Embodiment Construction

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0017] The embodiment of the invention discloses a method for generating a QR code image. Such as figure 1 As shown, the method includes the following steps:

[0018] Step S101: acquiring a background image and a first QR code image.

[0019] Generally, both the background image and the first QR code image are square. The background image can be a color image, a grayscale image, and so on. The background image can be selected arbitrarily, for examp...

Abstract

The invention discloses a method and system for generating a QR code image. The method comprises the following steps: adjusting the color of a second square module in a first QR code image; replacingthe second square module with a circular module with a preset radius to obtain a second QR code image; compounding the background image and the second QR code image into a third QR code image; inputting the third QR code image into a style conversion network, and outputting a fourth QR code image; adjusting the second grayscale image of the fourth QR code image into a third grayscale image meetingrobustness constraints; adjusting the color value of a circular module contained in a non-robust third square module in the fourth QR code image to the color mean value of the third square module towhich the circular module belongs to obtain a fifth QR code image; and converting the third grayscale image of the fourth QR code image into a color image to generate a sixth QR code image. The methodhas good effects in the aspects of flexibility, universality, visual quality, user personalized selection and robustness.

Description

technical field [0001] The invention relates to the field of QR code technology, in particular to a method and system for generating a QR code image. Background technique [0002] QR (Quick Response) code is one of the most widely used multimedia information carriers in the world. Ordinary QR codes are composed of monotonous black and white coding modules, which cannot be recognized by the naked eye and have an unattractive appearance. Therefore, in recent years, various technologies for visual optimization of QR codes have begun to appear. However, the QR code images generated by these existing technologies can often only make a single performance (such as flexibility, versatility, visual quality, user personalized selection, robustness) better, and cannot make the above-mentioned various performances better. The overall effect is better. Contents of the invention [0003] Embodiments of the present invention provide a method and system for generating a QR code image, ...
