摘要
人体真实感建模是虚拟人研究领域的一项重要内容。该文提出一种基于模型的快速人体建模方法。人体几何模型的皮肤层由多边形网格组成的表面表示,骨架层建模采用H-Anim标准,并针对Poser软件输出的人体模型缺乏关节点数据问题,给出一种骨架提取算法。人体运动模型应用机器人运动学方法,由骨架层驱动皮肤层实现。在VC++平台上实现对不同姿势下人体模型的骨架提取,仿真了敬礼过程中手臂的运动,验证了该方法的可行性。
Realistic human modeling is one major part in the field of virtual human research. In this paper, a method of model-based human body fast modeling is presented. The skin layer of human geometric model is constructed by Polygon mesh surfaces and the skeleton layer according with H-Anita standard. Aiming at lack of joints center position data in model files exported by Poser software, an approach of extracting human body skeleton is given. With the skin layer deformation driven by the movement of skeleton, human body dynamic model is built by using the kinematics theory of robotics. Skeleton extraction results with various postures and simulation of arm motion for salute action are achieved on the platform of VC＋＋, which show the method presented is effective.
