摘要 在深入分析手的解剖结构和运动特点的基础上 ,采用层次结构建模方法 ,建立了虚拟手模型 .然后针对已有的虚拟手抓取规则过于简化的特点 ,提出了一种新的虚拟手抓取规则 .该规则能够使虚拟手正确地抓取虚拟环境中的物体 .最后运用虚拟手模型和抓取规则实现了虚拟手对虚拟物体的抓取。 In this paper, we have established a virtual hand model with a hierarchical structure based on the analysis of hand anatomical structure and joint motions. Then a new rule for grasping is proposed and basic virtual hand operations such as grasping, moving, and releasing are implemented. This grasping rule makes the user be able to correctly grasp the complex virtual objects.
