What is the generation principle of QR code generator?

Lead: What is the generation principle of QR code generator? The QR code generator is actually the QR code generation software. The working principle of the QR code generator is to input the required information into the QR code generator, generate the corresponding QR code, and then save the application.

What is the generation principle of QR code generator? The QR code is actually a digital matrix consisting of many zeros and 65438+ zeros. This two-dimensional code generation algorithm is to combine the 0 and 1 digital matrix that make up the two-dimensional code. The combination of' 0 and 1 digital matrix is different due to the different information input into the QR code generator, so the generated QR code has various styles.

Step 1: Two-dimensional bar codes record data symbol information with certain geometric figures distributed on a plane (two-dimensional direction) in black and white;

Step 2: Clever use of computer internal logic foundation in code compilation? 0? 、? 1? The concept of bit stream is to represent alphanumeric information with several geometric shapes corresponding to binary.

Step 3: Automatic reading through image input equipment or photoelectric scanning equipment to realize automatic information processing:

It has some commonalities of barcode technology:

1: Each coding system has its own specific character set; Each character occupies a certain width; It has certain verification function.

2. At the same time, it also has the function of automatically recognizing different line information and dealing with the rotation and change of graphics.

Step 3: 2D barcode/QR code can express information in both horizontal and vertical directions at the same time, so it can express a lot of information in a small area.
