3D coverage path planning for UAVs is a crucial
problem in diverse practical applications. However, existing
methods have shown unsatisfactory system simplicity, computation efficiency, and path quality in large and complex
scenes. To address these challenges, we propose FC-Planner,
a skeleton-guided planning framework that can achieve fast
aerial coverage of complex 3D scenes without pre-processing.
We decompose the scene into several simple subspaces by a
skeleton-based space decomposition (SSD). Additionally, the
skeleton guides us to effortlessly determine free space. We
utilize the skeleton to efficiently generate a minimal set of
specialized and informative viewpoints for complete coverage. Based on SSD, a hierarchical planner effectively divides
the large planning problem into independent sub-problems,
enabling parallel planning for each subspace. The carefully
designed global and local planning strategies are then incorporated to guarantee both high quality and efficiency in
path generation. We conduct extensive benchmark and realworld tests, where FC-Planner computes over 10 times faster
compared to state-of-the-art methods with shorter path and
more complete coverage. The source code will be open at
https://github.com/HKUST-Aerial-Robotics/FC-Planner.
