基于电磁跟踪系统的人体上肢运动测量

Application of the Electromagnetic Tracking System to the Motion Measurement of Human Upper-Limb

根据人体上肢的特点将其运动简化为7自由度的刚体运动,利用电磁跟踪系统对人体上肢的运动进行测量。建立了固连在上肢上的关节坐标系,提出了通过电磁跟踪系统各个传感器得到的数据计算关节旋转矩阵的算法,从而可以计算出上肢运动时的关节运动数据。

Based on its characteristics, the motion of upper-limb can be simplified to rigid body motion with 7 degrees of freedom. The human upper-limb motion is measured with an electromagnetic tracking system. Coordinates related with upper-limb are built and an algorithm to calculate the matrix of transition through data from the sensors of the electromagnetic system is presented, so the motional data of upper-limb can be figured out.
