摘要:

主流的自主探索方法通常对同一区域进行过度重复探索,导致复杂场景中探索时间长且探索轨迹长。为解决此问题,我们提出一种新颖的语义区域感知自主探索方法,其核心思想是利用语义区域信息来优化自主导航策略。该方法使移动机器人在前往下一区域前充分探索当前语义区域,有助于避免过度重复探索并加快探索速度。此外,与通常构建单类型地图的现有自主探索方法相比,我们的方法可构建四种类型的地图,包括点云地图、占据栅格地图、拓扑地图和语义地图。实验结果表明,与基于经典 RRT(快速探索随机树)的自主探索方法相比,该方法在保持 >98% 探索率的同时,实现了最高 50.7% 的探索时间减少和 48.1% 的探索轨迹长度减少。

英文摘要:

Mainstream autonomous exploration methods usually perform excessively-repeated explorations for the same region, leading to long exploration time and exploration trajectory in complex scenes. To handle this issue, we propose a novel semantic region aware autonomous exploration method, the core idea of which is considering the information of semantic regions to optimize the autonomous navigation strategy. Our method enables the mobile robot to fully explore the current semantic region before moving to the next region, contributing to avoid excessively-repeated explorations and accelerate the exploration speed. In addition, compared with existing au?tonomous exploration methods that usually construct the single-type map, our method allows to construct four types of maps including point cloud map, occupancy grid map, topological map, and semantic map. The experiment results demonstrate that our method achieves the highest 50.7% exploration time reduction and 48.1% exploration trajectory length reduction while maintaining >98% exploration rate when comparing with the classical RRT (Rapid-exploration Random Tree) based autonomous exploration method.
