说明：  在现代社会商品流通中,为了提高工作效率,条码识别技术得到了广泛的应用。一维条码受到容量的限制,仅能标识商品,而不能描述商品。二维条码解决了一维条码面临的容量问题,具有信息量大、可靠性高、保密防伪等优点。文 中介绍了QR Code 二维条形码的技术,给出了基于数字图像处理的QR Code 二维条形码的识别方案。
(Circulation of commodities in modern society, in order to improve efficiency, bar code recognition technology has been widely used. One-dimensional bar code by the capacity constraints, can only identify the product, and can not describe the goods. Two-dimensional bar code to solve the one-dimensional bar code is facing capacity problems, with a large amount of information, high reliability, confidentiality, security and so on. This paper introduces two-dimensional QR Code bar code technology, based on digital image processing gives the QR Code two-dimensional bar code identification scheme.)
