Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. The specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0027] figure 1 It is a flow chart of the human body action evaluation method provided by the present invention. This embodiment can be applied to the situation of human action evaluation. The method can be executed by the human body action evaluation device. Specifically, the device can perform stable data communication with the depth camera PC. Such as figure 1 As shown, the specific content of the method is as follows:

[0028] The complete length of most professional movements is as many as tens of seconds or even several minutes. For example, the duration of the whole ...

Abstract

The invention provides a method for evaluating human normative actions. Using the human joint skeleton model, the joint skeleton data of the standard action and the comparison action are respectively obtained, and after segmentation, the DTW distance between each segment of the comparison action and the corresponding standard action segment is calculated, and finally the distance of each segment is integrated to obtain the comparison action relative to the standard action. distance. Based on the proposed standard human action evaluation method, the present invention can accurately distinguish the difference between the standard action and the action to be evaluated, and give a quantitative score based on the difference between actions. At the same time, the developed human action evaluation software can perform human action evaluation during the Action guidance and human-computer interaction are convenient for users to carry out interactive scoring tasks such as 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...
