基于多维摄像系统的人体上肢动态测量

Human upper limb dynamic motion measurement based on multi-dimensional video system

由三架或三架以上普通摄像机、运动学分析软件APAS以及标定框架等构成多维摄像系统。在建立上肢运动模型的基础上,对附着体表的人工标记点的运动进行跟踪测量,利用运动学分析软件APAS分析得到标记点的空间运动坐标,通过设计优化算法程序获得人体上肢的空间运动参数。

Using a multi-dimension video system based on general camcorder, to measure human motion. The system is formed by three or more camcorder, kinetic analysis software APAS and calibration frame. The main principle of measurement is that based on the kinematics model that has been built, the marker＇s motion data that obtained by 3D reconstruction from APAS is used to get the parameter information of spatial movement of human upper limb in daily life. A optimize algorithm is presented to calculate the dynamic data of joint angle, offered detailed knowledge of the types and moments at the joints to design the bionic replacements of human upper limb.
