Abstract

The invention relates to a hand function accurate evaluation system and method based on image recognition, and the method comprises a hand motion video obtaining module which is used for obtaining a hand motion video of each testee in a preset time period; a video processing module which is used for carrying out hand key point labeling on the hand motion video so as to determine space coordinate position data of key points in the hand motion video; a data analysis module which is used for calculating a change curve of each finger of the left hand and the right hand relative to the movement distance along with time by taking the left palm bottom position and the right palm bottom position as reference points according to the space coordinate position data of the key points in the hand movement video, and converting the change curve of the relative distance along with the time into characteristic parameters required for evaluating the hand movement function; and a result storage and output module which is used for storing the characteristic parameters required for evaluating the hand functions and constructing and outputting a hand movement function database.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a system and method for accurately evaluating hand function based on image recognition. Background technique [0002] The hand is an important carrier for human beings to complete information communication, emotional communication, and perform the most delicate, flexible and complex motor functions in daily life. Studies have shown that the function of the upper limbs accounts for 60% of the functions of the whole body, while the functions of the fingers account for 90% of the functions of the upper limbs. Hand dysfunction will cause patients to be unable to take care of themselves to a certain extent, which not only brings inconvenience to the patient himself, but also brings burden to the patient's family members. At present, the incidence of hand dysfunction caused by hand trauma, stroke or other neurodegenerative diseases such as cervical spondylosis is increasing. ...
