Problems solved by technology

[0003] In addition to the advantages of being able to quickly and accurately identify data, QR codes also have some problems. To be precise, they have strict requirements on the entire use environment. For example: QR codes cannot change shape and realize nested combinations. Changing to a circle, triangle, or ring will destroy the identification structure of the QR code and make it completely invalid

Abstract

The invention discloses an identification code resisting background character interference and a generation method thereof. The identification code comprises an annular code containing data information and a pattern area arranged in the middle of the annular code. The annular code is obtained by sequentially carrying out binary conversion, graph filling, mask processing, and code assembling and polar coordinate conversion on original data. The annular code is sequentially subjected to positioning and perspective transformation correction, template cutting, polar coordinate conversion, interference processing, mask processing, binary conversion and a binary comparison table to obtain the original data. The pattern is combined with the identification code, so that the background character interference resistance of the identification code can be improved.

Description

Technical field [0001] The invention relates to the technical field of identification code research, in particular to an identification code against background text interference and a method for generating the same. Background technique [0002] QRcode is a widely used identification code. The QRcode identification form includes positioning system, description system, data system and error correction system. The positioning system can be used to quickly find the location of the QR code, and at the same time can perform image projection perspective restoration and check the security of the QR code. After correctly finding the position of the QR code, the description system can accurately understand the data format level information of the QR code. The data system and error correction system can perfectly repair the damaged QR code to a certain extent. The two-dimensional code represents the binary numbers of 0 and 1 through black and white grids of the same size, and then conve...
