【摘要】 随着互联网信息时代的来临，由于二维码技术具有信息容量大、容错能力强、成本低等特点使得二维码技术被广泛应用在各种场景，并成为现代生活不可或缺的一部分。通过识别物品上的二维码来了解相应物品的来源以及详细信息的同时也带来了另外一个问题，粘贴在柱面物体上的二维码由于图像畸变或者扭曲造成使用的二维码识别程序不能实现准确的辨识。论文通过对曲面二维码进行图像处理、二维码区域定位和提取以及扭曲校正处理来将扭曲的二维码转换到传统的平面上，从而提高柱面二维码的识别率。更多还原

【Abstract】 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 corresponding 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.更多还原
