Description

Technical Field

[0001] The present invention relates to the technical field of traditional Chinese medicine diagnosis and treatment, and specifically to an early prediction and diagnosis method for digestive system diseases based on traditional Chinese medicine constitution identification. Background Technique

[0002] Traditional Chinese medicine constitution identification is a method of comprehensively analyzing an individual's physical characteristics, physiological manifestations, psychological state, etc. to determine their constitution type. Traditional Chinese medicine constitutions are mainly divided into peaceful constitution, qi deficiency constitution, yang deficiency constitution, yin deficiency constitution, phlegm-dampness constitution, damp-heat constitution, blood stasis constitution, qi stagnation constitution, and special endowment constitution. Among them, the peaceful constitution is an ideal constitution state, and the remaining eight constitutions represent certain problems in the body. Since ancient times, traditional Chinese medicine has attached great importance to the study of constitutions, believing that constitutions determine the susceptibility of the human body to certain etiologies and the trend of disease development and transformation. Therefore, through traditional Chinese medicine constitution identification, personalized conditioning plans are formulated according to the constitution type, including dietary conditioning, acupoint massage, traditional Chinese medicine conditioning, etc., in order to achieve the purpose of preventing and treating diseases.

[0003] Currently, in the process of traditional Chinese medicine constitution identification, generally, doctors diagnose the constitution through pure vision and touch. This not only has a large workload but also has the problem of inaccurate diagnosis due to decreased energy. Moreover, because traditional Chinese medicine constitution identification can only detect the constitution state of the corresponding patient and analyze the possible disease risks in a certain system of their body based on the constitution state, it cannot further predict and diagnose the early stage of the disease. Therefore, patients may not actively undergo examinations, resulting in the continuous development of the disease and being unfavorable for early treatment. Summary of the Invention

[0004] The purpose of the present invention is to provide an early prediction and diagnosis method for digestive system diseases based on traditional Chinese medicine constitution identification to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the present invention provides the following technical solution: An early prediction and diagnosis method for digestive system diseases based on traditional Chinese medicine constitution identification, including the following steps:

[0006] 1) Establish a diagnostic file for the individual undergoing the interview, then collect constitution identification data through the scale identification method and the traditional four diagnostic methods respectively, and conduct constitution identification with reference to the knowledge graph of traditional Chinese medicine constitution identification;

[0007] 2) Take pictures of the face and tongue of the person undergoing the interview through a photographing device, then conduct pulse feeling and body posture observation and detection on the person undergoing the interview. The photographed images of the face and tongue are segmented into multiple pictures, and then the segmented face images and tongue images in different regions are matched with the constitution imaging states in the knowledge graph of traditional Chinese medicine constitution identification to confirm that the face and tongue states of the person undergoing the interview conform to the corresponding constitution information;

[0008] 3) The interviewer fills in the scale questions, enters the interviewer's personal information, and then generates a corresponding constitution report for the interviewer in combination with the examination results of the traditional four diagnostic methods;

[0009] 4) Provide the constitution report, confirm the health status of the interviewer's digestive system after matching the interviewer's constitution type, and judge the risk level of the interviewer's digestive system health;

[0010] 5) According to the constitution information identified by the interviewer, the doctor takes out the acupuncture tools and acupuncture the corresponding digestive system acupoints of the interviewer. During the process, the doctor continuously observes the facial expressions and body postures of the interviewer;

[0011] 6) When the interviewer shows abnormal facial and body postural changes during acupuncture of different digestive system acupoints, suspect the corresponding digestive system diseases and issue a predictive diagnosis report, through which the interviewer can further seek medical examinations.

[0012] In a further embodiment, the traditional Chinese medicine constitution identification knowledge graph is used to construct a traditional Chinese medicine constitution identification model. The specific methods of the tongue image segmentation and face image segmentation are as follows:

[0013] 1) Take images of the interviewer's face and tongue positions. After extracting the images of the interviewer's face and tongue, then perform tongue image segmentation on the face and tongue images;

[0014] 2) Preprocess and divide the images of the segmented face and tongue information, and extract the features of each part after the face and tongue image segmentation;

[0015] 3) After extracting the features of different parts of the face and tongue, use the constructed traditional Chinese medicine constitution identification model to perform feature comparison to confirm the constitution type corresponding to the face and tongue;

[0016] In a further embodiment, the specific methods of the preprocessing and sample processing of the face and tongue information are as follows:

[0017] Preprocessing: Use edge detection to eliminate the front and back backgrounds of the pictures of the segmented tongue image and segmented face image, separate the tongue from the shooting background, and prevent the influence of non-tongue pixels on the comparison of the segmented tongue image and segmented face image;

[0018] The sample processing is specifically calculated by the following formula:

[0019] f(i+u,j+v)=(1-u)(1-v)f(i,j)+u(1-v)f(i+1,j)+(1-u)vf(i,j+1)+uvf(i+1,j+1)

[0020] Among them, f(i,j) represents the pixel value of the original image at position (i,j), and u and v are the decimal offsets of the target pixel relative to the original pixel in the x-axis and y-axis directions, respectively.

