Research on rectifying distortion in digitization with digital camera based on grids
Bo Liu · Computer Engineering and Applications Journal · 2007
In this paper,an approach is presented to rectify the distortion of digital cameras by the affine transform.We use several technical of image processing to rectify image,including template matching,affine transform,re-sampling and image merging.The experiment show that this algorithm divides the image into a lot of unit grids,rectifies grid one by one,guarantees the rectificative precision,improves the rectificative efficiency.
