基于拓扑结构的地图匹配算法研究

Map-Matching Algorithm Research Based on Topology Structure

随着GPS定位技术的日益推广,GPS技术被大量应用于各种导航系统中。但由于GPS系统存在一定的定位误差,那么如何向用户提供实时、准确的车辆位置信息成了导航系统的重点和难点。通过利用软件纠偏的方法对车辆的定位数据与电子地图数据进行配准纠正,即地图匹配,来减小电子地图的道路信息和GPS定位信息间的显示误差。该方法已应用于实际的工程应用,并取得了良好的效果。

With the development of GPS,the technology of GPS is widely used in a variety of navigation system.Since GPS system has inherent position error,how to provide accurate position information of vehicle to users in real-time is one of the most important problems for vehicle navigation system.Using software to redress the error between position data to vehicle and electric map data,or called map-mtching,can diminish the error between electric map and GPS position information.This method has been applied to practical engineering applications and has achieved a good result.
