基于Voronoi图的路径规划算法在复杂环境导航过程中会因环境改变和Voronoi图结构的不变性,使全局路径规划器陷入最短路径搜索"陷阱",导致导航失败.针对这一问题,提出一种改进骨架提取的Voronoi图导航骨架重构算法.对栅格地图进行预处理,生成全局初始骨架;结合激光雷达观测模型更新代价地图,通过改变代价地图的更新方式辅助骨架重构,实现机器人正确导航.对比实验结果表明,所提算法使骨架重构具有"记忆性",在保证导航实时性的同时,提升了骨架算法的导航鲁棒性.
Research on skeleton reconstruction algorithm in Voronoi graph navigation with improved skeleton extraction
The path planning algorithm based on Voronoi graph will fall into the"trap"of searching the shortest path due to the change of the environment and the invariance of Voronoi graph structure in the course of complex environment navigation,resulting in navigation failure.To solve this problem,a skeleton reconstruction algorithm with improved skeleton extraction in Voronoi graph navigation was proposed.The raster map was preprocessed to generate the global initial skeleton.Combining with the LiDAR observation model to update the cost map,the skeleton reconstruction was assisted by changing the update mode of the cost map to realize the correct navigation of the robot.The experimental results showed that the proposed algorithm could make the skeleton reconstruction"memorized",and improved the navigation robustness of the skeleton algorithm while ensuring real-time navigation.
