摘要
研制出基于彩色地图的地形三维数据快速采集系统。它通过对彩色地图图像进行分色、定向、跟踪等处理 ,自动、快速获取高精度的地形三维数据 ,以便建立地图数据库、地形三维模型和对地理信息系统进行相应数据的更新。
The rapidly collecting system of three-dimensional terrain data based on color map is described,which can get high precise three-dimensional terrain data automatically and rapidly by color separation?direction and track,so that we can establish map database and three-dimensional mode and update GIS data.
