基于GPS信号的导航地图路网生成方法研究

Research on Creation of Navigation Road-net Map Based on GPS Signals

基于对制作电子地图传统方法特点的分析 ,结合车辆导航用电子地图中道路网络的需要 ,提出一种利于GPS卫星所提供的平面二维位置信息来生成道路网络的新方法。文中介绍该方法的基本思路、实现方法、优缺点以及改进的方法。实际应用表明 ,该方法可以应用在制作电子地图道路网络中。

Based on the analysis of the characteristics and defects of the traditional method to create electronic maps(E-maps) and the requirement of road net in E-maps used for vehicle navigation,this paper present a new method to create road net through the planar information provided by the GPS signals.The idea,implementation,advantages,disadvantages as well as improvement of the method are also discussed in this paper especially the road net relationship between the new roads and old ones,and the attributes of newly generated road nodes using GPS signals. The author′s practical application indicates that this method could be used in generating of E-maps based on GPS signals.
