基于路径表的室内地图匹配方法
Indoor map matching method based on link table
摘要
Abstract
Map matching algorithm is an indispensable step of positioning technology. It can obviously improve the posi-tioning accuracy. In order to improve the accuracy of map matching and apply to indoor positioning situation, an indoor map matching method based on link table is proposed. This method establishes a link table to deposit the information of candidate links based on traditional map matching, and selects the most likely correct link from the link table when it needs. Due to the mechanism of error checking and recovering, this method can reselect the correct link from link table when the mismatching happens. The function of these mechanism makes this method especially suitable for the complex indoor environments. Experimental results show that, compared with traditional map matching approaches, this method can obviously improve the map matching accuracy.关键词
