Two-dimensional code that can be embedded with large-scale graphics and its encoding and decoding method and device

Abstract

Embodiments of the invention provide a two-dimensional code capable of being embedded with a large-ratio graph as well as a coding and decoding method and device therefor. The two-dimensional code comprises a locator, a control region, a data region and a canvas region, wherein the locator comprises locating information for identifying and locating the two-dimensional code; the control region comprises configuration information for configuring the two-dimensional code; the configuration information comprises two-dimensional code template information corresponding to a two-dimensional code template used with the two-dimensional code; the data region comprises data information corresponding to original information represented by the two-dimensional code; the position and size of the data region are determined according to the two-dimensional code template; and the canvas region is embedded with the large-ratio graph; and the position and size of the canvas region are determined according to the two-dimensional code template.

Description

technical field [0001] Various embodiments of the present disclosure relate to two-dimensional code technology, and in particular to two-dimensional codes capable of embedding large-scale graphics and encoding and decoding devices thereof. Background technique [0002] Two-dimensional bar code (2-dimensional bar code) is to use a specific geometric figure to distribute black and white graphics on a plane (two-dimensional direction) according to certain rules to record data symbol information. Two-dimensional code cleverly utilizes the concepts of "0" and "1" bit streams that constitute the internal logic basis of the computer in the coding, and uses several geometric shapes corresponding to the binary to represent the text and numerical information, and then input it through the image The equipment or photoelectric scanning equipment can be automatically read to realize the automatic processing of information. Therefore, two-dimensional codes have some common features of ba...

Problems solved by technology

[0008] 2. Reduce the error correction ability of the standard QR code in the application

[0010] 1. The image of the embedded QR code must have a part that can be hollowed out, such as Figure 4 The belly of the cartoon duck is hollowed out

[0011] 2. The picture of the embedded QR code cannot be made very small, because the picture needs to be hollowed out before embedding the QR code, and the QR code itself must be of sufficient size to be read by the reading software

[0012] In addition, at present, although the generation and identification of standard two-dimensional codes are an international standard, such standard two-dimensional codes are used in the anti-counterfeiting industry, and there are problems of easy copying and piracy
