| Abstract: | By scanning maps into computer,combining them and founding coordinate systems, the digital maps are acheived in this paper. The digital maps have 256 colors which can be used in many cases. Thispaper introduces how to combine several images precisely to form a whole image through key points matching. A fast rotation algorithm is the presented, which exceeds others in rotation speed, loseless ofimage information etc. It can be widely used in image processing. |
