Research on MEMS sensor-based police physical fitness assistance training system.

In order to address the problems of lack of methods and low efficiency of coaching in traditional police physical fitness-assisted training systems, this paper proposes a Micro-electromechanical system (MEMS) sensor-based sports assistance training system. Using the MEMS sensor's working principle, the system's hardware design is completed through the design of the logical framework of the physical fitness-assisted training system and the design of the physical fitness-assisted training sensor. At the same time, the trainer's arm motion posture angle is calculated by extracting the body motion trajectory features and combining them with the Kalman filter method, and then the trainer's posture estimation algorithm is designed, and finally, the software design of the system is completed, to realize the design of the motion-assisted training system. The experimental test results show that the MEMS sensor-based police physical fitness-assisted training system can increase the number of assisted training methods and improve coaching efficiency, thus greatly improving the performance of the police physical fitness-assisted training system. The system designed in this paper is of great significance to the promotion of motion capture technology and its application in the field of police physical fitness-assisted training.
