| 摘 要： | 针对目前三维仿真城市地图展示中单一视角因视线遮挡造成信息丢失的问题,提出了一种多视角三维仿真地图方法,即通过多个可以互相切换的视角对三维仿真城市地图数据进行发布与展示,多视角三维仿真地图具有信息量大、色彩鲜明、形象立体的优点。该文在分析多视角三维仿真地图数据的基础上,给出了数据组织模型,提出了三维仿真地图的多视角逻辑坐标与地理坐标的转换方法,实现了多视角三维仿真城市地图的可视化。

| Abstract: | Now the three-dimensional simulation city map provide only a fixed view angle to display geo data,which cause the problem of geo data loss inevitably because of map blind point.To a certain extent,this problem limits the expression of geo information.In order to solve the problem,a method named multi-angle three-dimensional simulation city map is put forward in this paper,which display three-dimensional map by many switchable view angles to reduce the geo data lose.This method is divided into three parts to... |
