Problems solved by technology

The QR code generated by this method without considering the principle of QR code encoding and decoding, in addition to achieving a mediocre beautification effect, will inevitably cause a decline in the decoding rate of the QR code, or even cause it to be undecodeable

Embodiment Construction

[0030] The embodiments of the present invention will be further described below with reference to the accompanying drawings, but the described embodiments of the present invention are illustrative rather than limiting.

[0031] A method for beautifying a QR code after fusing images, specifically comprising the following steps:

[0032] Step 1: Generate a reference QR code

[0033] Step 2: Construct the forward and reverse basis matrix

[0034] Step 3: Generate Transition QR Code

[0035] Step 4: Module attribute judgment

[0036] Step 5: Module Brightness Adjustment

[0037] The generation of the reference QR code described in step 1 is specifically implemented as follows:

[0038] 1-1. For the input background image I of size n×n, grayscale it and obtain the grayscale image I g ;

[0039] 1-2. According to the module length of the QR code, the grayscale image I g Divide into blocks according to the module structure of the original QR code, and calculate the average val...

Abstract

The invention relates to a method for beautifying a QR code after merging images. The generation steps of the invention are as follows: Binarize the input background image to generate a reference QR code; establish a forward base matrix according to the RS code, and generate an inverse QR code through the Gauss Jordan elimination method. Toward base matrix; use the forward and reverse base matrix to flip the modules with high QR code priority in black and white to obtain a transitional QR code image; adjust the brightness of the small squares in the module to judge the module attributes; adjust the brightness of the module and combine the other two Channel to generate beautified QR code images. In the method of the invention, the transitional QR code is realized by modifying the RS data flow, so its own error correction capability will not be lost. At the same time, the Gaussian model is used to fit the decoding method of the decoder and the visual characteristics of human beings to solve the block effect problem in the brightness adjustment, so that the generated QR code has a good visual effect and ensures the stability of decoding.

Description

technical field [0001] The invention belongs to the technical field of QR codes, in particular to a method for beautifying a QR code after fusing images. Background technique [0002] With the advent of the Internet era and the popularization of smart phones, QR codes can be seen everywhere in daily life. At present, QR codes, as one of the entrances to the mobile Internet, have become the most Commonly used QR codes. However, the traditional QR code is composed of disorganized black and white blocks. As a communication medium, it often appears in the display area that cannot be ignored, and the poor visual effect is unsatisfactory. In view of the problems mentioned above, many methods of beautifying QR codes have been born in recent years. These methods mainly beautify the QR code by changing the color of the QR code or the shape of the module. Since the QR code will be scanned in various environments, it is often affected by ambient light, scanning angle, noise interfer...
