Embodiment Construction

[0023] 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.

[0024] 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 discloses a generating method and a generating device for a grey two-dimensional code, wherein the generating method comprises the following steps: pre-setting a recognition zone of a two-dimensional code, wherein the recognition zone comprises a positioning zone and an information zone; pre-setting grey-scale number of the two-dimensional codes; a coding step of coding the stored information to generate a plurality of information code elements with a plurality of gray scales; and outputting the recognition zone of the stored information. According to the scheme, the grey two-dimensional code is generated and existing scanning hardware can be effectively utilized to obtain more code-loaded information, so that the information storage content is high, defects of a colorful two-dimensional code are avoided, realization in presswork is facilitated, precise recognition is facilitated, the grey two-dimensional code can be used as a character carrier, and the market application value is very high.

Description

technical field [0001] The present invention relates to the improvement of two-dimensional codes, in particular to a method and device for generating gray two-dimensional 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 of ...
