摘要
首先介绍了基于投影的地图匹配算法的定位原理;其次,指出了直接投影算法存在的不足;最后,对直接投影算法进行了改进,设计并实现了一种基于类投影的地图匹配算法.从实验结果来看,该算法基本上实现了在1∶10000的GIS(电子地图)环境下的车辆定位功能.
This paper introduces the positioning principle of mapmatching algorithm based on projection, then points out the defects of this direct projection algorithm, and then modifiesthe former algorithm and puts forward a new algorithm based on analogous projection. From the results of the experiments, this algorithm is able to performed the vehicle positioning function under the guidance of GIS (1:10000) on the whole.
