摘要 定位数据与地图数据不符是地图匹配致力解决的问题,目前还没有理想的通用匹配算法,本文针对匹配过程中传统方法对于误差处理的不足,探讨了卡尔曼滤波的相关应用问题,考虑了将动态滤波技术引入地图匹配的直接模式和间接模式,使道路形状相关与道路形状无关情况都可以得到有效地处理,对线性系统和非线性系统都适应,这种对动态系统中观测误差、系统误差进行处理的有效方法,在模拟实验中取得了较好的结果。 Map-matching is an important part of navigation system.This article discusses the utilization of dynamic filtering in the map-matching.It also describes the vehicles mechanized condition by the CA model and data processing respectively in direct pattern and indirect pattern,and gives analysis and summary to the simulating result.
