AI Technical Summary
Existing point set maps cannot simultaneously consider the orientation requirements of moving objects reaching the target point in path planning, and path planning efficiency is low and resource consumption is high in large-scale scenarios.
A road network topology-based path planning method is adopted. A directed graph structure is generated through map parsing. Combined with lane information and vehicle orientation values, path search and determination are performed to ensure that the moving body meets the orientation requirements at the target point and improve path planning efficiency.
It achieves the goal of ensuring the moving body meets the orientation requirements at the target point while reducing memory usage, improving path planning efficiency, and adapting to the path planning needs of different vehicle models.
