Design of Police Physical Training System Based on Kinect Motion Capture

运动捕捉系统骨骼关节点坐标数据稳定性较差,导致系统的跟踪精度低、训练效果差。设计基于Kinect运动捕捉的警察体能辅助训练系统。通过安全管理模块、训练计划模块、训练监控模块、资料查询模块和训练考评模块实现警察体能辅助训练系统功能,利用Kinect运动捕捉技术获取警员在体能训练过程中的骨骼关节点坐标数据,基于Holt双指数平滑算法平滑处理骨骼关节点坐标数据,增强数据稳定性。实验结果表明骨骼关节点坐标数据的稳定性提高,系统跟踪精度高、训练效果好。

The poor stability of the coordinate data of bone joint points in the motion capture system leads to the low tracking accuracy and poor training effect of the system.This paper designs police physical fitness training system based on Kinect motion capture.Through the security management module,training plan module,training monitoring module,data query module and training evaluation module,the function of the police physical training system is realized.Kinect motion capture technology is used to obtain the coordinate data of skeletal joint points of police officers in the process of physical training,and Holt double exponential smoothing algorithm is used to smooth the coordinate data of skeletal joint points,so as to enhance the stability of data.The experimental results show that the stability of bone joint point coordinate data is improved,the system has high tracking accuracy and good training effect.
