Dot matrix coding substrate and dot matrix coding identification method

Abstract

The embodiment of the invention relates to a dot matrix coding substrate and a dot matrix coding recognition method, the dot matrix coding substrate comprises a plurality of dot matrix coding units, and each dot matrix coding unit comprises a plurality of position coding point units and a plurality of information coding point units; the central connecting lines of the plurality of position codingpoint units form an angle of less than or equal to 90 degrees; wherein the plurality of information coding point units are arranged in an array shape; the number of points in the information coding point unit is different and greater than the number of points in each position coding point unit. According to the dot matrix coding substrate and the dot matrix coding recognition method provided by the embodiment of the invention, the medium is coded by using a fine dot matrix, and superposition display of codes and other information is not influenced; moreover, coding is carried out in a dot matrix mode, the borne coding information amount is large, and the requirement for coding a large amount of complex information by a user can be met.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a dot matrix coding base and a dot matrix coding recognition method. Background technique [0002] With the rapid development of information technology, people are increasingly using computers to produce, process, exchange and disseminate various forms of information. In daily life, people often use coding patterns to embed certain types of information into media such as paper pages, writing boards or equivalents, collect coding pattern information on the media through identification devices, use computers to identify and display through display devices. For example, scan the barcode of the product at the cashier in the supermarket; or scan the QR code when using the mobile terminal for payment. [0003] However, the coding pattern in the prior art is relatively obvious, and when superimposed and displayed with other information, it will block other information and affec...

Problems solved by technology

[0003] However, the coding pattern in the prior art is relatively obvious, and when superimposed and displayed with other information, it will block other information and affect the display effect of other information; moreover, the amount of information carried by two-dimensional codes and barcodes is limited, when the amount of encoded information is large , the coding form of QR code and bar code cannot meet the needs of users
