一种基于国标人体测量学数据的虚拟人建模方法

A virtual human modeling method based on Chinese anthropometry data

针对目前利用国标人体测量学数据构建的虚拟人模型,只有单一的骨骼层或皮肤层,不便于同时对虚拟人进行实时运动控制和皮肤动态变形研究的问题,提出一种利用GB 10000-88的19个人体测量学特征数据、用3ds max构造出虚拟人的皮肤网格、层级建模方法构建出虚拟人的骨骼关节运动模型与四元数球面混合插值技术相结合的虚拟人建模方法。实验结果表明,该方法构建的虚拟人双层模型有利于对准确的国标人体测量学数据的虚拟人角色进行建模、皮肤逼真变形、实时运动仿真和人机工效学分析。

Since the current virtual human models constructed directly by using the Chinese anthropometry data only have a single bone or skin layer,it is not easy to control virtual human real-time motion and skin dynamic deformation simultaneously. Therefore we present a virtual human modeling method combining the 19 sets of Chinese anthropometry feature data of GB 10000-88. We construct a virtual human skin mesh by 3ds max,a virtual bone joint movement model by hierarchical modeling method,and a virtual human model by the quaternion spherical vertexs blending interpolation technology. The experimental results show that the proposed method can construct a double-layer virtual human model, which is significant for accurately performing the virtual human role modeling, skin realistic deformation, realtime motion simulation and human-computer ergonomics analysis on the Chinese anthropometry data.
