Implementation of Cylindrical QR Code Distortion Correction
With the advent of the Internet information age,QR code technology has been widely used in various scenarios and has become an indispensable part of modern life due to its characteristics of large information capacity,strong fault tolerance and low cost.While identifying the two-dimensional code on the item to understand the source and detailed information of the corre-sponding item,it also brings another problem.The two-dimensional code pasted on the cylindrical object can not achieve accurate identification due to image distortion or distortion.In this paper,the curved two-dimensional code is converted to the traditional plane by image processing,two-dimensional code region positioning and extraction,and distortion correction,so as to improve the recognition rate of cylindrical two-dimensional code.
