Embodiment Construction

[0044] The technical solution of the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0045] First, define the following "dark" and "light", the "darkness" is determined by the background. Colors different from the background are collectively referred to as "dark"; colors similar to the background are collectively referred to as "light".

[0046] Through the "multi-color" and "dynamic" processing of ordinary two-dimensional codes, a dynamic two-dimensional code is designed so that it can transfer the amount of data with the help of color display equipment and color camera equipment that have gradually become popular. Larger information, such as ordinary files, etc.; streaming media, such as music, etc. can also be delivered.

[0047] Multi-color: refers to the number of colors constituting the two-dimensional code is greater than or equal to 2, such a two-dimensional code is called a multi-color two-dimensional ...

Abstract

The invention discloses a dynamic two-dimension code which is characterized by comprising at least two frames of two-dimension codes. The two-dimension codes are displayed continuously in a certain frame rate in unit time. Each frame of two-dimension code comprises a position detection pixel point (1) used for detecting boundary position of each frame of two-dimension code and a data area (4). The number of colors forming the data area is larger than or equal to 2. The frame rate is smaller than or equal to half of that of a shooting device. In addition, the dynamic two-dimension code further comprises a frame odd-even check pixel point (5) used for distinguishing any two continuous frames and judging whether image tail happens or not, a brightness detection area (2) used for detecting brightness distribution of each frame of two-dimension codes and a row / line data odd-even check area (3) used for reducing error probability of dynamic two-dimension code information.

Description

Technical field [0001] The invention belongs to the field of information security, and particularly relates to a dynamic two-dimensional code and a decoding method thereof. Background technique [0002] Two-dimensional code, also known as static two-dimensional bar code, static two-dimensional bar code was first invented in Japan. It uses a certain geometric figure to record data symbol information in a black and white pattern distributed on a plane (two-dimensional direction) according to a certain rule. In the code preparation, clever use of the concept of "0" and "1" bit streams that constitute the internal logic of the computer, using several geometric shapes corresponding to the binary system to represent text and numerical information, through image input equipment or photoelectric Scanning equipment automatically reads to realize automatic information processing. It has some common features of barcode technology: each code system has its own specific character set; each c...
