摘要
快速反应码QR(Quick Response Code)是一种信息隐藏量大且读取方便的二维标记码。由于摄像头和QR标记之间的位置关系会导致捕获生成的图像产生倾斜畸变,极大地影响识读准确率。在QR识别流程中增加倾斜矫正处理,采用空间投影校正算法实现抗倾斜的QR码识别,并将其应用到档案系统防伪识别应用,提高了QR码的识别率,取得很好的应用效果。
QR code is one kind of two-dimensional tag codes which can hide a large amount of information and is easy to read.Since the images generated from camera capturing usually have some skew distortion due to position relationship between the camera and the QR code,the precision ratio of recognition and reading is significantly impacted.In this paper we add slant correction processing to the QR recognition flow,use space projection rectification algorithm to implement anti-skew QR code recognition,and apply it in forgery prevention and recognition of archives system,so that the recognition rate of QR code is improved,and preferable application effect has been achieved.
