| Objective:Constitution is an inherent and relatively stable characteristic of human beings,which depends on the combined action of congenital and acquired factors.The Yellow Emperor’s Classic of Internal Medicine classifies the human physique into five types based on the characteristics of the five elements of wood,fire,earth,gold and water,i.e.,the five forms of the human physique,which play a vital role in health maintenance and the treatment of untreated diseases.Many modern studies have explored the psychological characteristics of the five forms of the human physique,but still lack analysis of the morphological characteristics of the human body.The face,as the first part of the diagnosis,can reflect the overall state of the human body,and the facial characteristics of the five forms are different,so it is important to identify the five forms of the human physique by extracting and analyzing the morphological characteristics of the face.Even so,the current research on the facial features of five-shaped people still lacks a unified classification standard,which cannot realize the objectivity and measurability of TCM facial diagnosis and brings certain difficulties to the identification of the physical constitution of five-shaped people in TCM.At the same time,the technical limitations also restrict the development of facial recognition of five-shaped people to a certain extent.Therefore,this study conducts theoretical research on the doctrine of TCM physical constitution,physical constitution classification methods,the classification of five-shaped human physical constitution and the identification of five-shaped human physical constitution,proposes the extraction and analysis of five-shaped human facial features using face recognition methods,summarizes the laws of five-shaped human facial features,explores the physiological and pathological characteristics of five-shaped human,provides a technical interface for the development of intelligent identification technology of five-shaped human physical constitution and the establishment of a TCM face feature recognition database,and further exploits the technical interface of five-shaped human facial features recognition.It will provide a technical interface for the development of the intelligent recognition technology of five-shaped human body and the establishment of the database of TCM face feature recognition,and further exploit the application value of five-shaped human body in TCM diagnosis.Methods:This study used the methods of literature review and theoretical research to explore the classification and characteristics of the physique of the five shaped people in "The Yellow Emperor’s Classic of Internal Medicine".Starting with the concept,classification,characteristics,and identification of physique,the facial and facial features of the five shaped people were determined.After that,the ASM model algorithm in computer image recognition technology is used to automatically mark the key feature points of 301 face images,and the distance between the feature points is calculated using the distance formula between two points.After that,the facial index method is used to calculate the ratio.Through quantitative methods,the facial and facial features of the five shaped person are ultimately obtained,thereby achieving computer automatic identification of the five shaped person’s physique.At the same time,clinical research methods were used to collect the physical appearance,personality,psychology,and physiological and pathological characteristics of the study subjects,and analyze the basic and pathological characteristics of the physique of the five shaped people from the perspective of shape and spirit,providing a basis for disease risk prediction.Result:1.General data statistics:① The physical distribution of the five shaped people in TCM:93 wooden shaped people,accounting for 30.8%;54 fire
