摘要
介绍自行设计的一种依历史轨迹推导的算法 ,在此基础上针对地图匹配过程中出现的问题 ,提出一种地图匹配的智能型综合算法 实验证明 :该算法是一种精度高、效率好。
Map matching can improve the positioning precision in Vehicle Navigation Positioning System Present algorithms take into account only a certain influencing factor A new algorithm relying on history tracking is presented It traces all possible sources of errors and makes corrections accordingly throughout the whole process of data processing, including checking the validity of GPS readings, verifying whether the previous matching is a branching point, is it located within the tolerance of shortest range or still following the previous road etc Experiments show that the synthesized approach is effective and reliable
