Dynamic implicit two-dimensional code and generation and detection method and device thereof

Abstract

One aspect of the present disclosure relates to a dynamic implicit two-dimensional code comprising a sequence of frames, the sequence of frames comprising a cycle of two or more consecutive image frames based on an image, and the image comprising sub-regions corresponding to elements of a two-dimensional code information matrix; and a two-dimensional code position detector in which a change in luminosity information of each sub-region of the image between two or more consecutive image frames of the sequence of frames is based on a value of a corresponding element of a two-dimensional code information matrix. Other aspects of the invention relate to a dynamic implicit two-dimensional code generation and detection method and device, a computer readable storage medium and the like.

Description

technical field [0001] This application generally relates to two-dimensional codes, and in particular to a dynamic implicit two-dimensional code and its generation and detection. Background technique [0002] Two-dimensional code (QR code) is also called two-dimensional barcode, and its full name is Quick Response code (Quick Responsecode). Two-dimensional codes generally use black and white graphics distributed on a plane (two-dimensional direction) according to certain rules to record data symbol information. In terms of coding, the two-dimensional code cleverly uses the concept of a bit stream composed of "0" and "1" that constitutes the internal logic basis of the computer, and uses several geometric figures corresponding to binary to represent the literal value in the above-mentioned way and other information, and automatically read through image input equipment or photoelectric scanning equipment to realize automatic processing of information. Two-dimensional codes g...
