摘要
分析了GPS误差来源,并提出了相应的处理办法;融合电子地图中的道路数据和GPS所提供的定位数据的地图匹配算法,可以有效地提高车辆导航的定位精度。在分析各种地图匹配算法基础上,提出了一种实用的地图匹配方法,并且在实践中得到了验证。
This paper analyzes the given source of GPS errors and puts forward processing methods. The map matching algorism, the fusion of the road data in digital map and the positioning data given by GPS can effectively improve the positioning accuracy in navigating system for vehicle. On the basis of the analysis to some map matching algorisms, a utility map matching method is proposed in the paper, and is tested in practice.
