| Abstract: | Based on the research of Gauss-Kruger projection and Mercator projection,we design and implement an algorithm of image collecting,then we solve the distortion problem of bmp projection in the course of building global,the algorithm greatly improves the rending effect and displaying postion veracity of the pyramid texture in global 3D visualization system,the production mostly applies to the storage of global massive texture data. |
