Embodiment Construction

[0020] In the embodiment of the present invention, the pixel points form a code block, and the code block forms a QR code map or image information.

[0021] figure 1 The flow chart of the QR code encoding method provided by the embodiment of the present invention. The embodiment of the present invention is suitable for adding image information that can be used for visual judgment on the basis of the text information stored in the original QR code. The specific steps of the QR code encoding method are as follows:

[0022] Step S101, setting the first QR code image corresponding to the text information as the background image of the target QR code image;

[0023] Using the existing encoding algorithm, the text information used to describe the first thing is encoded to obtain the first QR code image, that is, the first QR code image is the QR code image corresponding to the text information in the prior art, and the embodiment of the present invention will The first QR code ima...

Abstract

Embodiments of the invention provide a coding method and apparatus for QR (Quick Response) codes. The method comprises: setting a first QR code map corresponding to text information to be a background image of a target QR code map; and setting image information to be a foreground image of the target QR code map, so that the text information and the image information are stored in the target QR code map at the same time. According to the embodiments of the invention, the text information is set to be the background image of the target QR code map, and the image information is set to be the foreground image of the target QR code map, so that the target QR code map carries the text information and the image information at the same time, and information types stored in the QR codes are added and diversified.

Description

technical field [0001] Embodiments of the present invention relate to image processing technology, and in particular to a QR code encoding method and device. Background technique [0002] Quick Response Matrix Code (QuickResponse, QR for short) is a black-and-white graphic distributed on a plane with a specific geometric figure according to a certain rule, invented by Denso-Wave Corporation of Japan in 1994. Compared with one-dimensional barcodes, QR codes have the characteristics of easy reading, large data capacity, and strong resistance to damage. [0003] The existing technology describes an item or a thing through text information, and encodes the text information to generate a corresponding QR code, realizing the use of a QR code to identify an item or a thing, and a QR code can be used to uniquely identify an item For an item or a thing, this unique identification can be used for multiple purposes, such as anti-counterfeiting traceability, tracking process, lottery, ...
