Tongue tremor degree evaluation system based on artificial intelligence

Abstract

The invention relates to the technical field of artificial intelligence, in particular to a tongue tremor degree evaluation system based on artificial intelligence. The system comprises: obtaining a mouth key point and a tongue key point through a key point detection unit; acquiring a depth image sequence and an RGB image sequence of the tongue in a set time through an image acquisition unit; extracting an area sequence of the tongue region and a pixel value sequence of the tongue region in a difference image sequence of the tongue region obtained by a frame difference method through a featureextraction unit; correcting the area sequence and the pixel value sequence through a feature correction unit; and inputting the corrected area sequence and pixel value sequence into a time sequence classification network through a tremor degree evaluation unit to obtain the tremor degree of the tongue. The area sequence and the pixel value sequence in the difference image sequence are corrected through the change of the distance between the face of the to-be-detected person and the camera, so that on one hand, the error of the difference image analysis result can be eliminated, and on the other hand, the tongue tremor degree evaluation result can be more accurate.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence, in particular to an artificial intelligence-based tongue tremor evaluation system. Background technique [0002] The tongue is an important organ of the human body. The tongue is connected to the five internal organs through the meridians. The viscera of the human body, the deficiency and excess of qi and blood, and the severity of diseases can all be objectively reflected in the appearance of the tongue. Therefore, traditional Chinese medicine often understands the health status of the body by observing the tongue. [0003] Tongue diagnosis is an important part of TCM diagnosis, and tongue tremor is one of the common symptoms in tongue diagnosis. Tongue tremor is caused by the contraction of tongue muscle fibers. Doctors can obtain some useful information by observing the tongue tremor, which can provide more data reference for the diagnosis of the patient's condition. Therefore...

Problems solved by technology

[0005] In practice, the inventor found that the above prior art has the following defects: in the actual tongue tremor detection scene, the face movement of the person to be tested will cause the movement of the tongue, causing errors in image acquisition, and then the analysis of the collected images have the effect of reducing the accuracy of tongue tremor test results
