摘　　要：针对传统QR(quick response)条码技术的缺陷及其应用瓶颈,提出一种彩色QR条码技术方案.通过扩大码字符号的尺寸,减少其数量降低算法的空间复杂度;仅采取一种编码模式,利用位长的标示符来控制数据编码,达到码字流压缩的目的;选择6种对比度最大的颜色映射码字流,以便译码时降低识别难度.仿真结果表明,文中设计的彩色QR条码相比传统QR条码技术方案,信息密度更高,条码容量更大,视觉表现力也更强,该技术方案有效可行.Aiming at the technical disadvantage and the applied bottle-neck of the traditional QR barcode, a technical scheme of colored QR bareode was put forward. The space comp/exity of algorithm was reduced by expanding code-word symbol size and reducing the symbol quantity. Besides, only one encoding modem was taken, which controls encoding by bit length identifier, to achieve the purpose of code-word stream compressed. In order to reduce the difficulty of decoding identification, selecting six kinds of color of maximal contrast were mapped into the code-word stream. Simulation results show the colored QR barcode technology has higher information density, larger capacity, and stronger visual expression than that of the traditional QR barcode technology. This technical scheme is effective and feasible.
