摘要
文中研究了地图匹配技术在GPS/DR组合导航系统中的作用,分析了影响地图匹配精度的因素,模拟一种基于模糊逻辑思想的地图匹配算法。该算法通过方向性、路段的接近程度和相似性三个方面进行模糊综合评判,并且结合道路网络的拓扑结构,挑选出最佳匹配路段。仿真结果验证了该算法的有效性。
The function of map matching algorithm in GPS/DR integrated navigation is studied. The factor which affects the precision of map matching is analyzed. Map matching method based on fuzzy logic is simulated. Fuzzy-integrated judge is done by using direction, road-section approach degree and comparability, and in combining the topology of road network, the best matching road section is elected. The result of computer simulation has proved the validity of this method.
