中文摘要: 协同虚拟现实技术具有广泛的应用背景,文中以全方位轮椅为应用对象,探讨虚拟现实技术的应用.结合Mecanum轮、连续切换轮、锥滚轮这三种全向轮的运动原理与排布方式,分析了轮椅的运动学关系.在轮椅三维Pro/E模型的基础上,利用虚拟现实建模语言(VRML)对全方位轮椅进行实时定制和仿真,通过操作定制控制台可以实现零件颜色的改变和轮椅部件的替换.运动仿真控制台可以实现轮椅的直走、横走、斜走以及原地打转等运动方式的仿真.这样用户能参与到轮椅的定制设计中,得到符合自己要求的轮椅,同时对全方位轮椅的特殊运动功能有了更加深刻和形象的认识.
中文关键词: 全方位轮椅  实时定制  运动仿真
Abstract:Collaborative Virtual Reality (VR) technology has a wide application background. An omni-directional wheelchair was used as an application object to discuss the technology of VR and so on. The kinematic relationship of the wheelchair was analyzed with combining the motion principle and arrangement of Mecanum wheel, alternate wheel, and conical wheel. The Virtual Reality Modeling Language (VRML) was used to make real-time customization and motion simulation based on the wheelchair 3D Pre/E model. The change of part color and the replacement of wheelchair components can be realized through the operation custom console. By using this method, the omni-directional movements such as longitudinal, lateral, and rotary motion can be emulated via the simulation panel. In this way, clients can participate in the design and get a wheelchair according to their individual requirements, which will give them a deeper and more impressive feeling about the wheelchair's special motion functions.
