摘　　要：在二维条码图象扫描输入过程中 ,扫描图象会出现一定的倾斜 ,给条码的识别带来困难。本文提出基于 HOUGH变换的图象矫正方法 ,结合条码自身的特征 ,通过一定的预处理 ,实现二维条码图象的快速矫正 。During the process of 2D\|barcode image scanning, sometimes the input image may slant, which causes the difficulty to recognize the 2D\|barcode correctly. The method of image slant correction based on Hough transform provided in this paper realizes how to correct promptly through connecting with the particular characteristic of barcode and preprocessing, which has been proved to be practical.

关 键 词：条码识别 图像矫正 HOUGH变换 扫描图象 行差运算
