Health status assessment method and health status assessment system using the same

The present invention relates to home health assessment technology, and more particularly to a health state assessment method that utilizes facial color change to determine a state of health and a health status assessment system using the method.

According to the fact that the birth rate of newborns is decreasing year by year, and the medical technology and environmental quality are increasing day by day, people's life expectancy is gradually prolonged. This has led to Taiwan's gradual progress into an aging society. In order to effectively manage and assess the health status of the family, the technology of home health care It is developing vigorously. At present, there are quite a few related patents. I will not repeat them here. In general, we mainly use sphygmomanometers and heart rate monitors to detect general health information of the human body, and then transmit them to the computer equipment records or network. The management center of the medical institution at the remote end has achieved the effect of health management and care.

Secondly, Chinese medicine has the theory that "the disease must be observed, and the color must be observed." That is, the diagnosis method of "seeing diagnosis" is performed before the medical examination. Usually, the color change of different parts of the face is observed first, and the individual is based on the individual. Professional experience to determine whether the corresponding organs in the body have problems, for example, the nasal roots correspond to the heart area, the cheeks correspond to the large intestine area, the cheeks near the eyes correspond to the small intestine area, and the human middle corresponds to the bladder and uterus, if the color of the cheeks is Different or more discolored, that is, there may be problems in the large intestine, and further diagnosis of the disease in the large intestine is needed.

In other words, if you can check the health status of your individual at any time through the traditional Chinese medicine, you can get medical treatment before the disease has not occurred or the condition is not serious. It is of great help to the treatment of the disease. However, the accuracy of the diagnosis will be affected by the professional experience of the Chinese medicine practitioners. The evaluation criteria are less objective, let alone the average person who cannot sensitively observe and remember the changes in the face every day.

Therefore, if the theory of traditional Chinese medicine can be applied to the related technologies of home health care, it will have a very good health care effect, but there is no such technology so far, and such as the Republic of China Invention No. 592663 "to identify irises The patents and devices for access control and health control and health consultation management are shown in the patent. They use the method of capturing the iris image of the eye and the five-wheeled theory of Chinese medicine theory to test the human health. It is better to directly observe different parts of the face. The color change changes to judge the function state of a specific organ to be objective and extensive.

The main object of the present invention is to provide a health state assessment method and a health state assessment system using the same according to the theory of traditional Chinese medicine, by capturing image color values of various regions of the face at different times and healthy faces. The color difference of the regional image changes to assess whether the body organ function is abnormal. It can objectively obtain the function of Chinese medicine, remind the doctor to diagnose and provide medical reference, and have the effect of simple health management and care.

The reason is that, in order to achieve the aforementioned purpose, the present invention provides a health The Kang state evaluation method includes at least the establishment of a color reference value: capturing a facial image and establishing a color reference value of the facial image when healthy; sampling: capturing most color detection values of the facial image at different times; calculating the difference : calculating a color difference value between each color detection value and a color reference value; evaluating: determining whether the specific organ function of the body is abnormal by the change of each color difference value.

Further, a step of color correction is further included to eliminate color errors caused by the photographing device.

Further, the face is divided into a plurality of regions, and then the color reference values of the images of the regions of the face at the time of health are established.

Further, the captured facial image is an RGB color mode that needs to be converted to a device independent color space mode, such as the CIE L*a*b* (CIELAB) color mode.

Further, the color difference value between each of the color detection value and the color reference value is obtained.

Further, a region threshold value may be defined, and when each of the color difference values is greater than the region threshold value, a problem occurs in the corresponding organ function.

Further, in the step of evaluating, an overall threshold value may be defined, and when the sum of the color difference values of the various regions of the face is greater than the overall critical value, it represents a problem of physical health.

Further, in the step of establishing a color reference value and sampling, the captured facial image is captured in an environment with a standard light source.

Further, the facial image is captured in a light box with a D65 light source. Shoot inside.

In addition, the present invention further provides a health state evaluation system using the method, comprising an image capturing device, comprising an image capturing area and an image capturing device disposed in the image capturing area; a control unit connecting the The image capture device includes a data storage module for storing image data captured by the image capture device, and an operation module connected to the data storage module for calculating a color difference value of the image data.

In the following, a preferred embodiment of the present invention will be described in detail with reference to the drawings. First, referring to the first embodiment, the health state evaluation method 100 of the preferred embodiment of the present invention is coordinated. The theory of traditional Chinese medicine (the different parts of the face can reflect the function state of different organs in the body), using the digital camera to capture the image of the face and the color of the face image to determine whether the body function is abnormal, the first step is color Correction 110: Color error caused by the color spectrum analyzer or color measurement management software to eliminate the digital camera. Since the color value of the image captured by the digital camera may deviate from the true color value observed by the eye, in order for the image data to accurately represent the color value of the human face, it is necessary to perform a color correction procedure on the digital camera.

Color spectrum metering for color correction is as follows: measuring with a color spectrum meter PR650 under a specific light source (such as D65, A standard swatch of A light source, then take the standard swatch with a digital camera, and then compare its color image data (RGB value) with the three stimuli value XYZ measured by the color spectrum meter to find the digital camera RGB system. A 3 × 3 matrix is converted with the tristimulus value XYZ to be converted.

