Abstract

Provided are a multilayer quick response code encoding/decoding method and encoding/decoding device to improve the information capacity contained in the QR code. The method includes: obtaining an image layer number N of a multilayer quick response (QR) code, with the multilayer quick response (QR) code being a multilayer quick response (QR) code obtained by encoding an original quick response (QR) code; acquiring N groups of colour coefficient characteristic values from a bidirectional invertible colour characteristic library, wherein the colour coefficient characteristic values are used for changing the colour parameter of the original quick response (QR) code image layer; and overlaying the original quick response (QR) code image layer according to an agreed colour order using the acquired N groups of colour coefficient characteristic values so as to obtain the multilayer quick response (QR) code image. On one hand, the multilayer QR code image can meet the transmission of a large amount of information, thus improving the transmission efficiency; on the other hand, multiple encryption of the file can be carried out, increasing the security of file transmission.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a multi-layer quick response code encoding and decoding method and an encoding and decoding device. Background technique [0002] The Quick Response (QR) code is a two-dimensional barcode invented by Denso-Wave Corporation of Japan in 1994. The current QR code is square and only available in black and white. At the three corners of the QR code, three small square patterns similar to the Chinese character "Hui" are printed respectively. The small square pattern of three "back" characters can help to identify the inclined angle of the QR code when decoding the QR code. Therefore, the user of the QR code does not need to align when scanning the QR code, that is, the data can still be read correctly regardless of the scanning angle. [0003] It is precisely because QR codes can store more information than ordinary barcodes, and are faster than ordinary barcodes in recognition, QR c...
