矩阵式二维码的译码系统设计与实现

Design and implementation of decoding system for matrix two-dimensional code

二维码具有高密度、高容量、高强度、安全性好、强纠错能力等优点,被广泛应用在不同领域。条码的设备和服务必然会拥有巨大的需求市场,对二维条码译码技术的研究意义重大。随着条码技术的不断提高加之二维条码的应用空间越来越广,国内外对二维条码的研究、应用也越来越多。本文介绍了二维条码的结构和特点,对快速响应矩阵码(QR码)的译码系统进行研究,重点研究其译码过程中的RS纠错算法,最后利用C++语言在Visual C++6.0平台上实现译码并测试,效果比较理想。

The two-dimensional code is widely applied in different fields because of its diverse advantages： high-density, high-capacity, high-strength safety, and strong error correction capability. The equipment and service of the bar code will have huge market demand, therefore, the research of decoding technology of two- dimensional code has great significance.With the wide range of two-dimensional code applications, there are more and more and researches and applications.The structure and characteristics of two-dimensional code are introduced, the Quick Response code （QR code） decoding system is researched, focusing on the decoding process of RS error correction algorithms, finally C＋＋ to decode is used to test the function in Visual C＋＋6.0 platform, and the results are satisfied.
