虚拟维修是近年来提出的一个新概念,并在维修性分析、维修训练等领域得到广泛的应用。为了解决维修过程仿真中的维修人员仿真问题,提出了一个分阶段的虚拟人移动仿真方法,采用随机运动规划方法生成虚拟人躯干及头部的无碰撞路径,利用运动捕获数据和运动变形来实现对四肢运动的仿真。在运动规划中引入了姿态转移图的概念,实现了虚拟人移动过程中多种姿势之间的自然转化。采用基于运动变形的方法消除了虚拟人上肢和环境中其他物体的碰撞现象,提高了仿真真实性。Abstract: Virtual maintenance is a new concept introduced in the last few years,and has been broadly used in maintainability analysis and maintenance training.In order to solve the virtual human simulation in maintenance process simulation,a multi-stage virtual human locomotion simulation method was proposed.The free collision path of virtual human torso and head was planned by a probabilistic motion planner.And the motion of arms and legs was simulated using motion captured data and motion warping.A new concept of pose transition graph was introduced in order to implement natural pose transition in locomotion simulation.In motion optimization,a method based on motion warping was proposed to avoid the possible collision between virtual human arms and other objects in the environment. 相似文献
