Research on Decoding QR Code based on Image Processing Technology

In allusion to the problem of poor encoding effect of the recognition of QR Code restricted by image acquisition devices and affected by the interference of some external factors, the decoding method after pre-processing the image of QR code by image processing technology is studied in this paper. Experiments show that, this method can effectively remove the interference from background and noise, achieving the purpose of accurate, rapid recognition and better decoding effect.