[0021] In a further embodiment, after the segmented tongue image and segmented face image obtained after the face and tongue image segmentation are preprocessed and sample processed, the tongue portion of the tongue image is processed to obtain 640x640 pixels.

[0022] In a further embodiment, the segmented tongue image and segmented facial features of the face and tongue are to divide the facial image into forehead area, ear area, eye area, nose area, mouth area, chin area and cheek area, and the image taken of the tongue is divided into tongue body area, tongue coating area and tongue back area.

[0023] In a further embodiment, the digestive system acupoints are specifically: Cheek-cartilage point, Dicang point, Tiantu point, Tanzhong point, Zhongwan point, Zusanli point, Neiguan point, Zhongwan point, Tianshu point, Guanyuan point, Liver-shu point, Pancreas-shu point and Spleen-shu point.

[0024] In a further embodiment, the risk level of the digestive system health is specifically divided into: low risk, medium risk, high risk and severe risk;

[0025] The risk level is determined based on the physical fitness value obtained from the patient's examination. The standard for determining the value is based on the similarity between the patient's physical fitness and the corresponding TCM physical fitness type. The patient's physical fitness is more inclined to the corresponding physical fitness type, thereby confirming the risk level.

[0026] In a further embodiment, the facial features and tongue features of the patient are collected using a high-definition camera, the pulse is taken by a doctor and a pulse taking device, and the body posture observation is performed by the doctor instructing the patient to perform corresponding body movements, and the doctor observes and judges the completion of the patient's movements.

[0027] In a further embodiment, the traditional four examinations include inspection, auscultation, questioning and palpation, wherein inspection is performed by collecting the facial and tongue features of the patient through a camera and the doctor's observation of the patient's body posture for diagnosis, auscultation is performed by the doctor's listening to the sound of the patient's speaking and the smell emitted from the patient's breathing and coughing, questioning is performed through questions on a scale that the patient needs to fill in, and palpation is performed by feeling the patient's pulse and the doctor feeling the patient's pulse and palpating the pulse for diagnosis.

[0028] In a further embodiment, the questionnaire filling options are divided into five items, namely: always, often, sometimes, rarely and never, and the corresponding filling options are 5, 4, 3, 2 and 1 for scoring.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. In the present invention, by using a photographing device to photograph and collect the face and tongue of the person being questioned, and then performing point-to-point morphological data matching on the images of the face and tongue with the traditional Chinese medicine constitution identification knowledge graph, efficient feature extraction and comparison are achieved, and then the characteristic states of the face and tongue are obtained for judging the constitution type of the person being questioned. The process is efficient and intelligent, reducing the workload and difficulty of doctors and improving the accuracy of constitution identification.

[0031] 2. In the present invention, by asking the person being questioned with a scale and performing the traditional four diagnostic methods, and performing constitution identification based on the physical sign states obtained above, the application of traditional Chinese medicine constitution identification in the preliminary judgment of early digestive system diseases and the prevention of digestive system diseases according to their constitution types can be realized.

[0032] 3. In the present invention, when the traditional Chinese medicine constitution identification shows a constitution type with digestive system diseases, through the detection method of traditional Chinese medicine acupuncture and continuous pulse feeling, the direction of digestive system diseases can be further diagnosed. When performing acupuncture, the doctor inserts the needle into the corresponding acupoints of the digestive system, and then observes the facial expressions and body postures of the person being questioned to confirm the direction of digestive system diseases, providing a more specific disease diagnosis direction for the person being questioned.

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Embodiment 1

[0038] Please refer to Figures 1 - 3 , this embodiment provides a method for early prediction and diagnosis of digestive system diseases based on traditional Chinese medicine constitution identification, including the following steps:

[0039] 1) Establish a personal diagnostic file for the medical interview, then collect constitution identification data through the scale identification method and the traditional four diagnostic methods respectively, and conduct constitution identification with reference to the knowledge graph of traditional Chinese medicine constitution identification;

[0040] 2) Take pictures of the face and tongue of the interviewee through a photographing device, then conduct pulse feeling and body posture observation on the interviewee. The taken pictures of the face and tongue are segmented into multiple pictures, and then the segmented face images and tongue images in different regions are matched with the constitution imaging states in the knowledge graph of traditional Chinese medicine constitution identification to confirm that the face and tongue states of the interviewee conform to the corresponding constitution information;

[0041] 3) The interviewee fills in the scale questions and enters his own information, and then combines the examination results of the traditional four diagnostic methods to generate a corresponding constitution report for the interviewee;

[0042] 4) Provide the constitution report, confirm the health of the interviewee's digestive system after matching the constitution type of the interviewee, and judge the risk degree of the health of the interviewee's digestive system;

[0043] 5) According to the constitution information identified by the interviewee, the doctor takes out the acupuncture tools and acupuncture the corresponding digestive system acupoints of the interviewee. During the process, the doctor continuously observes the facial expressions and body posture changes of the interviewee;

[0044] 6) When abnormal facial and body posture changes occur to the interviewee during acupuncture of different digestive system acupoints, suspect the corresponding digestive system diseases and issue a predictive diagnosis report, and the interviewee can further go to the doctor for examination through this report.

