Two-dimensional code and image fusion method and two-dimensional code

Abstract

The invention discloses a two-dimensional code and image fusion method used for counterfeiting prevention. The method includes the steps of obtaining an image and a two-dimensional code which are to be fused; dividing the image into a plurality of image blocks according to the original information point number of the two-dimensional code, the image blocks and the original information points of thetwo-dimensional code establishing a corresponding relation; performing gradual change processing on a central sub-region of the image according to attributes of the original information points of thetwo-dimensional code; and a non-central region adopts color of corresponding pixels of the image, thereby obtaining the two-dimensional code fused with the image. The two-dimensional code and image fusion method provided by the invention enables other image blocks except the central sub-region of each information point in the two-dimensional code to clearly display information of the image, the central sub-region is subjected to gradual change processing according to the attributes of the two-dimensional code original information points, image information is not completely shielded, the display range of the image itself is expanded, the area of the image that is covered is reduced, the image information is relatively easy to capture, face recognition is relatively accurate, and anti-counterfeiting processing of fields with relatively high security is facilitated.

Description

technical field [0001] The invention relates to a two-dimensional code and image fusion method, in particular to a two-dimensional code and image fusion method for anti-counterfeiting, and at the same time relates to the two-dimensional code and image fusion obtained by the method, belonging to the technical field of information processing. Background technique [0002] With the continuous development of information processing technology, two-dimensional codes have been widely used due to their wide coding range and strong fault tolerance. Ordinary two-dimensional codes record information by using specific geometric figures in black and white patterns distributed on a two-dimensional plane according to certain rules. The information recorded in the two-dimensional code includes data encoding information, calibration information, image finding graphics and positioning graphics information, and error correction level information. This two-dimensional code needs to be scanned ...

Problems solved by technology

However, its disadvantage is that the pattern in the center part is too small, and it is not easy to distinguish it when it is recognized by the length relative to the picture; and the image generation is simple, and the anti-counterfeiting effect cannot be achieved

The second solution is to use two-dimensional code schematic pattern technology, such as figure 2 As shown, extending the periphery of the QR code to the edge of the picture reflects the schematic effect of the picture, but its disadvantage is that it cannot distinguish similar pictures and cannot achieve anti-counterfeiting effects

[0005] However, when the above method is used to process images and two-dimensional codes, the value of each unit in the first area of ​​the two-dimensional code is overlaid into the central sub-image area of ​​the image area corresponding to the unit, only The peripheral image area maintains the original image, and the area covered by the image is relatively large. It is not easy to distinguish when identifying the long-term relative image, and the color distortion of the color photo is too large, making it difficult for the naked eye to compare the QR code embedded with the avatar. Real people, can not achieve a good anti-counterfeiting effect
