The Enrollment Applications, incorporated by reference above, describe devices for the enrollment of packages. In some instances, a package is placed on a surface, e.g., a stationary surface. A camera is located in a fixed position (e.g., on an extension arm above the package) relative to the surface. The camera obtains images of the package and processes the images to determine some or all of the dimensions of the package.
In some cases, it would be desirable to determine the dimensions of a package (or other object) using a device that is not fixed in position relative to the package. For example, in many cases it would be advantage to have a hand held device that could be carried by a user, and used to capture the dimensions of objects. It would be advantageous if such a handheld device could accurately and quickly determine the dimensions of the object without regard to the orientation of the object relative to the device.
The inventors have realized that the devices, systems, and methods described herein may be used to conveniently acquire the dimensions of an object, e.g., using a handheld device. In some embodiments, depth images of the object are obtained, e.g., using in infrared three dimensional (3D) camera. The depth images are processed to determine dimension data.
In some embodiments, the object to be dimensioned is known to be of a general shape (e.g., a hexahedron or, more specifically, a cuboid), and the image processing is designed to leverage this shape information to more accurately and/or efficiently determine the dimensions of the object based on the depth images.
For example, in some embodiments, a depth image is processed to find a “hot spot” that likely corresponds to a corner of a cuboid object. As detailed herein, based on the identified “hot spot”, and using the fact that three orthogonal faces of the cuboid meet at this corner, the depth image can be processed to identify segments of the depth image corresponding to the faces. The resulting segmented image can then be used to accurately and efficiently determine the dimensions of the object.
In one aspect, a method of determining dimension information indicative of the dimensions of an object is disclosed, the method including: receiving a depth image of the object; and processing the depth information. The processing includes: determining a region of interest (ROI) in the image corresponding to a corner of the object; generating local normal information indicative of local normals corresponding to points in the image; generating, based at least in part on the ROI and the local normal information, object face information indicative of an association of points in the image with faces of the object; and determining the dimension information based at least in part on the object face information.

In some embodiments, the identifying object points includes identifying points in the image corresponding to points located in planes passing within a threshold distance from the location of the corner. In some embodiments , generating object face information further includes: generating segmentation information indicative of a distribution of the object points; and estimating the location of the faces of the object based on the segmentation information.
In some embodiments, estimating the location of the faces of the object based on the segmentation information includes: determining an orthogonal triplet of axes based on the segmentation information.
In some embodiments, determining the dimension information based at least in part on the object face information includes: projecting each of the object points onto one of the three axes; and determining the dimension information based on the projection.

Various embodiments may include any of the features described above, alone or in any suitable combination.
In some embodiments, the position of the dimension capture device 101 is not fixed relative to the object 200. For example, as shown, the dimension capture device 101 is a hand held unit. The hand held unit allows a user to move about, and to quickly and conveniently capture the dimensions of objects in various locations and orientations. In some embodiments, the object 200 is stationary. In some embodiments, the object 200 may be moving, e.g., on a conveyor belt.
Although
In some embodiments, the IR 3D camera includes an infrared illuminator (e.g., an LED or laser projector) and sensor, such as a CMOS sensor. The infrared lilluminator projects near-infrared light and the sensor receives the returning light. In various embodiments, the IR camera is insensitive or substantially insensitive to changes in ambient lighting in the visible spectrum.
In some embodiments the infrared illuminator illuminates the field of view of the camera with a structured light pattern. The depth image can then be generated using suitable techniques known in the art, including depth from parallax techniques and depth from focus techniques. Examples of such techniques may be found, e.g., in U.S. Pat. No. 8,050,461, issued Nov. 1, 2011, the entire contents of which are incorporated by reference in their entirety.
In some embodiments, the IR 3D camera may be of the type available from PrimeSense Ltd. of 104 Cambay Ct. Cary, N.C., which interprets 3D scene information from a continuously-projected infrared structured light. For example, one PrimeSense 3D scanner, marketed as Light Coding, employs a variant of image-based 3D reconstructions. Light Coding works by coding the scene volume with near-IR light. The IR Light Coding is invisible to the human eye. A sensor, such as a CMOS image sensor, reads the coded light back from the scene. PrimeSense's system on a chip (SoC) is connected to the sensor and executes a parallel computational algorithm to decipher the received light coding and produce a depth image of the scene. The sensor is generally unaffected by ambient lighting changes, especially those in the visible portion of the spectrum.
