摘　　要：为了进行人体完整腰椎的运动学研究，设计和制造平行光三维运动测量和分析系统。改进加载装置，以减少实验设备对腰椎运动的干扰。随着载荷的改变，人体新鲜腰椎标本产生不同的运动。通过测量系统，设立在每个椎体上的三个标志点的运动分别投影到光屏，摄像机动态记录，输入计算机图像处理系统。利用刚体运动的原理进行计算，获得各标志点的三维运动量的完整腰椎的运动学特点。The parellel light measurement and analysis system was designed and manufactured for research on kinematics of the whole lumbar spine.A loading frame was improved to decrease interference of experiment equipment for movement of lumbar spine.Along with load was changed,fresh human ligamentous specimens of lumbar spine were presented the different motion;The movement of three marks,which fixed in vertebrae,were separately projected to light screen of the system,kinematically recorded with video camera,inputted to image processing system.Then,according to prineiple of rigidity movement we proceeded with calculation,and obtained three-dimensional motion measurement of marks and kinematic characteristic of the whole lumbar spine.
