摘要
城市道路交通网络的日益复杂,使得现有的二维电子地图无法直观的反映道路之间的交错关系,基于二维电子地图的车辆导航系统在复杂的道路交叉口的路径引导也显得无能为力。提出建立复杂道路口的三维虚拟场景和实现场景的指定路径漫游,并以立交桥为例在VC++6.0中实现二维电子地图与三维虚拟场景的互响应,充分结合二维电子地图在车辆导航过程中的整体性、宏观性与局部三维虚拟场景的直观易懂性等优点,提高现有的车辆导航系统的路径引导效率。
The road traffic network of urban is more and more complex, the existing two- dimensional electronic map isn＇t able to reflect the staggered relations of the roads direct - viewing and the vehicle navigation system based on the two - dimensional electronic map appears helplessly facing the route guiding of the complex crossings. This article tries to establish a three dimensional virtual scene of the complex crossings and realize the scene roaming of the assigned route, and then realize the dynamic response between the two - dimensional electronic map and the three dimensional virtual scene in VC ＋ ＋ 6.0 in case of overpass. It will fully combind the entirety, macrograph of two - di- mensional electronic map and the direct - viewing, understandability of the local three dimensional virtual scene for enhancing the guidance efficiency of the existing vehicle navigation system.
