摘要
在利用图像方式识别条码过程中,由于摄像头和QR码之间的位置关系的不同,会导致捕获生成的QR码图像产生倾斜、畸变等问题,提出了通过空间变换和双线性变换的方法矫正变形的条码图像。实验证明,方法简单有效,可以提高QR条码的正确识别率。
In view of the positional relationship between the camera and QR code,it will lead to the captured image including distortion and tilt.This paper presents the space transform and bilinear transformation method for the correction of deformation of QR code image.Experiments can prove that this method is simple and effective,and this method can improve QR code recognition correct rate.
