Action assessment system

Abstract

An embodiment of the invention provides an action assessment system. The system comprises at least one visual sensor, a wireless action capture unit and an assessment device, wherein the at least one visual sensor is used for receiving a collection instruction, collecting position information of a preset target joint at a specified position point and sending the collected position information to the assessment device; the wireless action capture unit is used for receiving the collection instruction, collecting motion information of a preset limb part and sending the motion information to the assessment device; and the assessment device is used for sending the collection instruction to each visual sensor and each wireless action capture unit every a preset time period, receiving and fusing the position information and the motion information to obtain pose information, and comparing the obtained pose information with pose information in a standard action information frame to obtain a comparison result. By applying the technical scheme provided by the system, the accuracy of the comparison result is improved.

Description

technical field [0001] The invention relates to the technical field of recognition, in particular to an action evaluation system. Background technique [0002] In daily study and work, you can learn standard movements through movement training, for example, learning opera movements and dance movements. In the process of movement training, the traditional method is to conduct on-site evaluation and guidance based on the naked eyes and experience of the teacher or coach, and the evaluation results are subject to a certain degree. But at present, there has been a method that can be evaluated by the movement evaluation system to give guidance to the movement trainer. This method is objective and the guidance has a high accuracy rate. [0003] Existing motion evaluation systems generally include evaluation equipment and multiple wireless motion capture units, and multiple wireless motion capture units are fixed on the preset body parts of the motion trainer for collecting motion...

AI Technical Summary

Problems solved by technology

However, for the existing motion evaluation system, if the motion is relatively complex and the motion range is relatively large, the wireless motion capture unit will loosen or fall off, which directly leads to inaccurate motion information collected by the corresponding wireless motion capture unit

And if in order to prevent the wireless motion capture unit from loosening or falling off, the wireless motion capture unit is bound tightly on the person's body, which will make the motion trainer feel uncomfortable, which will affect the motion trainer's action

Therefore, it is difficult to collect more accurate motion information through the wireless motion capture unit, which directly leads to inaccurate attitude information obtained according to the collected motion information, which in turn leads to inaccurate final comparison results

[0005] In view of this, the existing action evaluation system has the problem of inaccurate comparison results that needs to be solved urgently