In some embodiments, the IR 3D camera includes an infrared laser projector and a sensor such as a CMOS sensor. The infrared laser projector transmits infrared light onto the object and measures its “time of flight” after it reflects off an object, similar to sonar technology. The infrared laser projector pulses infrared light towards the object at a frequency of, e.g., several megahertz. The pulses are reflected back, captured by the sensor 606 and turned into a distance measurement to determine depth or height of an object.
In some embodiments, the IR 3D camera encodes information in the infrared light patterns emitted by the infrared laser projector, the infrared laser projector emits the light onto the object, and the sensor captures and analyzes the deformation of the patterns resulting from the encoding of the infrared light. The deformations in the light patterns are caused by object's presence. Detecting and using the deformations of the infrared light patterns can help generate finer image of the object's three-dimensional texture.
In various embodiments, any other suitable sensor for generating a depth image may be used.
In addition to a sensor for obtaining depth images, the sensor unit 110 may include other types of sensors. For example, the sensor unit 110 may include a conventional camera used to capture two dimensional (2D) images of the object 200. Any suitable camera can be used, e.g., a digital color or black and white camera. The 2D camera may be used to capture a single image, multiple images, a video stream, etc., of the object 200. In some embodiments the conventional camera may be a component of the IR 3D camera. For example, when the IP 3D camera includes a 2D IR camera used in conjunction with a structured light projector, the 2D IR camera may be used as a conventional cameral by selectively switching off the structured light projector.
In some embodiments, the sensor unit 110 may include other types of sensors including, e.g., a bar code reader, a distance senor (e.g., a sonic or light based distance sensor), a light level sensor for detecting ambient lighting conditions, a radio frequency identification (RFID) device (e.g., for reading an RFID tag on the object 200), etc. In various embodiments the sensor units may include one or more illumination devices for illuminating the object 200. In some embodiments the sensor unit may include one or more aim assisting devices, e.g., a laser aiming beam used to aid in aiming the dimension capture device at the object 200.
As shown, the dimension capture device 101 is a handheld unit including a handle 112 that can be gripped by the user. Although a “ray gun” shape is shown, it is to be understood that ay suitable form factor may be used. For example, in some embodiments the device 101 may have a form factor similar to that used for a cellular phone or a tablet computer device.
In some embodiments, the device 101 need not be hand held, but can instead be integrated into a unit worn by the user, e.g., as eye wear, a head piece, a shoulder mounted piece, etc.
The device 101 may include one or more control devices 114. As shown, the control devices are in the form of push buttons, however any other suitable controls may be used. For example, various embodiments may include a keyboard, a touch screen, a switch, etc. The control devices 114 may control any aspect of the system 100. For example, the control devices 114 may be used to control the functioning of the sensor unit 110, the communication between the dimension capture device 101 and the processor 102, etc.
In some embodiments, the dimension capture device 101 includes a display unit 116. The display unit 116 may include any suitable display. For example, the display unit may include one or more indicators, e.g., to indicate successful capture of dimensions of the object 200. In some embodiments, the display unit 116 may include a screen that can display images of the object (e.g., based on the depth or other images captured by the sensor unit 110) or other information (e.g., dimension information output from the processor 102).
In various embodiments, processor 102 receives a depth image of the object 200 from the sensor unit 110 of the dimension capture device 101 and processes the image to determine the dimensions of the object 200. As described above, in typical embodiments, the position of dimension capture device 101 is not fixed relative to the object 200. Thus, the dimensions of the object 200 must be determined without the benefit of pre-existing information about the relative position or orientation of the dimension capture device 101 and the object 200.
Regardless of location and orientation, the point of the cuboid 1 that exhibits the smallest depth measure 3 is very unlikely to be anything else but one of its corners. This 3D location (referred to herein as a “hot spot”) 4 is particularly interesting because of the two following properties. First, as the point with minimal depth measure, it is particularly easy to find from the raw depth data provided by the sensor 2. The point, being nearest corner of the cuboid, must belong to all of the cuboid's visible faces.
