Specifically, based on uniqueness of the two-dimensional code and irregularly and randomly distributed bubbles generated in the ceramic firing process, fingerprints of the two-dimensional code image on the ceramic surface are given, and a mobile phone microscope is used for tightly clinging to the position of the two-dimensional code on the original ceramic surface to zigzag and collect the complete two-dimensional code fingerprint image back and forth so as to generate the ceramic panoramic image fingerprint.

Specifically, in step S3, the process of calculating the position similarity includes: comparing the two-dimension code local image fingerprint with the two-dimension code panoramic image fingerprint to determine the position and the angle of the two-dimension code local image fingerprint (because of the uniqueness of the two-dimension code, if the two-dimension code fingerprint identification is needed, the two-dimension code fingerprint to be verified is consistent with the original two-dimension code image, otherwise, the two-dimension code can be verified by scanning the two-dimension code without fingerprint identification); and identifying the bubble position of the two-dimensional code local image fingerprint, and comparing the bubble position with the bubble position corresponding to the two-dimensional code panoramic image fingerprint to obtain the position similarity.
