Data dot matrix encoding and decoding method and system based on highlighted central pattern and medium

Abstract

The invention discloses a data dot matrix encoding and decoding method and system based on a highlighted central pattern and a medium. The data information is recorded through the data dot matrix, thedensity is high, and the capacity is large. According to the invention, the original data is converted into the bit stream for sub-packaging processing to form a plurality of code block combinations,so that larger-scale data can be accommodated. According to the invention, the code block working area is arranged at the periphery of the central pattern; the distance from the center of the centralpattern to the edge of the central pattern is a first distance; the distance from the center of the central pattern to the edge of the code block working area is a second distance, the ratio of the first distance to the second distance is controlled to be not smaller than 0.618, the man-machine interaction experience is improved through combination of the large-proportion central pattern and thesmall-proportion code block data, and the method can be widely applied to the technical field of data storage.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a data dot matrix encoding and decoding method, system and medium based on a prominent central pattern. Background technique [0002] The one-dimensional and two-dimensional barcodes that people are accustomed to using today are essentially computer digital information, that is, data, which are output according to certain coding rules to form visible graphic dot matrix blocks (which can be called graphic data codes). [0003] With the rapid development of the mobile Internet, more and more people are used to scanning code applications, but the hardware technical conditions of the two-dimensional codes used in the market are very different when they are invented, that is, the past two-dimensional codes mainly rely on Special reading devices (such as scanning guns, card readers, etc.) are used as the "man-machine interface", and the sensor resolution is relatively low. Therefo...

Problems solved by technology

In the actual use of QR code, a small "hole" is cut out in the center of the QR code to fill in the small pattern, which also uses the redundant error correction function in the QR coding scheme, but the small pattern has a small area and cannot be passed through. The image expresses more identification information. If the cutout pattern exceeds the size limit, it will easily lead to the failure of QR code scanning

Therefore, the existing QR code cannot support digital network interfaces such as LOGO, business cards, seals, logos, street signs, warning signs, etc.
