车辆导航系统中地图匹配的研究

分析影响地图匹配实时性、鲁棒性和匹配精度的因素,针对常用投影法,概率统计法、相关性算法、基于网络拓扑以及基于曲线拟合的地图匹配算法进行描述,并针对基于D-S证据推理的地图匹配算法.匹配误差比较大的转弯路段,平行路段以及立交桥路段进行分析并且给出匹配漉程.通过实验仿真表明本文算法对复杂路口有较好的适应性和较高的匹配精度.

Research on map matching in Vehicle Navigation System

After analysis of factors of the real-time,the robust and the accuracy of map matching,the common algorithms were studied,and the advantages and disadvantages of them were summed up.And according to the map matching of D-S evidence reasoning,the matching process of complex sections was proposed.The results show that the algorithm in this paper had high matching accuracy and better adaptability in complex sections.
