AI Technical Summary
Existing single high-precision maps have insufficient data coverage, with some roads not covered, making it impossible to start the autonomous driving system. Furthermore, there is no redundant backup, resulting in high system risk.
The method based on dual high-precision maps is adopted to periodically collect the vehicle's current coordinates and environmental information, obtain the first and second high-precision map data, perform differential fusion, plan autonomous driving strategies, and perform element fusion when the difference value is less than a threshold to correct the vehicle's positioning coordinates.
It improves the coverage and robustness of high-precision maps for autonomous driving systems, reduces risks caused by problems with high-precision maps, and ensures the reliability and safety of autonomous driving systems.
