| Abstract: | The existing map matching method using vertical projection is often difficult to correct the longitudinal error, and the matching effect in the intersection is not good. In this paper, a map matching algorithm is proposed which makes full use of the road constraints at the intersections. We collect the location data of autonomous cars using low-cost integrated navigation method with IMU and odometer,and combine with open source OpenStreetMap for map matching, which breaks the dilemma that the autonomous driving industry is highly dependent on GPS. Experimental results show that the average time of a single point is 0.11 ms, and the proposed method is suitable for urban driving environment and meets the requirement of real-time calculation, and the matching accuracy can reach 100% while the recall rate is 89%. |
