Abstract

With the rapid development of internet technology and intelligent equipment, the dissemination and recognition of information has become a necessary technology in modern society. As a relatively concerned and widely applicable means of information dissemination, although the two-dimensional bar code has the advantages of low cost, convenient transmission, high reliability, strong security and anti-counterfeiting, but the social demand for information is growing, the traditional two-dimensional bar code needs to be constantly improved to meet the people to transfer and store more information requirements. In this paper, a new type of two-dimensional bar code with large capacity is designed based on double Z structure, it not only has the characteristics of simple coding and high information density, but also easy to identify and promote. Results showed that our new code can increase the storage capacity by 4 times in the same format. The experiment showed that the double-z code designed in this paper can store 1500 characters or 700 Chinese characters in a 1-square-centimeter format with 600dpi resolution. In contrast, the information image generated by the usual binary QR code can only store 35 numbers, 9 Chinese characters or 21 letters. It can be clearly seen that the storage capacity of double Z codes under the same format has been greatly improved, which can meet the application scenarios with high information capacity of two-dimensional codes.
