The encoding method is to compile a string of binary numbers from the text, and then combine the color content of the whole picture with a specific algorithm to encode the binary number string and image information into a group of arrays that can be interpreted by specific rules. Besides being readable by machine and equipment, image array can obtain some or even all text information only through human eye recognition.
Extended data
Three-dimensional code is a data symbol recording information with some artistic geometric figures distributed on the imaging content according to certain rules. In addition to the information that the machine can recognize, it also provides identifiable three-dimensional image information for natural people. In the encoding process, through the logic between the digital information of each pixel in the image and the 0, 1 of the data symbol information, intelligent editing and encoding are carried out in various scientific operation modes.
Because each picture can provide different digital information, this coding can not only greatly improve the visualization effect, but also have its own anti-counterfeiting function. According to the needs of social development, this coding method can also provide three-dimensional digital information for machine recognition.
Three-dimensional code is produced in closed source code, and every three-dimensional code can be inquired in China Coding Center, so as to realize the code filing system, which can be organically combined with numbers, patterns, etc., and has the characteristics of being difficult to forge, high in forgery cost and more secure.
