摘要

Stamp is one of the most distinctive and representative elements in Chinese culture. However, with the gradual advances in science and technology, verification remains to be the only function of the stamp. Today in some important documents, in addition to the stamp, QR codes are widely used to carry information, which makes the layout of the whole document look unsystematic and cluttered. Therefore, this study aims to beautify normal QR codes into Graphic QR codes combining in stamps, and expects to find out the effect of different brightness on the picture on the error rate of QR codes. In this study, QR codes with different information intensities are combined into two stamp images with different brightness through the error diffusion method by using applications then the digital files of the QR-code combined stamp are printed and confirmed for their reading effect. After scanned, the information contained in the printed barcode is recognized through the anchor dots by geometrical transformation, then comparing the error rate with the original QR code's information. The experiment finds that a higher information intensity of the QR code leads to a higher decoding rate. Besides, the content recognition rate of brighter stamp images is better. Therefore stamps with appropriate brightness have been imported to the experiments separately to analyze the effect of different brightness on the picture with graphic QR code error and find out the best position under different conditions. The above findings show that this study effectively integrates the image characteristics and contents of graphic QR codes with different brightness and information intensities, and also combines technology with the stamp image, indicating a new development direction for stamps-the combination of physical stamp and the virtual online space.
