Problems solved by technology

[0004] Since the position of the wearable device may change during the exercise, the collected acceleration and angular velocity will also change accordingly. When identifying the movement information of the athlete based on the acceleration and angular velocity measured after the position change, the movement will be reduced. The accuracy of information identification reduces the accuracy of evaluation results

Abstract

The embodiment of the invention discloses a motion quality evaluation method and device, and a storage medium, and is applied to a motion quality evaluation device, and the method comprises the steps: obtaining the current time when the acceleration information of a motion device is detected to meet a preset starting threshold value, and taking the current time as the center; acquiring acceleration information and angular velocity information of the target moving limb in a preset time period; according to the acceleration information and the angular velocity information, determining multiple pieces of joint angle information of target movement joints intersected with the target movement limbs within a preset time period; matching the multiple pieces of joint angle information with the corresponding relation between preset action information and the joint angle information, and obtaining multiple pieces of action information corresponding to the multiple pieces of joint angle information; and according to a preset joint angle model, carrying out quality evaluation on the multiple pieces of action information, wherein the preset joint angle model is composed of multiple sections of preset joint angle models obtained according to the multiple pieces of preset joint angle information, so that the accuracy of identifying the action information of the sporter and the accuracy of an evaluation result are improved.

Description

technical field [0001] The present invention relates to the field of IT application technology, in particular to a motion quality evaluation method and device, and a storage medium. Background technique [0002] In recent years, in the field of sports, wearable devices have been widely used. By setting sensors in wearable devices, they can detect information such as the breathing and heartbeat of athletes, and analyze the information to evaluate the user's performance during the exercise. Normativeness of action. [0003] In the prior art, the wearable device is mounted on the fixed position of the athlete and the racket, and the acceleration and angular velocity at each fixed position of the athlete's body and the fixed position of the racket are detected when the athlete is moving, and according to the angular velocity and acceleration The motion information of the athlete is identified, so as to evaluate the motion information. [0004] Since the position of the wearabl...
