Classification of QR codes
In the code compilation clever use of the internal logic of the computer constitutes the basis of the concept of ‘0’, ‘1’ bit stream, the use of a number of binary corresponding to the geometric form to represent the text numerical information, through the image input equipment or photoelectric scanning equipment automatically Read by the image input equipment or photoelectric scanning equipment to achieve automatic processing of information. In many kinds of two-dimensional bar code, commonly used code system: Data Matrix, Maxi Code, Aztec, QR Code, Vericode, PDF417, Ultra code, Code49, Code 16K, etc., QR Code code was invented in 1994 by the Japanese company DW. QR code comes from the abbreviation of "Quick Response" in English, which means quick response. It originated from the inventor's hope that QR codes can quickly decode their content.QR code is most commonly used in Japan, South Korea; and for the most popular two-dimensional space bar code in Japan. However, the security of QR codes is also being challenged, with malware and viruses becoming a stumbling block on the road to QR code popularity. Developing and preventing the misuse of QR codes is becoming an urgent issue. Each code system has its own specific character set; each character occupies a certain width; has a certain check function, etc.. At the same time, it also has the function of automatic identification of information on different lines and the handling of graphic rotation changes and other characteristics.
QR codes are a more advanced bar code format than 1D codes. A 1D code can only express information in one direction (usually horizontal), whereas a 2D code can store information both horizontally and vertically. One-dimensional codes can only consist of numbers and letters, whereas 2D codes can store information such as Chinese characters, numbers and pictures, making 2D codes much more versatile.
2D bar codes/QR codes can be divided into stacked/rowed 2D bar codes and matrix 2D bar codes. Stacked / rows of two-dimensional bar code form is a one-dimensional bar code stacked by a number of rows of truncated; matrix two-dimensional bar code in the form of a matrix composition, in the matrix of the corresponding element position with the ‘point’ that the binary ‘1’, with the ‘Empty’ means binary “0”, “point” and “empty” arrangement of the code. The principle of QR code can be told from the principle of matrix QR code and the principle of determinant QR code.
Stacking/Row arrangement
Stacked/row arranged two-dimensional bar codes, also known as stacked two-dimensional bar codes or layer arranged two-dimensional bar codes, are encoded based on one-dimensional bar codes and stacked into two or more rows as needed. It inherits some characteristics of one-dimensional bar codes in coding design, verification principles, and recognition methods, and the recognition equipment is compatible with bar code printing and one-dimensional bar code technology. However, due to the increase in the number of rows, it is necessary to determine the rows, and its decoding algorithm and software are not completely the same as one-dimensional bar codes. Representative row arranged two-dimensional bar codes include Code 16K, Code 49, PDF417, MicroPDF417, etc.
Matrix QR code
Matrix two-dimensional bar code (also known as checkerboard two-dimensional bar code) is encoded in a rectangular space through the different distributions of black and white pixels in the matrix. At the positions of the corresponding elements in the matrix, the appearance of points (squares, circles, or other shapes) represents binary "1", and the absence of points represents binary "0". The arrangement and combination of points determine the meaning represented by the matrix two-dimensional bar code. Matrix two-dimensional bar code is a new type of graphic symbol automatic recognition and processing code system based on computer image processing technology, combination coding principles, and other foundations. Representative matrix two-dimensional bar codes include Code One, Maxi Code, QR Code, Data Matrix, Han Xin Code, Grid Matrix, etc.
The commonly used code systems include PDF417 QR code, Data matrix QR code, QR code, Code 49, Code 16K, Code one, etc. In addition to these common QR codes, there are also Vericode barcode, Maxi code bar code, CP bar code, Coda block F bar code, Tianzi code, Ultra code bar code, and Aztec bar code.
