摘　　要：随着虚拟现实技术的发展和成熟,这项技术渗透到了越来越多的领域,特别是在康复医学领域发挥了巨大的作用。本文主要介绍了一个基于OptiTrack运动捕捉系统搭建的虚拟训练平台。它捕捉并记录分别贴在肩部、肘部和腕部的三个反光标记点的坐标值,从而建立一个虚拟的手臂模型,并通过现实的手臂动作实时驱动。整个程序是由VC++和OpenGL共同实现的。该系统以正常人和脑卒中患者为实验对象进行测试,完成了喝水这一动作。实验结果验证了该平台的有效性,它未来在上肢康复领域具有潜在的应用前景。With the development of the virtual reality technology, it has been applied into more and more fields, especially in rehabilitation training. This paper introduces a virtual training platform which is based on the virtual reality technology. Three retro-reflective markers were attached to shoulder, elbow and wrist, respectively, and the coordinates of the markers are recorded by the motion capture system. A three-dimensional model of ann was built, and the virtual model was driven by the ~tual movement of the ann in real time. The programs were realized by the Microsoft Visual C＋＋ and OpenGL. The platform was tested on a healthy person and a patient after stroke, and the movement of drinking was designed. The results illustrated the efficiency of the platform, and the platform is promising in the rehabilitation of upper limb in the future.
