| 摘 要： | 单一的GPS车载定位会因为地理环境等原因在一定范围和时间内失效或定位不连续,针对这一局限性,提出了一种采用GPS/DR与电子地图匹配的定位算法;该算法是把车辆轨迹与数字地图模块提供的路径相比较,通过匹配过程来确定车辆关于地图的最大可能位置;该算法不仅克服了GPS信号在盲区间断或失效的缺点,也避免了DR定位误差随时间的不断积累,提高了定位精度和系统的可靠性。

| Abstract: | Only one GPS vehicles localization system may be out of work for some geographical environment' s factors,so a localization -algorithm of GPS/DR/MAP Matching integrated system is proposed.This algorithm compares the path of the vehicles with the way of the digital map.By this matching process,it determines the most possible position in the map.The algorithm not only overcomed the shortcom- ing which GPS signal can not be work in the blind spot,but also avoided the DR localization-error that accumulates with time,enhanced the precision and reliability. |
