二维条码码图结构特性分析
The symbol structure properties of the 2D bar code
【摘要】 介绍了QR二维条码和PDF417二维条码的码图结构.将构成码图的模块分为模式特征区域和数据符号区域.并对这两个区域的特性进行了分析,比较了在模块数量相近的情况下,这两种条码的信息容量.最后,对二维条码码图结构的设计提出了几点建议.
【Abstract】 The symbol properties of the PDF417 2D bar code and the QR Code 2D bar code are introduced. The symbol blocks are sorted to two classes(pattern area and code area). The properties of the two areas are analysed. The message capacity of the two kinds of bar code are compared under the condition that the blocks are equal. Finally, some suggestions about the 2D bar code symbole structure design are proposed.
