the device for analyzing thermal images.

FIG. 33 is a block diagram showing a thermal image processing system including a thermal image processing device 100 and a thermal image photographing device 101 connected with each other.

The thermal image processing device 100 includes a communication interface 1, an auxiliary storage part 2, a display part 3, a RAM 4, a hard disk 5, an operation part 6, and a CPU 7 for the overall control connected with the above parts via a bus. The thermal image processing device 100 may be a personal computer, a personal digital assistant, or a display part used in a set with the thermal image photographing device. Based on the control of CPU 7, the thermal image processing device 100 receives the thermal image transferring data output from the thermal image photographing device 101 connected with the thermal image processing device 100 via the communication interface 1.

The communication interface 1 is used for continuously receiving the thermal image transferring data output from the thermal image photographing device 101, such as the thermal image transferring data transferred via a relay device (the thermal image transferring data output from the thermal image photographing device 101 is transferred via the relay device), and may be as the communication interface for controlling the thermal image photographing device 101. In the embodiment, the communication interface 1 includes different kinds of wired or wireless communication interfaces, such as a network interface, a USB interface, a 1394 interface, or a video interface, on the thermal image processing device 100. The auxiliary storage part 2 may be the storage medium such as a CD-ROM or a storage card and the related interface. The display part 3 may be a liquid display or may be other displays connected with the thermal image processing device 100, while the thermal image processing device 100 does not include the display in itself. The RAM 4 is as a buffer storage for temporarily storing the thermal image transferring data received via the communication interface 1 and is as a working storage of the CPU 7 for temporarily storing the data processed by the CPU 7. The hard disk 5 stores control programs and different data used in the control. The structure of the thermal imaging device 13 removing the photographing part 1 is similar to the thermal image processing device 100. The thermal image transferring data that is acquired is also suitable for the embodiment. Therefore, the description of the embodiment is left out.

The CPU 7 performs the function of the image processing part and is used for performing specified processing for the received thermal image transferring data to acquire the image data of the infrared thermal image. The specified processing may be conversion processing to acquire data suitable for displaying and recording, such as modification, interpolation, pseudo-color, synthesis, compression, or decompression. The CPU 7 performs different processing according to different formats of the thermal image transferring data. In one embodiment, when the received thermal image transferring data is the compressed thermal imaging data, the specified processing may be that the CPU 7 decompress the thermal image transferring data received by the acquiring part and performs the corresponding specified processing. In one embodiment, the specified processing after decompressing the compressed thermal imaging data (the thermal image transferring data) may be pseudo-color processing, to acquire the image data of the infrared thermal image. In addition, the specified processing may be specified different processing such as modification or interpolation for the decompressed thermal image transferring data. In other embodiment, for example, when the received thermal image transferring data is the image data of the compressed infrared thermal image, the image data of the infrared thermal image is acquired via decompression. In another embodiment, for example, when the communication interface receives the analog infrared thermal image, the image data of the digital infrared thermal image after AD conversion of related AD conversion circuits is transferred to the temporary storage part 6.

The thermal image photographing device 101 may be a thermal image photographing device of different types, and is used for photographing the photographed body and outputting the thermal image transferring data. In FIG. 15, the thermal image photographing device 101 includes a communication 10, a photographing part 20, a flash memory 30, an image processing part 40, a RAM 50, and a CPU 60. The CPU 60 controls the whole action of the thermal image photographing device 101, and the flash memory 30 stores control programs and different data used in each control. The photographing part 20 includes an optical part, a driving part, a thermal image sensor, and a signal preprocessing circuit, for photographing to acquire the thermal imaging data. The thermal imaging data is temporarily stored in the RAM 50, and then is processed (such as compression) by the image processing part 40 (such as a DSP) to acquire the thermal image transferring data that is output via the communication interface 10. According to difference of design and using aims, for example, the thermal imaging data output by the thermal image photographing device 101 may be the thermal imaging data after specified processing, the image data (the image data of the thermal image generated by the thermal imaging data) of the thermal image, the data after compression by a specified format for the thermal imaging data or the image data of the thermal image, or a combination thereof, which is generally called as thermal image transferring data. In the embodiment, the thermal image photographing device 101 is used for photographing and outputting the thermal image transferring data, and has the function similar to the photographing part 1 of the thermal imaging device 13.

FIG. 34 is a schematic diagram showing the thermal image processing system including the thermal image processing device 100 and the thermal image photographing device 101 connected with each other.

