Embodiment Construction

[0065] In the prior art, identification code generators (usually merchants, enterprises, individuals, etc.) use existing identification code generation rules (for example, two-dimensional codes commonly include PDF417, QR Code, Code 49, Code16K, Code One And other rules), encode the content that needs to be provided to obtain the identification code. The identification code is then provided to the identification object (usually the user) to provide content.

[0066] Generally, the identification code can provide non-encoded content in addition to the content corresponding to the encoding, which can be used to remind the user of the purpose of the identification code and the encoded content, so that the user can roughly determine the content contained in the identification code or the type of content contained. Among them, the non-encoded content can be provided to the user in the form of patterns, characters, and texts added to the identification code. For example, the non-encod...

Abstract

The invention discloses an identification code generation method and device and an identification code recognition method and device. When an identification code is generated, the center of a circle is firstly determined, then a plurality of concentric circles and a plurality of position detection patterns on a specified radius are generated according to the center of a circle, coding is performedon each concentric circle by starting from a starting pattern in the position detection patterns, and an identification code is generated. When an identification code is recognized, position detection patterns in acquired images are firstly determined, and then the identification code is recognized from the images by starting from a starting pattern in each position detection pattern.

Description

Technical field [0001] This application relates to the field of information technology, and in particular to a method and device for generating and identifying an identification code. Background technique [0002] Currently, mainstream identification codes are usually barcodes and QR codes. Due to the large amount of data it carries, it can write pictures, audio, video and other information, and its recognition success rate is higher. This makes the application of QR codes wider and gradually becomes users (such as individuals, enterprises, etc.) Etc.) Mainly used identification codes. [0003] Generally, the basic composition of a two-dimensional code includes: a position detection pattern (Position Detection Pattern, also known as a positioning stake), functional data, and a data code. The locating post is used to determine the data storage area of ​​the two-dimensional code (that is, the area of ​​the functional data and the data code) when the two-dimensional code is recogniz...