The color measurement management software performs color correction as follows: The color measurement management software is used as a digital camera to create an ICC profile (ICC profile) advocated by ICC (International Color Consortium). The ICC profile of this digital camera can be made from the color management software of the standard swatches, that is, the color characteristics of the digital camera under the framework of processing color management via a computer. The data is pre-stored in a color profile, and in this color management system, the color profile of the digital camera is transformed from the input data space to the device independent color space (like CIEXYZ, CIELAB, etc.) Color space), thus available in CIELAB color space independent of the digital camera color space RGB.

The above methods for performing color correction of a digital camera by a color spectrum meter or a color measurement management software are conventional techniques and will not be described in detail herein.

The second step of the present invention establishes a color reference value 120: in an environment with a standard light source, such as a light box with a D65 light source, which divides the face into several regions, and uses a digital camera to capture images of various regions of the face when healthy. Then establish a color reference for the images of various regions of the face when healthy value. The facial image captured by the digital camera is RGB color mode (three primary color light mode), which needs to be converted to CIE L*a*b* (CIELAB) color mode, L* stands for Lightness, and a* stands for red and green. , b* stands for yellow and blue. Converting RGB color mode to CIE L*a*b* (CIELAB) color mode is a technique of conventional image processing. The technical connotation and operation method are not described here. The front face can be divided into the nose, the nose, the nose, the cheeks, the cheeks near the eyes, the cheeks near the nose, the person and the lips and the chin. The nose is the spleen area of the Chinese medicine theory. Corresponding to the liver area, the nasal roots correspond to the heart area, the cheeks correspond to the large intestine area, the cheeks near the eyes correspond to the small intestine area, the cheeks near the nose correspond to the stomach area, the human middle corresponds to the bladder, the uterus, and between the lips and the chin. Corresponding to the fine room area.

The third step of the present invention is to sample 130: to capture images of various regions of the face at different times (such as daily) to obtain a majority of color detection values. As mentioned earlier, the face image of the RGB color mode must also be converted to the CIE L*a*b* (CIELAB) color mode.

The third step of the present invention calculates the difference 140: calculating the color difference ΔE*ab of each of the color detection value and the color reference value ( ), its calculation is as follows:

Usually △E*ab≦3( When people's eyes are difficult to distinguish.

The final step of the present invention is to evaluate 150: first define a region threshold, such as ΔE*ab ( ) = 3, by each color difference (ΔE*ab) ( The change determines whether the function of the specific organ of the body is abnormal, that is, when each color difference is greater than the regional threshold (such as ΔE*ab=3), it represents a problem with the corresponding organ function. It is also possible to define an overall critical value. When the sum of the color differences of the various regions of the face is greater than the overall critical value, it represents a problem of physical health. If the sum of the color differences of the various regions of the face is lower than the overall critical value, it indicates that the health condition is good.

Therefore, the features and effects of the health state assessment method 100 of the present invention are as follows: the present invention cooperates with the Chinese medicine facial color to reflect the change of organ function, and uses the image of each face of the face taken during health as a color reference value. Then, under predetermined environmental conditions (such as a light box with a D65 light source), the image of each area of the face is captured every day to obtain different color detection values, and then the color detection values are compared with the color reference values to calculate the color. Difference, if the color difference of a certain area of the face is greater than the regional critical value (such as △E*ab=3), it means that the organ corresponding to this area may have functional problems and needs attention, for example, if the nasal root area The difference in color is greater than the regional threshold, indicating that the function of the heart may cause problems and should be diagnosed as soon as possible, as shown in the attachment.

Since Chinese medicine practitioners rely heavily on the professional experience of physicians and must cooperate with actual diagnosis to properly assess the function of body organs, it is impossible for people to remember the facial color of each day to detect whether the changes in the function of body organs are different. Status assessment method 100 is available for comparison every day撷 The color detection value and the color reference value are taken to observe whether the color difference value exceeds the regional critical value as a criterion for evaluating whether the specific organ function of the body is abnormal, and whether the sum of the color difference values of each area of the face is greater than The overall critical value is used as a criterion for assessing whether there is a problem with physical health. The assessment method is very objective. You can observe and prevent it in advance to achieve the effect of normal health care.

As can be seen from the above, the present invention further provides a health assessment system 10, as shown in the second diagram, comprising an image capture device 12, a control unit 14, and a display device 16. The image capturing device 12 includes an image capturing area 22 and an image capturing device 24, the image capturing area 22 is equipped with a standard light source, such as the light box having the D65 light source, and the image capturing device 24 is a coefficient camera. The control unit 14 is a conventional computer system, and is connected to the image capturing device 24 to receive image data, including a data storage module 26, an operation module 28 and a control module. a module (not shown), the data storage module 26 is configured to store image data, and the computing module 28 can be a computer program for performing color difference between the color detection value and the color reference value. In the calculation, the display device 16 is a display device such as a screen, and is connected to the control unit 14 for displaying each of the color detection value, the color reference value, and the color difference value.

The health status assessment system 10 can also connect to the medical information database of the Chinese medicine practitioner through the Internet for the initial diagnosis and subsequent medical care of the Chinese medicine practitioner.

In summary, the method and system for assessing the state of health provided by the present invention, according to the theory of traditional Chinese medicine, utilizes the method of capturing images of various regions of the face in different periods, and the color values of the images of the faces of the face and the face of the healthy face. The color values of the images in each area are compared and calculated to obtain the color difference value. The abnormality of the body organ function can be evaluated by the change of the color difference value. The function of the traditional Chinese medicine can be objectively obtained, and the diagnosis and treatment are required. Provide reference for medical treatment, with the effect of simple health management and care; the reason is that the invention does meet the requirements of the invention patent and submits an application according to law.
