数字图像处理算法在QR码识别中的应用

摘要

介绍了基于数字图像处理的QR码识别算法.该方案综合运用了图像灰度化、滤波去噪、二值化、边缘检测、图像旋转等多种图像处理方法对条码图像进行预处理.理论分析和实验结果表明:该算法提高了识读的灵活性和可靠性,为QR码识别提供了一种新途径.%This paper mainly focused on image processing algorithm for QR code recognition.The solution synthetically uses image graying,image denoising,image binarization,edge detection,and image rotation etcto complete the preproceasing of bar codes.Theoretical analysis and experimental results show that the solution enhance the flexibility and reliability of Recognition,provide a new way for QR code recognition.
