Method for generating two-dimensional code

Abstract

The invention belongs to the technical field of two-dimensional codes, and particularly relates to a method for generating a two-dimensional code. The method comprises the steps of (1) determining a functional pattern and a data region R(M)c of a two-dimensional code; (2) dividing the data region R(M)c into pixel matrixes according to black and white pixels of the data region R(M)c, and then calculating different rule patterns formed by the black pixels in the data region R(M)c by using a pattern judgment algorithm; and (3) replacing the different rule patterns with preset pictures. For a new propaganda link, a beautified two-dimensional code picture can be generated immediately according to the method, and the personnel cost and the production time loss of employing an art designer for a long term for realizing the similar effect are greatly saved. In addition, a two-dimensional code generated according to the method is good in anti-counterfeiting performance.

Description

technical field [0001] The invention belongs to the technical field of two-dimensional codes, and in particular relates to a method for generating two-dimensional codes. Background technique [0002] Quick Response Code (QR code), referred to as QR code, is a two-dimensional barcode invented by Densowave Company in Japan in 1994. The QR code was approved by the ISO international standard ISO / IEC18004 in June 2000. The QR code is an open standard and its specifications are public. QR codes usually consist of a series of black and white square modules arranged according to certain rules to form a matrix. The QR code has a larger storage information capacity than the one-dimensional barcode, a rich coded character set, a strong error correction ability, and a unique positioning function that can resist rotation. [0003] With the popularity of smartphones with cameras, QR code applications have become more and more popular, such as electronic coupons, train tickets, QR code p...

Problems solved by technology

This completely manual way of beautifying the QR code consumes a lot of manpower and material resources, and cannot guarantee the correct rate of decoding, and the reuse rate is low

[0007] And with the increasing application of two-dimensional codes, more and more anti-counterfeiting labels based on two-dimensional codes appear on the market, but two-dimensional codes, like digital ones, are a standardized coding specification, as long as the equipment conditions Yes, any mobile phone, scanning gun, and collector can be read, so many times for users, it is a misunderstanding to think that the QR code has anti-counterfeiting properties; counterfeiters only need to obtain a set of QR codes. Code can be counterfeited, so the anti-counterfeiting of traditional QR code is low
