基于 随机采样技术 的 PRM法 可以有效解决 “高维空间” 和 “复杂约束” 中的路径规划问题。 1. 简介 如上图所示,PRM(Probabilistic Roadmaps)是一种基于图搜索的方法,一共分为两个步骤:学习阶段,查询阶段 它将连续空间转换成离散空间,再利用A*等搜索算法在路线图上寻找路径,以提高搜索效率。 这种方法能用相...

Low Dispersion Probabilistic Roadmaps This implementation uses LD-PRM planning. The idea behind LD-PRM is to capture the connectivity of the configuration space with fewer samples, reducing the overall running time of the algorithm. Different to a simple PRM planner, the samples generated by the ...
