基于GPS的地图匹配算法研究

摘要

介绍了GPS的定位原理及GPS定位数据到平面坐标的转换。从理论和工程的角度实现了GPS数据与数字地图的匹配，并使用两种方法实时显示车辆行驶轨迹。最后以太原小店区两幅区域地图为例，验证匹配算法。%This paper introduces the principle of GPS positioning and the conversion of GPS location data to plane coordinates, realizes the matching of GPS data and digital maps from theoretical and engineering views, and use two methods to display the vehicle trajectory. Finally, it takes the Taiyuan Xiaodian District map as an example to verify the matching algorithm.
