Abstract

The embodiment of the present invention discloses a fingerprint unlocking method and a mobile terminal, wherein the fingerprint unlocking method may include: acquiring at least one image area containing minutiae feature points from a fingerprint image input by the user; determining the at least one image area contained in the at least one image area minutiae feature points; matching the minutiae feature points contained in the at least one image region with the minutiae feature points in at least one fingerprint template; when the matching is successful, unlocking the mobile terminal. By adopting the embodiment of the present invention, some areas including minutiae feature points are selected from the fingerprint image input by the user to match with the fingerprint template, which reduces the amount of comparison calculation in the matching process, speeds up the matching speed, and improves the efficiency of fingerprint identification.

Description

technical field [0001] The invention relates to the technical field of intelligent terminals, in particular to a fingerprint unlocking method and a mobile terminal. Background technique [0002] With the development of fingerprint identification technology, the application of fingerprint information is becoming more and more extensive. Nowadays, many mobile terminals on the market are equipped with fingerprint identification modules, which can apply fingerprint identification technology to mobile terminals to improve the security of mobile terminals. [0003] Generally, for different application scenarios, the user may set fingerprints of different fingers as templates in different scenarios. Even for the same finger, since the fingerprint images obtained under different input situations are not the same, there may be multiple fingerprint templates corresponding to the same finger, so many fingerprint templates are usually stored in the mobile terminal. In the prior art, wh...
