【摘要】：针对现有地图匹配算法的优缺点,该文结合车辆导航特点对空间道路数据进行网格化处理并建立拓扑关系,改进了交叉路口的地图匹配算法,充分利用航向信息设计了基于航向垂线地图匹配算法。通过实际动态测量获取的数据,验证了该算法在解决交叉路口误匹配、不匹配和匹配精度低等问题中的优势。在提高匹配精度和准确性的同时,该算法的解算速度同样能较好地满足导航实时性的要求。
[Abstract]:In view of the advantages and disadvantages of the existing map matching algorithms, this paper combines the characteristics of vehicle navigation to mesh the spatial road data and establish the topological relationship, and improves the map matching algorithm of intersection. A map matching algorithm based on course vertical line is designed by making full use of course information. The advantages of the algorithm in solving the problems of mismatch, mismatch and low matching accuracy are verified by the actual data obtained by dynamic measurement. While improving the accuracy and accuracy of the algorithm, the speed of the algorithm can also meet the requirements of real-time navigation.