In a variety of applications, a dimensioning problem of the type described above presents a number of technical challenges. Provided with a depth image composed of a point cloud of depth measurements, one must isolate the object of interest from the rest of the scene. Furthermore, as the depth measures can reveal no more than half of the item, one also needs to extract relevant geometrical features in order to measure it. These challenges fall under the general category of data segmentation as they aim to label each datum with either the object or the geometrical feature it belongs to.
For many types of known sensors, depth images may be noisy. For instance, some sensors known in the art provide less than a 10 mm precision in its estimation of depth. Accordingly, one must account for this noisiness before one considers any derivatives of these measures for the purpose of geometric feature extraction. Depth data also has the tendency to be sparse. In many cases, single frame's worth of depth data will exhibit areas in the field of view where the depth is simply unknown.
In various applications, the problem may be too complex and computationally expensive for conventional techniques. As is recognized in the art, turning a depth image point cloud into a small, manageable and meaningful set of polygons is not an easy problem in general. Approaches employing iterative techniques such as random sampling consensus (RANSAC) or region growing may be memory and/or computationally prohibitive. Similarly, 3D generalizations of 2D image processing techniques such as the Hough transform are generally also memory and/or computationally prohibitive.
In various embodiments, the techniques described herein may be used to overcome the technical challenges noted above. In some embodiments, as detailed below, a process is used that restricts its attention to features that are located around or coplanar with a single 3D location, the hot spot 4. The algorithm then uses a mixture of local and distributed features in order to detect the object's proper orientations and isolate it from the scene.
In step 402 the depth image is processed to determine the hot spot of the object to be dimensioned. As used herein, a depth image is an image for which each pixel value conveys a distance between the sensor 2 used to obtain the image, and a corresponding point in the field of view of the sensor. In some embodiments, selection is based on the data point (or region of points) that exhibits the smallest depth value in a portion of the depth image, e.g., within a central zone of interest in the sensor's field of view. As discussed previously, this hot spot point 4 almost certainly corresponds to a corner of a cuboid object 1.
In step 403, the raw depth image is processed to determine the local normal corresponding to points in the image. These local normals can be determined based on taking a spatial derivative of the depth data, using techniques known in the art. An example can be found Murillo, Feature Track and detection at available at http://w3.impa.br/˜francisc/IProc/report.html.LyXconv/report.html (accessed May 11, 2012).
In some embodiments, e.g., where the raw depth image is noisy, a filter or other processing may be applied to the depth image prior to determining the local normals. For example, a low pass spatial filter may be applied to the raw image data.
In step 404, object segmentation is performed based on the hot spot determined in step 402, and on the local normals information generated in step 403. As illustrated in
The distribution 9 (shown in
In step 405 an orthogonal triplet corresponding to the cuboid object 1 is determined. Ideally, if the object were a perfect cuboid and the normal measures were error-free the distribution would end up consisting of three orientations, each one corresponding to the projection of one of the cuboid's visible faces onto the sensor's image plane. Realistically though, one is more likely to get a few clusters. Additionally, only two faces might be visible.
For example,
One does do know however that the cuboid's faces are orthogonal with respect to one another. Accordingly one may estimate which triplet of orthogonal orientations best explains the distribution gathered, as shown in
Note that in the case of only two visible faces,
Referring back to
In an additional step, the dimensions of the object, or related information, may be output.
A local normals module 603 processes the depth image to determine the local normals at points on the image. In some embodiments, the local normals module operates with a pre-processing module 604 that processes the depth image prior to determining the local normals. For example, in some embodiments, the pre-processing module 604 applies a low pass spatial filter to the depth image.
A segmentation module 605 receives hot spot information from the hot spot module 602 and local normals information from the local normals module 603. The segmentation module 605 processes this information to identify local normals that are likely to correspond to points on the object to be dimensioned. In some embodiments, the segmentation module produces a 2D distribution of the identified normals. As described above, clusters in the 2D distribution will each correspond to a respective face of the object.
An orthogonal triplet module 606 estimates which triplet of orthogonal orientations best explains the distribution produced by the segmentation module. This orthogonal triplet is the estimation of the cuboid's proper axes. The orthogonal triplet may be determined by any suitable method, e.g., a constrained least squares optimization technique.
