【摘要】：人体重心是反映人体形态结构和质量分布特征的基本参数,本文探讨利用体感交互设备获取较为精确的重心位置。首先借助体感交互设备Kinect获取人体实时的关节点坐标数据,构建适合于体感交互设备Kinect的人体重心计算的环节模型,结合人体重心计算方法中力矩合成法的改进算法"乘系数法",提出计算人体重心的实时线性计算方法。为验证该方法获得重心的准确性,实验利用平板压力测试系统Footscan提供的同步重心数据作为标准重心数据对该方法进行检验,结果表明本方法的重心计算结果与Footscan有类似的结果,在大幅度动作中有更好的准确性和稳定性。
[Abstract]:The center of gravity of human body is the basic parameter that reflects the characteristics of the human body's shape structure and mass distribution. This paper discusses how to obtain the more accurate position of the center of gravity by using the somatosensory interactive device. Firstly, the coordinate data of the human body are acquired by means of the somatosensory interactive device (Kinect), and the link model of the center of gravity of the human body suitable for the human body center of gravity calculation of the Kinect is constructed. In this paper, a real-time linear method for calculating the center of gravity of human body is proposed, which is based on the improved algorithm of "multiplicative coefficient", which is an improved method of moment synthesis in the calculation method of human gravity center. In order to verify the accuracy of the method, the synchronous barycenter data provided by the plate pressure test system Footscan is used as the standard barycenter data. The results show that the barycenter calculation results of this method are similar to those of Footscan. Better accuracy and stability in large-scale movements.
