车辆导航与监控中GPS/GIS实时定位配准误差分析
中国科学院遥感应用研究所,北京100101
摘要:

该文对车辆导航与监控应用中GPS定位测量结果与数字地图的实时配准误差进行了深入分析,并结合实践推算了各环节误差量,在此基础上提出了消除或减轻误差的方法,使得在现有基本硬件配置条件下,车辆导航与监控应用中GPS定位测量结果与数字地图的配准误差减至最小水平。

Matching Error Analysis of GPSPositioning and Digital Maps in Vehicle Guidance and Monitoring
Abstract:

The matching errorof GPSpositioning results and GISdigital mapsin vehicle guidance and monitoring appli cationsare analyzedinthispaper.Accordingtothe errorsources andthe procedure ofdata processing, the matchingerror is divided intofive parts.Itisdetailedinthis paperthe possible errorextents ofthe coarseerror, conventionalerror, and theincorrectcoordinatetransformation and projection methods.The errorprocessing methods are discussed concerningthe stepsrespectively.Furthermore, a map matching methodis putforwardtoimprovethe matching results, andthe effectis discussed.The presented methods minimize the matching error of GPSpositioning and GISdigital mapsin vehicle guid ance and monitoring with the basic hardware platforms available.
