Embodiment Construction

[0020] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0021] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the technical field of the invention. The terms used in the description of the present invention in this specification are o...

Abstract

The invention provides a method for generating a color multi-order invisible image code. The method comprises the following steps: acquiring image data and information data; and coding the information data according to the original color distribution of the image data to generate an image code with the original color distribution. By adopting the scheme, the image code with the original color distribution is generated according to the original color distribution of the image data, so that a two-dimensional code can display an image and bear more information, has large information storage volume, can be used as a character or image carrier and has the advantage of naked eye identifiability, the representation form of the two-dimensional code is fitter for the practice, instead of various existing small grids or mosaic, and the ornamental value is higher.

Description

technical field [0001] The invention relates to the technical improvement of two-dimensional codes, in particular to a method for generating color multi-level invisible image codes. Background technique [0002] Two-dimensional bar code / two-dimensional bar code (2-dimensional bar code) records data symbol information with a specific geometric figure distributed in a plane (two-dimensional direction) according to certain rules; Using the concepts of "0" and "1" bit streams that constitute the logical basis of the computer, using several geometric shapes corresponding to binary to represent text and numerical information, automatic reading through image input equipment or photoelectric scanning equipment to achieve Automatic processing of information: it has some common features of barcode technology: each code system has its specific character set; each character occupies a certain width; it has a certain verification function, etc. At the same time, it also has the function...