A dimensioning module 607 performs a final segmentation and dimensioning. The data points identified by the segmentation module 605 as potentially belonging to the object of interest are projected onto the axes estimated by the orthogonal triplet module 606. The length of these projections provides basis for the estimation of the object's three dimensions.
The processor 102 may include an output 608 for outputting dimension information.
Various embodiments of the devices, systems, and methods described herein may include one or more of the following features.
The system 100 may include a PSD (Postal SecurityDevice), e.g., included in the processor 102
The system 100 may use available information (e.g. from an intranet or internet connection, an integrated global positioning system device, etc.) to establish the location of the object 200.
The system 100 may include a secure “black box” data recorder for audit and control purposes. This capability can be remotely accessed (e.g. via an intranet or internet connection).
The system 100 may include cryptographic capabilities, e.g., consistent with export regulations.
User management and tokens may be supported. Departmental accounting may be provided. SAP codes may be supported.
In various embodiments, work flow systems integration and support for manufacturing systems will be available. Dashboard facilities with remote access will be supported. Automatic integration with dispatch centers will be supported. Embedded wireless broadband will be available. Ability to read full size checks and bill payment forms may be included. Ability to capture signed documents may be included.
In various embodiments, various peripheral devices may be supported including but not limited to: card readers, printers, postal label printers, interactive customer display, pin Input devices, and keyboards.
As noted above, in some embodiments, the dimension capture device 101 includes a conventional camera (e.g., an RGB camera). For example, the conventional camera may be used to acquire an image of the object 200. This image may be associated with the determined dimensions of the object or any other suitable information related to the object. In some embodiments, a conventional image of the object can be processed to identify text or other markings on the object. These markings can be processed using optical character recognition (OCR) techniques. In general, conventional images of the object may be processed using any of the techniques described in the Enrollment Applications incorporated by reference above.
The conventional camera may be used for other purposes, e.g., for conveniently acquiring information related to the dimensioned object. For example the cameras could be used to acquire information found on customs forms, bills of sale, packing lists, etc. and/or customer payment information. In general, the camera may be used to implement any of the techniques described in the Enrollment Applications.
In some embodiments, information determined using the conventional camera may be used to verify or refine dimension information generated using the depth camera. For example, in some applications, a depth image may be relatively noisy. In some such cases, once an object has been identified and dimensioned using the noisy depth image, this information may be used to identify the corresponding object in the less noisy conventional camera image (e.g., using information regarding the relative orientations of the two cameras). Any suitable machine vision techniques (e.g., edge detection techniques) may then be applied to the object in the conventional image to provide supplementary information regarding the object (e.g., a refined or higher precision estimate of one or more of the object's dimensions).
It is to be understood that while the examples above have been directed to dimension capture applications, the processing techniques described herein may be used in any suitable application. For example, these techniques may be implemented in a machine vision system, e.g., for locating and/or determining the size of objects.
In some embodiments, the techniques described herein may be used to process data other than depth images where pixels in the image correspond to a distance from a sensor to an object in the sensor's field of view. For example, the processing techniques described herein may be applied for segmenting other types of images including, e.g., medical images, seismic images, etc.
In general, the depth images may be generated using any suitable type of sensing including optical sensing (e.g., parallax type schemes of the type described above, RADAR, LIDAR, sonic range finding, etc.).
In some embodiments, the techniques described above maybe be used to determine the dimensions of an object in real time or substantially real time That is, in some embodiments the dimension data is output less that 5 seconds, less than 1 second, less than 0.1 seconds, or less than 0.01 seconds after the depth image is initially acquired. In some embodiments, the dimension information is output substantially simultaneously with the image acquisition.
In some embodiments, the dimensions of the object are determined with an accuracy of +/−10 cm, 5 cm, 1 cm, 0.1 cm, 0.01 cm, 0.001 cm or better. In some embodiments, this accuracy can be obtained using depth images with accuracy no better than +/−10 mm.
In some embodiments, the processing techniques described above may be applied to previously acquired image data. For example processor 102 may receive images from a database of stored images rather than directly from the dimension capture device 101.
