| Abstract: | The principle of rendering the 3D realistic terrain scene using the remote sensing images and the algorithm of texture mapping is introduced. The main procedure includes: measuring the coordinates of the characteristic points (targets) in the remote sensing images;determining the relation between remote sensing image and corresponding terrain model;grey resampling;displaying the realistic terrain scene. The results of the test show that the 3D realistic terrain scene rendered contains substantial information and has a good quality and reality. |
