摘　　要：在大范围城市交通态势显示和交通仿真中,使用卫星地图为背景可提供更强的真实感和可信度。目前商用类似技术中,常用的GPS路网叠加卫星地图的方法,存在GPS路网和卫星地图不能准确匹配对齐的问题。文中提出一种新的路网合成方法,通过融合处理GPS路网信息和卫星地图信息,使用图形图像处理方法,从而得到准确对齐的城市路网。该方法包括GPS路网信息,及卫星地图处理和路网合成处理两部分,并且通过实验证明了该方法的有效性和实用性。In the large scale of urban traffic situation display and traffic simulation, it will provide more realism and credibility to use the satellite map as the background of the display and simulation. Currently, in the most of similar commercially technology, there are the problem that road network and GPS satellite maps can not be accurately aligned in the commonly used method. In this paper, propose a new method for the synthesis of the road network,through the integration of GPS road network and satellite map, and using the graphics and image processing algorithms, it can be get the accurate alignment of urban road network. The method includes two parts, the first part is GPS road network information, the second is satellite map processing and synthesis of road network processing. The experimental results demonstrate the effectiveness and practicality of the method.
