Problems solved by technology

[0003] However, no matter how the basic style of the two-dimensional code changes, when the two-dimensional code is fused with the background image, the basic style of the two-dimensional code will cause a certain loss of information to the background image, so that the content of the background image cannot be fully highlighted, destroying the background The integrity of the image environment color makes it difficult to convey complete visual information

Abstract

The invention provides a two-dimension code image generating method and device. The method comprises the steps of obtaining messages to be coded and a background image, and generating a two-dimension code distribution matrix according to the messages to be coded, wherein the two-dimension code distribution matrix comprises a plurality of basic patterns; obtaining the grey information of the two-dimension code distribution matrix and the grey information of the background image; eliminating at least one basic pattern according to the grey information of the two-dimension code distribution matrix and the grey information of the background image so as to reset the two-dimension code distribution matrix according to the at least one eliminated basis pattern; mixing the rest two-dimension code distribution matrix and the background image together so as to generate a two-dimension code image. The two-dimension code image generating method reduces coverage on the background image so as to further improve the immersion degree of the two-dimension code in the background image, make the background image prominent, and ensure the completeness of the environment color of the background image and the picture harmony sense of the two-dimension code image to a large degree, and increase the display effect of the two-dimension code image.

Description

technical field [0001] The invention relates to the field of computer application technology, in particular to a method and device for generating a two-dimensional code image. Background technique [0002] The pattern of the traditional two-dimensional code is mainly black and white or black and white interlaced, and the pattern style is relatively monotonous. Therefore, there is currently an immersive two-dimensional code, which is to fuse the two-dimensional code with the background image or change the pattern of the two-dimensional code, so as to diversify the style of the two-dimensional code and improve the interest of the two-dimensional code. At present, the immersive two-dimensional code is mainly to integrate the two-dimensional code with the background image whose content can be customized, such as combining the two-dimensional code with the user avatar, the merchant logo image or the product image, so that the two-dimensional code and the image coexist, The obtai...
