Abstract
In the fingerprint identification system according to the present disclosure, the fingerprint sensor collects multiple frames of fingerprint images sliding-inputted by a user, the judging unit determines whether, among the multiple frames of fingerprint images, there is a first overlap region between a current frame of fingerprint images and a previous frame of fingerprint images; if yes, the judging unit removes the first overlap region from the current frame of fingerprint images and superposes the previous frame of fingerprint images with the current frame of fingerprint images to form a superposed fingerprint image; the judging unit completes judgment of all the multiple frames of fingerprint images to obtain a template fingerprint image; the processing unit saves characteristic points of the complete template fingerprint image. The fingerprint sensor collects a to-be-identified fingerprint image pressing-inputted by the user, and the processing unit determines whether the characteristic points of the to-be-identified fingerprint image match with the characteristic points of the template fingerprint image. When establishing template fingerprint database, the fingerprint identif…
