Abstract

The invention provides a method for evaluating the standard motion of a human body. The method comprises the steps: obtaining the joint and skeleton data of a standard motion and a comparison motion through a human body joint and skeleton model, carrying out the independent segmentation of the standard motion and the comparison motion, calculating the DTW distance between each segment of the comparison motion and the corresponding standard segment, and finally integrating the distances of all segments to obtain the distance between the comparison motion and the standard motion. The method provided by the invention can accurately distinguish the standard motion and a to-be-evaluated motion, and gives a quantified score based on the difference between the motions. Developed human body motionevaluation software can carry out the motion guide and man-machine interaction in an evaluation process of a human body motion, thereby bringing convenience to a user for carrying out the scoring interaction of the entertainment, learning and professional analysis.

Description

technical field [0001] The invention belongs to the technical field of human motion analysis, and relates to a method for automatically evaluating human body normative actions. Background technique [0002] In our social life, there are many human body movements that have strict norms and routines, such as dance, martial arts, gymnastics, etc. Whether it is a professional sports competition or a mass sports activity, it is essential to evaluate the normativeness of the action completion in these events. At present, the scoring of standardized actions in sports competitions is mainly done by referees, and the scoring results are easily affected by the referee's subjective factors. On the one hand, it is difficult to provide a large number of referees with certain professional skills in mass sports activities, and on the other hand, it is difficult to guarantee the authority and objectivity of amateur referees. Therefore, for such sports with standardized movements, a system...