[0045] Use the knowledge graph of traditional Chinese medicine constitution identification to construct a traditional Chinese medicine constitution identification model. The specific methods for the analysis of segmented tongue images and segmented face images are as follows:

[0046] 1) Take pictures of the face and tongue positions of the interviewee. After extracting the face and tongue images of the interviewee, then conduct tongue image segmentation on the face and tongue images;

[0047] 2) Preprocess and divide the images of the segmented face and tongue information, and extract the features of each part after the segmentation of the face and tongue;

[0048] 3) After extracting the features of different parts of the face and tongue, use the constructed traditional Chinese medicine constitution identification model to conduct feature comparison to confirm the constitution type corresponding to the face and tongue;

[0049] The specific methods for the preprocessing and sample processing of the face and tongue information are as follows:

[0050] Preprocessing: Use edge detection to eliminate the front and back backgrounds of the pictures of the segmented tongue images and segmented face images, separate the tongue from the shooting background, and prevent the influence of non-tongue pixels on the comparison of the segmented tongue images and segmented face images;

[0051] The sample processing is calculated as follows by the formula:

[0052] f(i + u, j + v) = (1 - u)(1 - v)f(i, j) + u(1 - v)f(i + 1, j) + (1 - u)vf(i, j + 1) + uvf(i + 1, j + 1)

[0053] Among them, f(i, j) represents the pixel value of the original image at the position (i, j). u and v are the fractional part offset values of the target pixel relative to the original pixel in the x-axis and y-axis directions respectively. By magnifying the segmented tongue image and segmented face image after segmentation, part extraction is performed and background miscellaneous items are removed. Subsequently, pixel processing and image quality enhancement are carried out, so that it is more convenient to extract feature points from the captured facial image and tongue image, and the effectiveness and accuracy of feature extraction are improved.

[0054] After the segmented tongue image and segmented face image obtained by segmenting the facial and tongue images are preprocessed and sample processed, the part of the tongue in the tongue image is processed to obtain 640x640 pixels. The segmented tongue image and segmented face image of the face and tongue divide the facial image into the forehead area, ear area, eye area, nose area, mouth area, chin area and cheek area, and the image captured by the tongue is segmented into the tongue body area, tongue coating area and tongue back area.

[0055] The collection of the facial features and tongue features of the person being questioned is realized by using a high-definition camera. The pulse diagnosis is completed by the doctor and the pulse diagnostic instrument. The postural observation is carried out by the doctor instructing the person being questioned to perform corresponding limb movements, and the doctor observes and judges according to the completion situation of the person being questioned's movements. Here, the high-definition camera is connected to the computer device, and a comparison library is established in the computer device through the knowledge graph of traditional Chinese medicine constitution identification. Therefore, after the facial and tongue images are captured, the segmented images are used, and then the segmented images are processed to remove noise, so as to obtain high-definition segmented part photos, which are compared with the comparison library of the knowledge graph of traditional Chinese medicine constitution identification in the computer system, so as to quickly obtain the corresponding digestive system disease features and corresponding constitution features, and then complete the rapid identification of traditional Chinese medicine constitution.

[0056] Traditional four diagnostic methods include inspection, auscultation and olfaction, interrogation, and palpation. In inspection, the facial and tongue features of the person being questioned are collected through a camera device, and the doctor observes the person's body posture for diagnosis. In auscultation and olfaction, the doctor diagnoses by listening to the person's voice and the odor emitted from breathing and coughing. Interrogation is carried out through the scale questions that the person being questioned needs to fill in. Palpation is through feeling the pulse and the doctor's palpation of the person being questioned. The risk level is judged according to the physical constitution value obtained from the examination of the person being questioned. The judgment standard of the value is based on the similarity matching degree between the physical constitution of the person being questioned and the corresponding traditional Chinese medicine physical constitution type. By detecting that the physical constitution of the person being questioned is more inclined to the corresponding physical constitution type, the risk level can be confirmed. The risk levels of digestive system health are specifically divided into: low risk, medium risk, high risk, and severe risk. Through the traditional four diagnostic methods and combining with the physical condition of the person being questioned obtained from the scale, the traditional Chinese medicine physical constitution of the person being questioned can be quickly and efficiently identified and confirmed. Then, according to the impact of the physical constitution type on the digestive system and quantifying the physical constitution data, it is specifically quantified as the number of disease characteristics reflected in the face, tongue, pulse, and scale related to the digestive system. When the number is greater than the diagnostic threshold of early digestive system diseases, it indicates that there are early diseases in the digestive system. And according to the number of these characteristic points and the number of disease characteristics, when it is greater than the set risk level threshold, the risk level of digestive system diseases can be judged, and further examinations are needed to confirm or rule out the condition.
