该程序可以将三维图像生成DSM深度影像，生成DSM深度影像的过程就是通过逐点内插的方法生成格网化的数字表面模型DSM，然后把DSM按照高程进行灰度量化处理，最终生成与灰度图像类似的采用灰度值大小反映高程变化的DSM深度影像。-The program 3 d images can be generated DSM depth image, the generation process of DSM depth image is generated by the method of point-by-point interpolation grid handling digital surface model of the DSM, then the DSM gray quantitative processing according to the elevation, the resulting use similar to that of the gray image grey value reflect the elevation changes to the size of the DSM depth image.
