| 摘 要： | 在对三维电子地图建模的基础上,提出了一种基于单GPS的虚拟差分、高程辅助定位和碰撞检测误差消除相结合的车道级车辆定位方法.该方法将车辆定位分为两次地图匹配过程,即首次通过虚拟差分技术和高程辅助定位技术对GPS定位参数进行修正,提高定位精度,然后在三维电子地图中结合碰撞检测技术实现车道级匹配.通过实地DGPS跑车对比实验,证明该方法完全能够满足车道级路径引导的要求.

| Abstract: | On the basis of modeling of 3D digital map, a lane-level positioning method was presented based on virtual differential GPS with single GPS receiver, height aiding, and collision detecting technique. The method divided vehicle positioning into two map matching process. Namely, for the first time, GPS positioning parameters were revised through virtual differential technology and height positioning aiding technology in order to improve the precision. Then, lane-level matching was implemented in 3D digital map based on the collision detection technology. Tested by DGPS data, the method was proved to fulfill the demands of vehicle navigation system. |
