基于彩色地图的DEM快速生成系统

A Research for Rapidly Generating System of DEM Based on Color Map

研制了基于彩色地图的DEM快速生成系统。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 。

The rapidly generating system of DEM based on color map is described, which can get high precise three dimensional terrain data automatically and rapidly by color sepration,direction and track, then rapidly generate DEM by using IDL of RSI corporation.
