AI Technical Summary
Technical Problem
Existing map data matching methods use intersections as the matching granularity, resulting in low automation and poor accuracy, and making it difficult to effectively accommodate differences between maps of varying precision.
Method used
A matching method using road segments as anchor points is adopted. By determining the relationship between road segments in high-precision maps and road segments in low-precision maps, path matching is determined, thereby achieving refined matching of map data.
Benefits of technology
It improves the automation rate and accuracy of map data matching, reduces the impact of differences between maps of different precision on the matching process, and reduces the possibility of matching failure.