While the examples above describe the processing of a single depth image of an object, it is to be understood that in some embodiments multiple images maybe used. For example, multiple sparse depth images acquired within a short time of each other (e.g., short enough that motion of the dimension capture device 101 is not an issue) may be combined to generate a composite image. This composite image may then be processed as described above.
In some embodiments, each of several images can be separately processed to determine the object dimensions. The repeated dimension measurements can then be combined (e.g. averaged) to produce an improved dimension estimate. In some embodiments, the multiple dimension measurements may be used to estimate the accuracy of the measurements. For example, if the dimensions found in the multiple measurements differ from each other by more than a threshold amount, a error warning may be output indicating a possibly faulty result.
In the examples presented above, the dimensions of an object are determined solely from a depth image without the use of any predetermined information about the location or orientation of the object. However, in some embodiments, such information, when available, may be used to supplement, aid, or confirm the dimensioning process.
For example, in applications where the object is expected to to lie flat on the ground, the dimension capture device may include a sensor (e.g., a MEMs accelerometer or gyroscope, or other inertial sensor) that provides some information about the orientation of the device 101 with respect to the ground. This information could be used to indicate a likely error if the depth image processing identifies an object in an unlikely orientation (e.g., standing on edge relative to the ground).
As will be understood by those skilled in the art, the devices, systems and techniques described herein may be used in a variety of applications including, but not limited to: parcel enrollment, chain of custody management, supply chain management. The dimension capture functionality may be used for 3D modeling or printing, computer generated image applications, surveying applications, etc.
Although the examples above have been directed to dimensioning box shaped objects. However, as will be understood by those skilled in the art in view of the present disclosure, the techniques described herein may be adapted in a straightforward fashion for use with other types of polyhedronal objects (e.g., pyramidal objects, octahedron objects, etc.)
In some embodiments, techniques of the types described herein may be used to capture the dimensions of objects having one or more curved surfaces. For example, in some embodiments, the dimensions of a cylindrical object (e.g., a barrel shaped container) may be obtained. For such an object, the depth image may be processed to indentify a “hot spot” corresponding to the closet point on the object. Local normals may then be found in the region of the depth image at or near this spot. A cylindrical surface may be indentified as corresponding to a region where all of the normals, if extended, converge onto a straight line (i.e., the cylindrical axis of the cylindrical object). The radius of the object may then be determined as the distance from the identified surface to the cylindrical axis. The length of the cylinder may then be determined in a straightforward fashion, e.g., by identifying the flat faces associated with the top and bottom of the cylinder using techniques of the type described above.
A similar approach may be used for dimensioning spherical objects. For such an object, the depth image may be processed to indentify a “hot spot” corresponding to the closet point on the object. Local normals may then be found in the region of the depth image at or near this spot. A cylindrical surface may be indentified as corresponding to a region where all of the normals, if extended, converge onto a point (i.e., the center of the spherical object). The radius of the object may then be determined as the distance from the identified surface to the center point.
In various embodiments, the devices provided herein may operate in multiple modes for detecting and dimensioning objects in multiple shape classes. In some embodiments, the mode may be user selected. In other embodiments, the device may switch between modes automatically, e.g., by searching for a best fit for a given object.
The various embodiments described above described identifying and dimensioning a single object within a depth image. However, in some embodiments, the techniques described herein may be applied to identifying and dimensioning multiple objects within a single depth image or a set of depth images. In some embodiments, this may be accomplished in an iterative fashion. For example, a first object (e.g., the closest relevant object) may be identified and dimensioned. The area in the depth image corresponding to this object may then be blanked or otherwise removed from consideration. The process in then repeated, identifying and dimensioning a second object, and then blanking the depth image region corresponding to the second object. The process may continue until all objects in the image (or a scene composed of multiple images) have been identified and dimensioned. Note that in various embodiments, other information related to the objects may be collected (e.g., OCR of printed labels, barcode information, RFID tag information, etc.) and associated with the captured dimension information.
A multiple object dimension capture process of the type described above may be particularly useful in application where in is desirable to obtain an inventory of objects in a particular defined region (e.g., a room).
In various embodiments, other suitable display arrangements may be used. In some embodiments, a conventional camera image may be used instead of the depth image. In some embodiments, the device may include a projector (e.g., a laser projector) that displays information (e.g., measured dimensions) directly onto or near the object 200.
