Abstract
The disclosure relates to the technical field of smart door locks. Disclosed is a method for matching a fingerprint image based on Transformer. The method includes: acquiring a fingerprint image to be matched; obtaining a first feature point set of the fingerprint image to be matched by performing Transformer feature extraction on the fingerprint image to be matched; and generating a matching result by performing, based on a second feature point set of a standard fingerprint image, a preset number of levels of Transformer matches between the first feature point set and the second feature point set. According to the disclosure, global information of a fingerprint can be captured by performing a fingerprint match by using a Transformer algorithm. Thus, an identification failure caused by an abnormality of partial fingerprint information is avoided, and accuracy of the fingerprint match is improved.
