In the drawings:
Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. It is to be understood that the preferred embodiments described herein are for the purpose of illustration and explanation only and are not intended to limit the present disclosure.
As shown in
The temperature of the various parts of the tongue 300 may be estimated by the brightness temperature image generation component 210, so as to provide doctors with more parameters of the tongue manifestation, which is conducive for doctors to diagnose and treat the subject.
According to an embodiment of the present disclosure, the tongue manifestation detecting device may further comprise a master device, in which the brightness temperature image generation component 210 may be integrated. The master device may comprise a USB interface drive module, an image capture module, an image processing module and an image management module. The image capture module is configured to capture the surface image of the tongue acquired by the image acquisition component 100 and the brightness temperature image of the tongue generated by the brightness temperature image generation component 210. The image acquisition component 100 and the temperature acquisition component 200 are connected to the master device via the USB interface drive module so as to transmit the surface image to the image capture module and transmit the parameters characterized by the temperature of the tongue to the brightness temperature image generation component 210. The image processing module is configured to process the image captured by image capture module.
In the present disclosure, there is no particular requirement for parameters characterized by the temperature of the tongue. For example, the parameters that characterized by the temperature of the tongue can be directly the temperature of the tongue, or the intensity of the infrared emitted from the tongue.
According to an embodiment of the present disclosure, in a case where the temperature parameter of the tongue comprises the intensity of the infrared emitted from the tongue, temperature acquisition component 200 may acquire the intensity values of the infrared reflected at different positions of the tongue, and brightness temperature image generation component 210 can puzzle the intensity values at different positions so as to generate the brightness temperature image of the tongue in which different colors may represent different intensity values.
In the present disclosure, there is no particular requirement on how to acquire the intensity value of the infrared.
For example, the infrared intensity of the tongue can be detected directly. Specifically, the temperature acquisition component 200 stores an initial standard infrared intensity value, and may subtract the initial standard infrared intensity value from an intensity value of the received infrared so as to obtain an intensity value of the infrared emitted from the tongue.
Specifically, the intensity value of the infrared emitted from the tongue may be calculated according to the following formula:
If
i
=If
r
−If
s;
where Ifi represents the intensity value of the infrared emitted from the tongue, Ifr represents the intensity value of the received infrared, and Ifs represents the initial standard infrared intensity value.
In such an embodiment, the temperature acquisition component 200 may be an infrared sensor chip.
The initial standard infrared intensity value represents the infrared intensity value existed in the environment, which is related to ambient temperature. The ambient temperature can be measured in advance before the tongue manifestation is detected by the tongue manifestation detecting device, and then the ambient temperature is converted into the corresponding infrared intensity value. The infrared intensity acquired by the temperature acquisition component 200 comprises the infrared intensity of the tongue and the infrared intensity in the environment. The temperature acquisition component 200 subtracts the initial standard infrared intensity value from the intensity value of the received infrared to obtain the intensity value of the infrared emitted from the tongue.
As another embodiment of the present disclosure, the tongue manifestation detecting device further comprises infrared light sources 600 and 700. As shown in
The tongue itself emits infrared, so the infrared from the tongue consists of two parts: one is the infrared emitted from the tongue and the other is the infrared reflected by the tongue when irradiated by the infrared light source. The temperature acquisition component 200 obtains the intensity of the infrared emitted from the tongue by subtracting the intensity of the infrared reflected by the tongue (substantially equal to the intensity of the infrared emitted from the infrared light source) from the intensity of the received infrared.
In the present disclosure, there is no particular requirement for the specific structure of the infrared light source. For example, the infrared light source may comprise a plurality of infrared light-emitting diodes arranged in an array form. The infrared emitted from the infrared light source may irradiate the surface of the entire tongue such that the temperature of the tongue surface may be completely acquired.
As another embodiment of the present disclosure, the plurality of infrared light-emitting diodes are capable of emitting infrared with different wavelengths alternately. The temperature acquisition component 200 is capable of acquiring the intensity of the infrared reflected by the tongue when irradiated by the infrared of various wavelengths, and the brightness temperature image generation component 210 is capable of generating a plurality of brightness temperature images of the tongue based on the infrared intensity, corresponding to the plurality of the infrared light-emitting diodes, acquired by the temperature acquisition component 200.
A number of different brightness temperature images may be generated under the irradiation of infrared of various wavelengths. The tongue has a different absorption rate for the infrared of different wavelengths. By irradiating the tongue with the infrared of various wavelengths, it is possible to find a wavelength that has the least effect on the absorption rate of the tongue, and thus the brightness temperature images obtained by irradiating the tongue with the infrared of the wavelength is the most clear and accurate.
