Embodiment Construction

[0043]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.

[0044] 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 on...

Abstract

The invention provides a color two-dimension code recognition method and recognition device. The color two-dimension code recognition method comprises the steps of obtaining a two-dimension code; denoising to obtain a locating area; locating according to the locating area; reading information code elements each provided with a plurality of color quantities from an information area, and outputting coded data after decoding. By the adoption of the technical scheme, the color two-dimension code recognition method and recognition device introduce the color quantities, a new color two-dimension code is redefined by the adoption of the color quantities, the color two-dimension code bearing more code-loaded information can be recognized, therefore, more code-loaded information is obtained, the information memory space is large, the two-dimension code can be used as a character or image carrier, and the very high market application value is achieved.

Description

technical field [0001] The invention relates to a color two-dimensional code, in particular to a method and a device for identifying a color two-dimensional code. 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 of automatic ident...
