Patent ID: 10354117

Abstract:
The present disclosure provides a fingerprint identification method and apparatus. The fingerprint identification method includes obtaining a to-be-identified fingerprint image and extracting first characteristic points of the to-be-identified fingerprint image; determining whether a number of the first characteristic points of the to-be-identified fingerprint image is less than a predetermined threshold: when the number of the first characteristic points of the to-be-identified fingerprint image is less than the predetermined threshold, selecting, a fingerprint template image according to the number of the first characteristic points; extracting second characteristic points in the fingerprint template image matching with the first characteristic points of the to-be-identified fingerprint image; overlapping the fingerprint template image with the to-be-identified fingerprint image according to the first characteristic points of the to-be-identified fingerprint image and the second characteristic points of the fingerprint template image to form an overlapped image; determining a valid coincidence region between the to-be-identified fingerprint image and the fingerprint template image in the overlapped image; and determining whether the to-be-identified fingerprint image matches the fingerprint template image according to the valid coincidence region to generate a matching result and performing fingerprint identification based on the matching result. According to the disclosed method, fingerprint identification with less characteristic points can be realized, thus improving the success rate of the fingerprint identification, and reducing the identification error rate.
