摘要: 根据分段、特征提取等地图匹配关键技术探讨了地图匹配的一般原理,提出了基于D-S证据推理理论的GPS(Global Positioning System)/MM(Map Matching)组合算法,提高了GPS单点定位精度.仿真结果和跑车实验验证结果表明上述方法是行之有效的.地图匹配算法不增加系统的硬件成本,对目前广泛应用的车载GPS导航定位系统是一个有效的解决方案.Abstract: General principles of map matching are investigated according to segmentation and feature extraction, and an algorithm based on D-S evidence reasoning for GPS/MM integrated navigation system is proposed. The single point positioning accuracy of GPS is improved. Finally, a simulation example demonstrates the effectiveness of the proposed algorithm for the requirement of vehicle position and navigation. The map matching algorithm does not increase the cost of system hardware. It is a useful solution for the widely used GPS navigation and position system.
