摘　　要：本文采用白光散斑法，由两个摄像机同时记录人体关节运动过程中的数字图像，通过数字相关测出各标志点的平面位移．然后用立体摄影法求解各测点在运动过程中的三维坐标，得到各标志点的三维运动．针对刚体大位移的特点，提出了被测区域的侧转和自转指标，实现对人体关节一般空间运动的定量分析，为医学手术的评价提供实验测量基础。White-light speckle method, together with stereo-photographic method, was used in this paper to measure the 3- D displacements of mark points on the surface of the human articular specimens during spacial movement. As the articulars undergo finite displacement and rotation, index of plane tilt and plane rotation were introduced to describe the general movement instead of the common rotations about the three orthogonal axes. Primary experiments had proved the viability of the presented method, which will be helpful in evaluating the medical operations.
