| 摘 要： | 利用DEM高程资料实现遥感影像的三维显示可大大提高遥感监测产品的使用价值，而商用软件成本高操作繁琐普及困难。利用计算机图形学知识和Delphi编程语言，开发了一套遥感影像三维可视化软件。对在开发过程中遇到的有关DEM数据的裁剪与拼接、图像配准、地表模拟、透视变换、消隐处理、光照和阴影效果以及颜色变换等问题的解决方案和实现方法作了简要的介绍。

| Abstract: | The 3D visualization of remote sensing images was realized by means of DEM data, which greatly improved the application of remote sensing products; however, those commercial software are costly,inconvenient to use and difficult to popularize, so a program of 3D remote sensing image visualization was developed by using the Delphi programming language based on computer graphical principles. The solutions and realizing methods for problems encountered in practice are introduced, such as cutting and the join-together of DEM data, image matching, earth surface simulation, perspective counterchange, black-out processing, effects of illumination and shadow, color change, etc. |
