| 摘 要： | 把图像数据库的建库思想引入到大规模3D遥感影像的制作中。在此基础上，提出利用合并分割法制作大规模3D遥感影像。将经
过特殊处理的等高线数据制成小块DEM，采用两种模式将遥感影像与这些DEM进行纹理映射，从而制作成大规模3D遥感影像。这种方法提
高了大规模3D遥感影像的制作水平，进一步增强了大规模3D遥感影像的信息量与实用性。

| Abstract: | The authors have applied the thought of image data base to creating the Large-Scale Three-Dimensional
Remote Sensing Image (L3DRSI), and put forward the new method “dividing-integrating”. The specially processed large
DEM data are divided into small blocks, and texture mapping of RS image with these DEM data is performed in two ways.
Finally, the L3DRSI is created. The new method can not only improve the precision of terrain which is very important
for L3DRSI, but also enrich the information and enhance the practicability of LRSI3D. |
