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 imag…
