Real-time identification of motion attitude based on laser three-dimensional detection technology

针对传统方法对人体运动姿态进行辨识时不能满足实时监测的要求的问题,提出激光三维探测技术的运动姿态实时辨识方法。首先根据激光三维成像技术原理,创建人体姿态的动态模型,采用四元数对动态模型中的坐标进行转换,得到人体运动的实际姿态角;构建人体空间直角坐标系,根据姿态角和解算方法对坐标系中各轴的峰值变化进行分析,得出人体运动姿态的辨识结构;在此基础上创建出实时监测平台,实现对人体运动姿态的远程实时监控。通过仿真实验验证,所提方法能够不受运动加速度的影响,准确实时地辨识出人体的运动姿态,说明该方法具有实际应用性,可为相关工作提供一定的参考价值。

Traditional methods cannot meet the requirements of real-time monitoring when identifying human motion attitude.Therefore,a real-time identification method of human motion attitude based on laser three-dimensional detection technology is proposed.The principle of laser three-dimensional imaging technology is put forward.According to this technology,the dynamic model of human body attitude is created.The coordinates of the dynamic model are transformed by quaternion,and the actual attitude angle of human body motion is obtained.The human body space rectangular coordinate system is constructed,the peak changes of each axis in the coordinate system are analyzed according to attitude angle and calculation method,and the identification structure of human motion attitude is obtained.On this basis,a real-time monitoring platform is created to realize remote real-time monitoring of human motion attitude.The simulation results show that the proposed method can identify human motion attitude accurately and realtime without the influence of acceleration.It shows that the method has practical application and can provide some reference value for related work.
