Method and device for evaluating human body actions based on skeleton key points

Abstract

The invention discloses a method and a device for evaluating human body actions based on skeleton key points, and relates to the technical field of computers. A specific embodiment of the method comprises the steps of collecting an action picture of a target main body in a human body movement process; extracting skeleton key point coordinates of the action of the target main body according to theaction picture; and inputting the skeleton key point coordinates into a pre-trained evaluation model to evaluate the action of the target main body, the evaluation model being used for evaluating theaction of the human body on the basis of a human body posture azimuth angle calculated by the skeleton key point coordinates. According to the method, human body action evaluation can be performed based on the skeleton key points and the human body posture azimuth angle, and the evaluation method is simple, high in efficiency and accuracy and good in user experience; and meanwhile, the problem that the evaluation result is not objective and accurate enough due to artificial subjective judgment of an evaluator is solved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for evaluating human body movements based on bone key points. Background technique [0002] In the fields of sports competition and health, it is necessary to recognize human body movements in order to evaluate the standard situation of movements. The early common evaluation method is that the evaluator observes the human body movement with eyes, and then compares it with the movement standard pattern to give a score; at the same time, the evaluator holds the camera to extract the video, and then saves it with a screenshot of the video for future reference. This method not only wastes manpower and material resources, but also makes the evaluation results not objective and accurate enough due to subjective reasons. [0003] Therefore, with the development of computer technology, most of the current methods are to model the movement standard data, and...
