摘要
如何进行合理的拆卸路径规划是虚拟维修技术必须解决的难题之一。在对虚拟维修中拆卸路径规划基本流程分析的基础上,得出虚拟维修拆卸路径规划的关键技术,并提出了基于vgPicker类的拾取方法、基于鼠标运动与虚拟实体运动关联的拖曳方法和一种快速而精确的碰撞检测方法。相关算法在某型装备虚拟维修训练系统VMTS中得到应用,并对其他复杂装备的拆卸维修训练有指导意义。
Disassembly path planning is one of the key technologies of virtual maintenance. Based on the analysis of basic workflow in disassembly path planning, the key technologies of disassembly path planning in virtual mainte- nance were pointed out. The method based on the vgPicker class was established to pick up virtual object in the virtu- al environment. The method of dragging virtual object in the virtual environment was established. A collision detec- tion algorithm was proposed. Relation algorithms have been verified in the self-developed system named Virtual Ma- intenance Training System, which also can provide effective direction of disassembly maintenance training of other complex equipment.
