关于多无人机的轨迹规划，近年来这个文章很多啊：
- Efficient Multi-Agent Trajectory Planning with Feasibility Guarantee using Relative Bernstein Polynomial(飞行走廊)
- https://github.com/qwerty35/swarm_simulator
- Fast Trajectory Planning for Multiple Quadrotors using Relative Safe Flight Corridor
- Online Trajectory Planning for Multiple Quadrotors in Dynamic Environment Using RSFC ,ICRA 2021
多车路径规划：
这个用的 Spatiotemporal Hybrid-State A*，不过用了ompl库。
