Abstract

The invention provides a motion function analysis method and electronic equipment, and relates to the technical field of big data processing. The method comprises the following steps: acquiring an action video of a target user executing a preset action instruction, wherein the action video comprises a plurality of video frames; extracting three-dimensional coordinates of skeleton nodes in each video frame, determining an action center frame of the action video based on the three-dimensional coordinates, and extracting a preset number of video frames from the action video based on the action center frame as sample video frames; determining a coordinate matrix of the sample video frame based on the three-dimensional coordinates of the skeleton nodes in the sample video frame, and determining angles at the skeleton nodes based on the three-dimensional coordinates of the skeleton nodes in the sample video frame to obtain an angle matrix; and inputting the coordinate matrix and the angle matrix into a preset detection model to obtain a motion function analysis result of the target user. The exercise function condition of the user can be quickly and accurately evaluated.

Description

technical field [0001] The invention relates to the technical field of image processing, and in particular, to a motion function analysis method and an electronic device. Background technique [0002] In recent years, the number of patients with motor dysfunction caused by stroke has increased significantly. The timely and accurate diagnosis of the degree of motor dysfunction of patients is of great significance for doctors to formulate rehabilitation treatment plans and prevent serious changes in dysfunction. [0003] Scale-based assessment methods are commonly used to assess motor dysfunction in patients. In the evaluation process, the doctor needs to manually check and analyze the patient's movements, and then evaluate the patient's motor dysfunction level according to the patient's movements. This method relies too much on human experience when analyzing patient movements, which not only requires a large investment of medical resources, but also is often difficult to de...
