摘　　要：依据人体的关节连接体层次结构,将各肢体抽象为简单的刚性几何实体,构建了人体骨骼模型,通过定义人体坐标和肢体局部坐标及其相互间的变换,描述了人体骨骼模型中各关节之间的相对位置和姿态的变化。详细论述了应用D-H方法分析人体上肢运动模型的方法,最后利用VC++构建了基于OpenGL技术的虚拟人体运动程序。该应用程序可以在虚拟环境中载入、驱动并显示一个三维虚拟人。它能够灵活的利用采集得到人体运动数据驱动虚拟人,可以应用于医学仿真、智能人机交互等领域。In this paper, based on the body＇s joints connecting of hierarchical structure, the body is described as a simple rigid geometric entity, and a human skeleton model is established, By defining Human coordinates, local coordinate limbs, and their mutual transformation, the relative position and posture change between joints in a human skeleton model are described. The analysis of the upper body motion model is discussed in detail using D - H meth- od. Finally virtual human movement simulation system is set based on the OpenGL in VC ＋ ＋. The application program can drive and display a 3D virtual people in the virtual environment. It can drive a virtual human using collected human motion data , and can be used in medical simulation, intelligent human - computer interaction, and other fields.
