TODO4-关于无人车lattice
目前看来,无论是控制空间还是状态空间采样,都有两种,一种可以用于全局,一种只是局部:
- 基于A*的的全局lattice planner
- 单层lattice的local planner
论文1:
这个论文,是基于A*的lattice planner
High Performance State Lattice Planning Using Heuristic Look-Up Tables
论文2:
这个论文,是单层lattice,local planner
1.构建单层lattice搜索空间
State Space Sampling of Feasible Motions for High Performance Mobile Robot Navigation in Highly Constrained Environments
State Space Sampling of Feasible Motions for High-Performance Mobile Robot Navigation in Complex Environments
2.轨迹生成(BVP)
Optimal Rough Terrain Trajectory Generation for Wheeled Mobile Robots
3.路径跟踪
