摘要
在对GPS接收到的定位信息进行解析的基础上,研究了GPS车辆监控系统中道路匹配的原理和方法,提出了综合考虑道路拓扑关系和连通性的直接投影匹配算法;重点介绍了该算法的技术路线、实现步骤和误差处理方法,并通过实验证明了系统算法的有效性。
Based on parsing of the positioning information that GPS has received, this paper firstly studied the principles and methods of road matching in GPS vehicle monitoring system, and then designed a comprehensive consideration road connectivity topological rela-tions and the direct projection matching method which is suitable for this system. Next, it focused on the technical route, implementation steps and error handling method of the algo-rithm. Finally, the experimental results showed the effectiveness of the system algorithms.
