A system for recognizing color three-dimensional codes

Abstract

The invention relates to a system for recognizing colorful three-dimensional codes, and mainly relates to a method for recognizing colorful three-dimensional code information. The method comprises the steps of providing an image to be processed; matching the image to be processed with a reference template so that at least one range to be recognized of the image to be processed can be selected, wherein the range to be recognized comprises a piece of colorful three-dimensional code information and a background pattern; converting the range to be recognized into a chromatic aberration image, converting the chromatic aberration image into an optical density image so that the colorful three-dimensional code information can be salient relative to the background pattern. The invention further discloses a colorful three-dimensional code information detection module and a method for detecting the colorful three-dimensional code information.

Description

technical field [0001] The invention relates to a system for identifying color three-dimensional codes, and belongs to the field of identifying color three-dimensional codes. . Background technique [0002] The color three-dimensional code is a brand-new image information matrix product developed on the basis of the traditional black and white two-dimensional code. It is a unique color image three-dimensional matrix product composed of R, G, B, K, 4-color matrix. It is not an information-portable code itself, it provides fast pointing to background content and two-way management of data. The 32BIT color reading and analysis technology of the color three-dimensional code is the only two patented technologies. It is at the international high-end leading level in coding interface design, information editing and data exchange management. At the same time, because the core technology is in a closed source state, which is different from the open sharing mode of the two-dimensio...

Problems solved by technology

[0004] However, in the existing image processing technology, the separation of the color three-dimensional code information and the background pattern is insufficient, making it difficult to use an automatic method to find out whether there is a color three-dimensional code information in the picture, which will increase the difficulty in identifying abnormalities, so How to provide a method for identifying color three-dimensional code information, a color three-dimensional code information detection module and a method for detecting color three-dimensional code information can reduce the difficulty in identifying abnormalities, which has become one of the important topics
