ABSTRACT

Based on the integrated application of intelligent wearable devices, this research obtains multi-dimensional real-time data in the movement process, obtains the human skeleton point data based on Openpose and carries out standardization preprocessing, extracts different posture features of the human body in combination with the geometric features of the skeleton space, and proposes an improved multi criteria decision tree intelligent algorithm theory of motion model and health evaluation system. On this basis, the statistical analysis and advantage comparison of multivariable motion data are carried out. Finally, the evaluation system of sports basic movement teaching based on multi criteria side optimization decision-making algorithm is established, and the functional design of each module is introduced. The research found that boys' upper limb strength and girls' cardiopulmonary endurance are the most important basic physical qualities that affect students' performance. The influence of lower extremity explosive force and cardiopulmonary function on boys' performance is only lower than that of upper extremity strength. The effect of girls' lower limb fast running ability on their performance is only inferior to that of their cardiopulmonary function; While increasing the strength of upper and lower limbs, boys can significantly improve the passing rate by properly improving cardiopulmonary endurance training. Proper improvement of girls' fast running ability and their cardiopulmonary endurance can significantly improve the passing rate of girls. And the motion intelligent recognition system in this study can overcome the self-occlusion of joint points when observing actions from a fixed perspective in a single perspective dataset.
