Vein recognition system based on thermal imaging

Abstract

A thermal imaging-based Guanmai recognition system, including a non-contact wrist imaging platform based on infrared thermal imaging and a Guanmai extraction algorithm unit; wherein the fixed frame structure of the non-contact wrist imaging platform based on infrared thermal imaging can ensure the measurement of people Every time the wrist enters the imaging area with a fixed posture, the flat laser mark on the platform provides a reference position for aligning the transverse crease of the wrist; the non-contact wrist imaging platform based on infrared thermal imaging will carry the wrist thermal image information of the radial artery The imaging image is sent to the Guanmai extraction algorithm unit to extract the position of Guanmai. The system of the present invention proposes for the first time an algorithm that can automatically identify the location of the Guanmai through thermal imaging image processing, and the recognition of the Guanmai is objectified and digitized. The method of discriminating Guanmai is more feasible in realization.

Description

technical field [0001] The invention relates to the technical field of vein detection, in particular to a system for identifying veins based on thermal imaging. Background technique [0002] In the process of pulse diagnosis and diagnosis in traditional Chinese medicine, the location of Guanmai is extremely important. Whether the Guanmai can be identified is the premise of accurately judging the patient's disease. In TCM pulse diagnosis, the classic biological characteristic points for judging the Guanmai are the radial stalk (called the high bone behind the palm in Chinese medicine) and the transverse wrist crease. Classical ancient books believe that the radial artery on the radial stalk is the Guanmai. Another part of ancient books describes the relationship between the distance between the Guanmai and the wrist stripes with the wrist stripes as dots. Although there are two obvious features, for thousands of years, TCM doctors have only relied on the touch of the hands ...

AI Technical Summary

Problems solved by technology

Although there are two obvious features, for thousands of years, TCM doctors have only relied on the touch of the hand to judge the position of the Guanmai. Due to the difference in the feeling of different people, the judgment of the Guanmai is too subjective and the reproducibility of the Guanmai judgment is too strong. Poor, the repeatability of Guanmai positioning by the same person is also poor, and the accuracy of discrimination cannot be guaranteed

In the existing automatic diagnostic instruments of traditional Chinese medicine, the procedure of locating the Guanmai is also judged by humans, and then the pulse wave probe is placed in the position corresponding to the Cunguanchi. The objectivity of the Guanmai location cannot be guaranteed.
