摘要: 介绍了地图匹配的基本概念。为构建导航型数字地图数据库,基于弧线、节点和索引文件建立了数字地图面向弧线的数据库结构。在分析了基于面向弧线数据结构的地图匹配方法基础上,结合距离、方向和连通性要素给出了地图匹配可信度的定义,并对地图匹配的流程进行了分析和仿真。

Abstract: The basic concept of Map-matching is introduces in this paper. To get navigable digital map database, the arc-oriented database structure based arc-, node- and index- file is created. Together with distance, direction and connectivity factors, the confidence level of map-matching is defined on the basis of analysis of map-matching method for the arc-oriented database. The analysis of map-matching block diagram and simulation are given in the final.
