FUEL

FUEL is a hierarchical framework for Fast UAV ExpLoration. It contains a Frontier Information Structure (FIS), which can be incrementally updated with the online built map and facilitate exploration planning in high frequency. Based on FIS, a hierarchical planner plans optimal global coverage paths, refine local viewpoints, and generates minimum-time local trajectories successively.
Our method is demonstrated to complete challenging exploration tasks 3-8 times faster than state-of-the-art approaches.
