摘要
利用 ERDAS IMAGINE8.4版图像处理软件 ,对滇藏线原始数据经过校正、数字正射影像镶嵌、假彩色合成图像增强处理后 ,通过 DEM的获取、生成与遥感图像的配准 ,制作具有三维视感的地貌影像图及可视化飞行电影动画 ,提取工程地质灾害、地质构造信息 ,从工程地质角度对新建铁路滇藏线预可行性做出评价。
With ERDAS IMAGINE 8.4 software,through rectification,digital orthographical maps inlaying,artificial color composition to Dian Zang railway by generating DEM and compounding with remote sensing image,the paper generates a three dimensional geomorphologic image and visible flight film by extracting information of geological engineering disasters and geological structure.The feasibility of newly built Dian Zang railway from the viewpoint of geological engineering has been evaluated.