In the tongue manifestation detecting device provided in the present disclosure, the surface image of the tongue may be acquired by the image acquisition component 100. The surface image of the tongue comprises an upper surface image and/or a lower surface image of the tongue. The doctor can judge the surface state of the tongue of the subject according to the image acquired by the image acquisition component 100 without using the naked eye to observe the tongue of the subject directly, which is more convenient and avoids the influence of the doctor's naked eye on the observation effect.
When the surface image of the tongue comprises the upper surface image of the tongue, the doctor can obtain the state of the coated tongue of the subject. When the surface image of the tongue comprises the lower surface image of the tongue, the doctor can obtain the state of the lingual vein of the subject.
In the present disclosure, there are no particular limits on the structure of the image acquisition component 100. For example, the image acquisition component 100 may comprise a light source 110, a spectroscope 120, a filter lens 170, a controllable lens 160 and an imaging component 130. As shown in
Specifically, the process of the image acquisition component 100 acquiring the original image of the surface of the tongue comprises two steps, namely, an irradiating step and a capturing step. The irradiating step is achieved by the light source 110, the spectroscope 120, the filter lens 170 and the controllable lens 160 together. The capturing step is achieved by the light source 110 and the imaging component 130 together. Specifically, the infrared light emitted from the light source 110 passes through the spectroscope 120 and is divided into two parts, a part of the light is reflected by the spectroscope 120, and the other part of the light passes through the spectroscope 120 to reach the controllable lens 160 and is irradiated on the tongue to be detected to achieve the irradiating step. The light irradiated on the surface of the tongue is reflected by the surface of the tongue to form an interference light having a specific wavelength, the interference light is irradiated on the spectroscope 120 and is reflected by the spectroscope 120 to the imaging component 130 so that the original image of the surface film of the tongue can be obtained to achieve the capturing step.
After the original image is obtained, the original image may be processed using a band-pass filter, through which the contrast ratio of the original image may be adjusted to obtain a more accurate tongue surface image.
Here, the controllable lens 160 refers to a lens in which the focal length is adjustable. The controllable lens 160 may comprise a retractable lens and a servo motor, and the retractable lens can be adjusted by the servo motor to adjust the focal length of the controllable lens 160. The filter lens 170 may filter out unwanted stray light to make the obtained image more accurate.
According to an embodiment of the present disclosure, the image acquisition component 100 further comprises an image delayer 150 and a controllable grating 140 both provided between the imaging component 130 and the spectroscope 120. Further, as shown in
For ease of arrangement, preferably, the angle a between the reflecting surface of the mirror 132 and the straight line where the mirror 132, the image delayer 150, the controllable grating 140 and the spectroscope 120 are located is 45°.
As another embodiment of the present disclosure, the present disclosure also provides a tongue manifestation detecting apparatus comprising the tongue manifestation detecting device according to the disclosure. As shown in
In order to obtain a more comprehensive tongue manifestation parameter by using the tongue manifestation detecting apparatus, firstly, the upper surface image of the tongue 300 can be acquired by the image acquisition component 100, and the parameter characterized by the temperature of the lower surface of the tongue can be acquired by the temperature acquisition component 200 so that the brightness temperature image of the lower surface of the tongue 300 is generated by the brightness temperature image generation component 210. Thereafter, the mounting portion 420 is rotated, in this case, the parameter characterized by the temperature of the upper surface of the tongue 300 can be acquired by the temperature acquisition component 200 so that the brightness temperature image of the upper surface of the tongue is generated by the brightness temperature image generation component 210, and the lower surface image of the tongue 300 can be acquired by the image acquisition component 100.
In the present disclosure, as shown in
According to an embodiment of the present disclosure, at least one of the image acquisition component 100 and the temperature acquisition component 200 may be moved on the mounting portion 420 such that the distance between the image acquisition component 100 and the temperature acquisition component 200 may be changed.
As another embodiment of the present disclosure, the support portion 410 extends in a predetermined direction. Specifically, when the tongue manifestation detecting apparatus is in the operating state shown in
The connector 430 may be fixedly connected to the support portion 410 at one end and may be rotatably connected to the mounting portion 420 at the other end. Alternatively, the connector 430 may be rotatably connected to the support portion 410 at one end and may be fixedly connected to the mounting portion 420 at the other end.
In order to facilitate the acquisition of the tongue manifestation, preferably, as shown in

The slider is movable along the guide rail, and the slider can also be fixed to the mounting portion 420.
