项目摘要

In this study, the three-dimensional motion capturing system was developed using digital video cameras. This system enables the measurement of the movement and behavior in the subject wearing regular clothing such as working uniform under all measuring circumstances. Using this system, the knee flexion and extension were measured under two wearing clothes conditions : an actor suit and a working uniform. The reconstructed motion results have good agreement with those with X-ray medical judgments. And the load bearing function was analyzed the low-flexion posture under a static load condition using a non-linear finite element analyses of the knee joint. When the medial collateral ligament was removed the knee joint ceased the function as load bearing at applied loads. And the minimum principal stress value of the other ligaments increased compared with that in the normal knee joint.

在本研究中，使用数码摄像机开发了三维运动捕捉系统。该系统能够在所有测量情况下测量穿着常规服装(如工作服)的对象的运动和行为。利用该系统测量了演员套装和工作服两种穿衣条件下膝关节的屈伸运动。重建的运动结果与X光医学判断有很好的一致性。并对膝关节进行了非线性有限元分析，分析了静载条件下低屈姿势的承载作用。去除内侧副韧带后，膝关节在外力作用下不再具有承重功能。其他韧带的最小主应力值均较正常膝关节增大。
