| Abstract: | AutoCAD is a kind of common software for map vector, but the image rectification function of Auto CAD is very limited. If the distorting errors on the map image are uniform, AutoCAD has no methodsto rectify map image. It proposesa method of image rectification on the pixel level, which im-proves the accuracy of image rectification and suits the map image of uniform errors. This methods has been finished with C++ language and ISMAPI. |

| Keywords: | ISM (imaging support module) scanning map image pixel coordinate grid image rectifi-cation |
