摘　　要：针对目前大多数航迹规划研究中航迹规划结果直观性较差的问题,以直升机为对象,在对数字地图预处理的基础上规划其最优三维航迹.以建模工具Creator和开发工具Vega为平台,完成对地形地貌场景的三维建模及整个视景仿真系统的构建,并在此基础上利用Vega API和VC++实现满足实时性要求的规划航迹三维可视化仿真演示.该系统为航迹规划和完整的视景演示提供有效方法和步骤.With the issue that the intuitiveness of results is not good in the majority of present research on trajectory planning, the optimal 3D trajectory is planned for helicopter based on the pretreatment of digital map. The models of terrain and feature of scene and a whole visualization simulation system are completed by modeling tool Creator and development tool Vega. The demonstration which meets the real-time requirement is implemented for planning 3D trajectory＇s visualization simulation by Vega API and Microsoft VC＋＋. The system provides useful means and step for trajectory planning and demonstration of whole visualization simulation.
