Document Type and Number:
WIPO Patent Application WO/2022/068931
Kind Code:
A1
Abstract:
Provided in the present application are a non-contact fingerprint recognition method and apparatus, a terminal, and a storage medium. The method comprises: photographing one or more fingers of a subject to be identified to acquire a finger image of the one or more fingers; on the basis of a finger recognition model, recognising the fingertip position of the one or more fingers in the finger image to acquire one or more fingertip frames corresponding to the one or more fingers, the fingertip frame comprising a fingerprint area from the most distal end of the one or more fingers to a first interphalangeal crease of the one or more fingers; on the basis of the one or more fingertip frames, acquiring from the finger image one or more fingerprint images corresponding to the fingertip position of the one or more fingers; performing image processing on the one or more fingertip images to acquire a fingerprint image; and comparing the fingerprint image with a fingerprint library image to acquire a comparison result, comprising: locally comparing the fingerprint image with a fingerprint library image to acquire a comparison result; or sending the fingerprint image to a server, such that the server compares the fingerprint image with a fingerprint library image to acquire a comparison result. The present application can implement non-contact fingerprint recognition, enhancing the user experience.