The thermal image photographing device 101 is erected on a detecting vehicle via a cloud ladder and is connected with the thermal image processing device 100 via a special-use cable such as a communication wire or a wired or wireless local area network. The users may watch and monitor the thermal image of the photographed body via the thermal image processing device 100. The thermal image photographing device 101 is connected with the thermal image processing device 100 to form an information recording system in the embodiment, for photographing the photographed body to acquire the thermal imaging data and outputting the thermal image transferring data.

In the invention, the program record on the storage part may be executed to perform the computer (such as a CPU or a MPU) of the system or equipment with the function in the above embodiment, and the computer of the system or equipment may read and execute the program record on the storage part to perform the function in the above embodiment. To achieve the objective, the program acquired from the network or the record medium (such as a computer readable medium) as the storage device is provided for the computer.

To sum up, preferably, the constituted data of the reference image has the specified position relation with the constituted data of the analysis area, and the displayed reference image and the analysis area related to analysis satisfy the specified position relation. The reference image designating part and the analysis area determining part determine the constituted data of the reference image and the analysis area according to the constituted data with the specified position relation. For example, the constituted data therebetween may be determined from the constituted data with the specified position relation prestored in the storage medium. For example, the constituted data of the analysis area may be determined from the constituted data acquired by processing and/or computing a designated object such as the constitute data of the reference image, and the specified position relation between the constituted data acquired by computing and/or processing and the designated object may be determined via the corresponding computing rule or processing rule, or may be defined by the position rule (such as the position parameter is set according to the original dimension and centering of the object acquired by the constituted data) defaulted by the thermal imaging device 13.

Further, the constituted data with the specified position relation may be configured temporarily. For example, the constituted data of the analysis area may be configured according to the specified position relation between the reference image and the analysis area. For example, the analysis area may be set according to the position parameter of the reference image in the infrared thermal image, based on the specified position in the reference image. The specified position may be a coordinate position. The coordinate position may be prestored and related with the constituted data of the reference image, or may be acquired by computing and/or processing the constituted data of the reference image. The analysis area may be set according to the constituted data (such as points, lines, or planes) of the analysis area temporarily configured according to the coordinate position. Therefore, the analysis area may be the analysis area that is set based on the specified position having the specified position relation with the reference image.

Further, when the storage medium is used for storing the constituted data of the reference image, the constituted data of the related analysis area, and the position information of the reference image and the analysis area in the infrared thermal image, the reference image position setting part and the analysis area position setting part are used for setting the respective position parameter of the reference image and the analysis area in the infrared thermal image according to the position information of the reference image and the analysis area in the infrared thermal image.

In addition, the constituted data of the reference image and the analysis area may be determined from the constituted data without the specified position relation. For example, if the specified position relation between the constituted data of the reference image and the constituted data of the analysis area selected from the constituted data related to the constituted data of the reference image or the constituted data related to the same body information may not be prestored, the user may set the position parameter therebetween. Since there is the reference of the reference image, the invention is more convenient than the prior art.

The analysis area set according to the constituted data having the specified position relation with the constituted data of the reference image or the constituted data with the relevance relation is also called analysis area to which the reference image corresponds.

Although the function block in the figures may be realized via hardware, software, or a combination thereof, the function block may be not necessary to be realized in one-by-one mode. For example, one software or hardware unit may be used for realizing multiple function blocks, or multiple software or hardware units may be used for realizing one function block. In addition, the processing and control functions of parts or whole in the embodiments may be realized via a special-use circuit, a general processor, or a programmable FPGA.

Although multiple embodiments of the constituted data of the reference image and the analysis area, position setting of the reference image and the analysis area, determination of the analysis mode, the setting of the synthesis parameter, and the switch setting are described, the users may configure the above processing. However, the invention is not limited thereto. For example, when the thermal imaging device 13 leaves the factory, one or a combination of the above settings may be configured. When the specified designated type of the constituted data of the reference image and the analysis area, the position rule of the reference image and the analysis area, the synthesis parameter, and the analysis mode are configured before leaving the factor, the settings may be performed for the constituted data in the storage medium according to the configuration dispatched from the factory. Otherwise, part items are configured before leaving the factory, and users configure other parts. In the embodiment, the above advantages may be achieved by a series of represented embodiments, and any product performing the embodiment of the invention is not necessary to achieve all of the advantages at the same time.

In addition, in the embodiment, the electric power industry as the scene is taken for example, and different fields of the infrared detection are also applied.
