Processing method and system for two-dimensional code

Abstract

The invention provides a processing method and system for a two-dimensional code. At a two-dimensional code generation device side, the method comprises: receiving to-be-coded data and determining a preset matrix element width value; carrying out processing on the to-be-coded data to generate a two-dimensional code whose matrix element width is equal to one pixel and the matrix element is in a square shape and storing the two-dimensional code in a compression-free picture format, and storing the determined preset matrix element width value into preset information; and when receiving an instruction of sending the two-dimensional code to a two-dimensional code display device, sending the two-dimensional code or the two-dimensional code and the preset information to the two-dimensional code display, thereby extending the matrix element width of the two-dimensional code into the preset matrix element width value and displaying the value by the two-dimensional code display device. According to the method, the storage space occupied by the generated two-dimensional code and the transmission bandwidth occupied by the generated two-dimensional code are reduced. There is no need to support other picture formats and the processor cost for storing and displaying two-dimensional code can be saved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a two-dimensional code processing method and system. Background technique [0002] Two-dimensional code (Two-dimensional code), also known as two-dimensional barcode, is a black and white pattern distributed on a plane (two-dimensional direction) with specific geometric figures according to certain rules. Two-dimensional code is derived from one-dimensional code technology. Compared with the one-dimensional code, the storage capacity of the two-dimensional code has been expanded by dozens to hundreds of times and the security is also higher. In modern commercial activities, QR codes can be widely used in many aspects, such as: product anti-counterfeiting / traceability, advertising push, website links, data downloads, commodity transactions, positioning / navigation, e-commerce applications, vehicle management, information transmission, etc. [0003] Two-dimensional codes can be di...

Problems solved by technology

[0005] 1. Use uncompressed image format (such as BMP bitmap format) to store the QR code without compressing the QR code (such as compressing through winrar, winzip, etc.), this method will waste a lot of space when storing Transmission bandwidth is also wasted during transmission;

[0006] 2. Use the lossless compressed image format to store the QR code. This method additionally needs to support the corresponding lossless compressed image format. Compared with the uncompressed image format, this method will increase the processor overhead during compression processing. ;

[0007] 3. Use a lossy compressed image format to store the QR code, which will inevitably lead to a decline in the image quality of the QR code, which in turn will reduce the readability of the QR code;

[0008] 4. Use the uncompressed image format to store the QR code and then compress the QR code (such as compressing through winrar, winzip, etc.). When receiving this type of QR code and using it, you need to first The code can be used normally after being decompressed. Therefore, this method will increase the processor overhead and increase the complexity of use when performing compression, decompression, etc.

[0009] In short, the existing processing methods for QR codes are not ideal enough
