摘要:
目前GPS技术被广泛应用在各个定位和导航中,但是由于GPS系统存在一定的误差,需要通过地图匹配算法将GPS定位数据结合电子地图进行纠正匹配,以提高GPS定位精度。文中通过缓冲区分析获取待匹配道路集合,利用路网拓扑结构,筛选出其中拓扑不相关的匹配道路,同时根据最小距离原则,从多条待匹配道路中找到正确道路。除此之外,文中针对其中由于信号缺失或者定位误差所造成的不连续位置,将其分解成多条连续集合,使道路匹配更加合理。对实际GPS轨迹数据处理结果表明,该方法在复杂路网中有较好的匹配效果、效率较高,具有实用价值
Abstract:
GPS technology is now widely used in GPS systems. But because there are some positioning errors, it's necessary to relocate the GPS data by using map-matching algorithm to improve GPS positioning accuracy. In this paper, first of all, obtain the matched set of roads by buffer analysis, then filter out the useless road set by the use of network topology. While according to the principle of minimum distance, find the correct path. In addition, because of the existence of the missing or non-consecutive locations, it can divide into a number of continuous road sets to improve the accuracy of map-matching result. The effectiveness and applicability of this map matc- hing algorithm is demonstrated by real road experiments
