摘要
本文提出了基于 SAS的自动三维航迹规划方法。该方法通过把约束条件结合到搜索算法中去 ,有效地减小了搜索空间 ,缩短了搜索时间 ,从而使三维规划能够用于实时航迹规划。在搜索过程中地形信息得到了充分利用 ,使算法生成的航迹能够自动回避地形和威胁。实验证明 ,该方法能够快速有效地完成规划任务 。
This paper proposed an approach of 3D route planning based on SAS,which expands nodes in 3 D environment.This approach efficiently prunes the search space and shortens the search time by incorporating route constrains into search algorithm,which can be used in real time route planner.During the search process,terrain information is fully used,therefore the route generated by the planner can avoid terrain and threat automatically.The experiment results demonstrated that this method can complete planning mission efficiently and get a desirable route.
