Embodiment Construction

[0064] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

[0065] A new type of matrix two-dimensional code, also called Zhuoxin code, such as figure 1 As shown, its symbol is composed of four symbol modules of image finding graphics, functional information graphics, correction graphics, auxiliary correction graphics, data coding and error correction coding. The image-finding graphics are respectively set at the four corners of the rectangular area of ​​the new-type matrix two-dimensional code. Each image-finding graphic is composed of polygons of dark modules. Among them, except that the image-finding graphic in the lower right corner is a square, the other three top corners The image finding figures at the corners are all "L" type, and the side lengths of the "L" type image finding figures and the square image finding figures are equal. The correction figure is a box made up of dark modules and set with...

Abstract

The invention relates to novel array-type two-dimension code encoding and decoding methods. The encoding method includes converting information codes into data codes; generating error-correcting codes; calculating dimension parameter of symbols of two-dimension codes; generating view finding graphics, correcting graphics and auxiliary correcting graphics and setting the same in a rectangular area; setting functional information into the rectangular area; and setting the data codes and the error-correcting codes into the rectangular area. The decoding method includes preprocessing images of two-dimension codes; finding view finding images in the symbols of the two-dimension cods; acquiring version number, error correcting grade and mask information; acquiring information of the data codes and the error-correcting codes; removing mask; correcting to obtain recovered data codes; and converting data codes into information codes. The novel array-type two-dimension code encoding and decoding methods are reasonable in design, increase compactness of the symbols of codes, so that more effective data can be accommodated in a limited symbol area as much as possible. Further, reading speed and damaged resistance capacity are improved, and decoding efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of two-dimensional codes, in particular to a method for encoding and decoding novel matrix two-dimensional codes. Background technique [0002] Bar code technology is an emerging technology developed on the basis of computer technology and information technology that integrates coding, printing, identification, data collection and processing. The barcodes usually printed on commodity packaging are ordinary one-dimensional barcodes. One-dimensional barcodes have the following disadvantages: the data capacity is small, and the character set that most one-dimensional barcodes can represent is only 10 numbers, 26 English letters and some special characters; the size of barcode symbols is relatively large, that is, the space utilization rate Lower; the barcode cannot be read after it has been damaged, etc. In daily applications, once a one-dimensional barcode is used to represent Chinese characters, it is very ...
