摘　　要：提出了一种基于网格的利用仿射变换纠正数码相机几何畸变的算法。主要采用模板匹配、仿射变换、重采样等技术对数码相机拍摄的文档资料进行纠正。试验表明,该算法将图幅面划分为许多单元格,逐个单元格进行纠正,保证了纠正的精度,对于大批量图幅能提高其纠正的效率。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.
