Cun, guan and chi identification method, terminal and system, medium and computer equipment

Abstract

The invention provides a cun, guan and chi identification method, terminal and system, a medium and computer equipment. The method comprises the steps of obtaining a thermal imaging image of a human wrist, and determining a first mark point corresponding to the radial styloid process of the wrist based on the thermal imaging image; extracting edge contour information between the radial styloid process and the palm and on the two sides of the wrist; determining a wrist cross grain trend straight line based on the edge contour information; acquiring a vertical distance between the first mark point and the wrist cross grain, and determining an inch position abscissa and a ruler position abscissa based on the vertical distance and the first mark point; extracting a radial artery image, and fitting the radial artery image into a linear function; on the basis of the linear function, the horizontal coordinate of the guan position, the horizontal coordinate of the chi position and the horizontal coordinate of the cun position, determining the longitudinal coordinate of the guan position, the horizontal coordinate of the chi position and the longitudinal coordinate of the cun position. therefore, the cun, the guan and the chi are positioned only by using the wrist thermal imaging image and the traditional Chinese medicine one-body cun principle, signal interference is avoided, human subjective interference factors are eliminated, and the positioning precision of the cun, the guan and the chi is ensured.

Description

technical field [0001] The invention belongs to the technical field of vein detection, and in particular relates to a method, terminal, system, medium and computer equipment for identifying inches, guans and rulers. Background technique [0002] The pulse wave contains rich information about the physiological state of the human body. Radial artery pulse wave analysis is considered to be an important means to evaluate the health status of patients in traditional Chinese medicine. In order to understand the general health status of the patient, Chinese medicine divides the distal end of the carpal radial artery into three positions (Cun, Guan and Chi; referred to as Cun, Guan and Chi). Accurate positioning of these three position coordinates is the key to accurate pulse wave collection. premise. [0003] In pulse diagnosis, TCM first takes the posterior segment of the patient's metacarpal as the reference point (known as the radial styloid process in Western medicine), finds...
