基于空间光传感信息的运动姿态实时跟踪分析与研究

Analysis and research on real-time tracking of motion attitude based on spatial light sensing information

为了排除运动动态性干扰,探讨人体运动下空间光传感信息可作为视觉跟踪特征的可行性,建立起空间三维点与运动姿态对应点的关系,通过计算运动姿态目标点的投影,对摄像机进行标定,根据人体运动动作点的标定,采集到人体运动姿态空间光传感特征,通过提取运动姿态特征,根据人体运动姿态光传感样本点的逆映射原理,重构运动姿态图像,实现运动姿态的实时跟踪。实验结果表明,基于空间光传感信息的运动姿态实时跟踪的横向偏移量还是跟踪准确率方面,都不会受到运动姿态的动态性影响,跟踪方法的准确率可达到1.0,跟踪效率高达0.1,具有更好的稳定性。

In order to eliminate the dynamic interference of motion,this paper discusses the feasibility that the spatial light sensing information under human motion can be used as the visual tracking feature,establishes the rela-tionship between the spatial three-dimensional points and the corresponding points of motion attitude,calibrates the camera by calculating the projection of the motion attitude target points,and collects the spatial light sensing features of human motion attitude according to the calibration of human motion action points,By extracting the motion pose fea-tures and studying the inverse mapping principle of human motion pose optical sensing sample points,the motion pose image is reconstructed to realize the real-time tracking of motion pose.The experimental results show that the lateral offset or tracking accuracy of real-time motion attitude tracking based on spatial optical sensing information will not be affected by the dynamics of motion attitude.The accuracy of tracking method can reach 1.0,and the tracking efficien-cy can reach 0.1,which has better stability.
