Fingerprint registration method and device and terminal thereof
First Claim
1. A fingerprint registration method performed by a mobile terminal, the fingerprint registration method comprising:
- receiving a registered fingerprint image input at an Nth time by a user and retrieving feature points of the registered fingerprint image input at the Nth time, wherein N is a positive integer;
determining whether the registered fingerprint image input at the Nth time and registered fingerprint images input at N−
1 times belong to a same finger based on the feature points of the registered fingerprint image input at the Nth time and feature points of the registered fingerprint images input at the N−
1 times previous to the Nth time;
adding the registered fingerprint image input at the Nth time to a candidate collection of registered fingerprint images if the registered fingerprint image input at the Nth time and the registered fingerprint images input at the N−
1 times belong to the same finger, wherein a fingerprint template is generated correspondingly based on registered fingerprint images in the candidate collection of registered fingerprint images; and
receiving a next registered fingerprint image input at an (N+1)th time by the user, if N is less than a predetermined threshold value and the registered fingerprint image input at the Nth time and the registered fingerprint images input at the N−
1 times belong to the same finger.

Abstract
A fingerprint registration method, device and terminal thereof are proposed. The method includes: receiving a registered fingerprint image input at an Nth time by a user and retrieving feature points of the registered fingerprint image input at the Nth time; determining whether the registered fingerprint image input at the Nth time and registered fingerprint images input at N−1 times belong to a same finger based on the feature points of the registered fingerprint image input at the Nth time and feature points of the registered fingerprint images input at the N−1 times previous to the Nth time; and adding the registered fingerprint image input at the Nth time to a candidate collection of registered fingerprint images if the registered fingerprint image input at the Nth time and the registered fingerprint images input at the N−1 times belong to the same finger.
