Problems solved by technology

[0004] The purpose of the present invention is to provide a multi-spectral facial physiological signal acquisition system and method, aiming at solving the problem that the existing face diagnosis instrument only uses white LED as the light box light source, which can only obtain the subject's face color, but cannot obtain the subject's face color. The problem of the patient's pulse wave information

Abstract

The invention discloses a multi-spectrum facial physiological signal acquisition system and method. A function of acquiring pulse waves is added on the basis that an existing facial diagnosis instrument can acquire facial colors. An annular LED lamp band capable of emitting multiple light rays is designed as a light source, a driving hardware and control functions of the lamp source are matched, and then pulse wave information existing in capillaries at different depths can be detected, so that qualitative thinking that only facial color is analyzed in the traditional Chinese medicine facial diagnosis instrument is broken. Meanwhile, pulse waves are acquired at the same time, and qualitative analysis is carried out on heart rate, blood oxygen content, heart rate variability, pulse pressureand the like of a tested person through pulse wave information, so that the problems that only a white light LED is adopted as a lamp box light source in the existing face diagnosis instrument, onlythe face color of a subject can be acquired, and pulse wave information of the subject cannot be acquired are solved.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine facial diagnostic instruments, in particular to a multispectral facial physiological signal acquisition system and method. Background technique [0002] Facial diagnosis in TCM "inspection diagnosis" is a method of diagnosing the health status and disease of the observed person by observing the distribution and changes of facial color, which has important clinical significance. The general face diagnosis instrument is designed to solve the problem that the complexion diagnosis by doctors will be affected by subjective factors, ambient light, etc. Therefore, the existing Chinese medicine face diagnosis instruments, whether based on direct light or diffuse reflected light, are generally The subject's face was imaged using a white LED as the light box light source. However, there are the following defects in the prior art: Generally, the diagnosis of traditional Chinese medicine...
