【摘要】 本文通过对车辆导航过程中对地图匹配功能的需求变化分析,提出了一种自适应的动态地图匹配方法。该方法能够识别初始选择道路、跟踪选择道路和跟踪道路路段三种不同状态,并动态调整地图匹配策略。同时,开发了适合不同状态需求特点的匹配算法。大量的仿真实验结果表明该方法在保证了匹配结果准确性的前提下,有效地提高了系统的实时性。更多还原

【Abstract】 A dynamic map-matching method for adaptability is presented by analyzing the change in requirement of map-matching performance in the process of vehicular navigation.The method is provided with the capability of identifying three different states(selecting a road initially,selecting a follow-up road and positioning in the known road)and determining corresponding algorithms of map-matching dynamically.In order to satisfy the needs of map-matching in different states,some algorithms are developed respectively.Simulated experiments show that the method implements more timely map-matching successfully.更多还原
