In order to improve the visual degree of assembly path planning & simulation, an assembly path planning method based on viewpoint tracking was proposed. The principles of the method were analyzed, in this method, the relative position between viewpoints and moving assembly unit was adjusted by model view matrix, the motion of assembly unit was controlled by the transform of pose matrix, and the assembly path was managed by the views. A multi-level dynamic path collision detection algorithm based on projection was adopted to verify the validity of the path. An assembly process planning & simulation system was developed, and the method was verified by a complicated airplane component, the results show that the method can improve the visualization of the assembly path planning & simulation. 

为了改善装配路径规划与仿真的真实化程度,提出了一种基于视点跟随的装配路径规划方法。分析了基于视点跟随的装配路径规划原理,该方法通过视点变换矩阵来调整视点相对于运动装配单元的位置,通过位姿矩阵来控制装配单元的运动,通过视图来对装配路径进行管理。采用一种基于投影法的多层次动态路径干涉检查算法来对装配路径的有效性进行验证。开发了一个装配工艺规划与仿真系统,并以某型号飞机右机翼为例对方法进行了验证,结果表明,该方法能够改善装配路径规划与仿真的可视化程度。
