Abstract

The invention provides a two-dimensional code, a two-dimensional code encoding method and device and a two-dimensional code recognition method and device, wherein the two-dimensional code comprises agraph contour area and a graph filling area; the graphic contour area is used for presenting the appearance style of the two-dimensional code; the graph filling area is located in the graph contour area and is formed by repeatedly filling a primitive two-dimensional code; each primitive two-dimensional code is composed of code elements and comprises a positioning area and a data area, the positioning area is used for allowing a reading program to determine the position of each area in the primitive two-dimensional code, and the data area is used for storing user data. The two-dimensional codeprovided by the invention can break through the limitation of a traditional two-dimensional code in appearance and shape, and the two-dimensional code data is hidden in any graphic shape.

Description

technical field [0001] The present application relates to the field of two-dimensional codes, in particular to a two-dimensional code, a two-dimensional code encoding method and device, and an identification method and device. Background technique [0002] In recent years, with the continuous development of graphic coding technology and image processing technology, two-dimensional code technology has developed rapidly, and has been widely used in mobile payment, securities, information traceability, product packaging, Internet of Things and other fields. After decades of development, many different types of two-dimensional codes have emerged, such as QR code (Quick Response Code), PDF147, DataMatrix, Tencent Mini Program Code, etc. [0003] Traditional one-dimensional barcodes and two-dimensional codes usually have fixed shapes, and their appearance shapes are usually limited to fixed shapes such as rectangles or circles. The appearance is very single and lacks diversity. I...
