摘要
研究了地图匹配技术在车辆组合导航系统中的特点,利用模糊逻辑处理近似信息的优势和路网的拓扑结构,提出了一种基于拓扑结构/模糊逻辑的匹配地图算法,通过模糊逻辑部分的搜索子算法和投影子算法计算路段的隶属度,再结合路网自身的拓扑结构来选择匹配路段及投影匹配点,详细介绍了该算法的设计和流程。实际跑车实验证明,该算法有效地提高了匹配正确率和匹配效率。
The character of map-matching in integrated navigation system is discussed firstly. Using fuzzy logic＇s advantage in dealing with uncertain information and the topological structure of road net, a map matching algorithm based on topological structure/fuzzy logic was proposed in this paper. The searching algorithm and projecting algorithm are used to calculate the degree of the road, then combining the topological structure to select the matching road. The experimental result shows that, this algorithm improves the matching correctness and efficiency.
