Method for generating dot matrix pattern capable of recording multiple-bit information

Abstract

The invention relates to a method for generating a dot matrix pattern capable of recording multiple-bit information in the field of information processing. According to the method, a point with a website can record the multiple-bit information, only one reference dot matrix line needs to be set on a 45-degree inclination angle, correction of position printing errors on a printing machine can be achieved, and efficiency of information recording can be improved. The invention also provides another dot matrix pattern capable of recording the multiple-bit information. The gray value of the dot matrix pattern is only 1 / 4 the maximum gray value of a common two-dimensional bar code, in addition, the information amount is large, network addresses, anti-fake information and the like can be hidden in a commodity logo, the dot matrix pattern capable of recording the multiple-bit information is especially suitable for being recognized and read by public cell phones and can serve as a network inlet of Internet of Things, and any commodity can be connected with the network. The invention further provides a method for obtaining randomly-distributed variable information only through common printing, therefore, printing cost is reduced, anti-fake grades are improved, and popularization is facilitated.

Description

technical field

[0001] The invention belongs to the field of information processing, in particular to a method for generating a lattice pattern capable of recording multi-bit information. Background technique

[0002] With the rapid development of computer information network technology, the Internet of Things technology with code, mobile phone reading and network as the core is developing vigorously with each passing day.

[0003] In Japan, as the latest two-dimensional barcode, it is possible to directly record large-capacity sound data, and a patent called dot-matrix code, which uses unlimited combinations of codes distributed in several two-dimensional rectangular lattices, was published: "Optical A reading device for readable two-dimensional barcodes" (Japanese Patent Laid-Open No. 2005-243047). Although the use of this code can directly record the sound on the code, but due to the large volume of sound data, the area of ​​the code is relatively large due to the large ...
