Abstract

The embodiment of the invention discloses a fingerprint unlocking method and a mobile terminal. The fingerprint unlocking method comprises the following steps: extracting at least one detail feature point in a fingerprint image inputted by a user; sorting at least one preset fingerprint template according to the quantity of the detail feature points matched with the inputted fingerprint image; successively comparing the inputted fingerprint image with the at least one fingerprint template according to the sorting; and unlocking the mobile terminal when the matching degree between the inputted fingerprint image and at least one fingerprint template reaches a preset matching degree threshold. According to the embodiment of the invention, the matching of the fingerprint template at a higher matching degree is preferably performed by adjusting the sorting of the fingerprint template, the matching speed can be increased, and the efficiency of recognizing the fingerprint is promoted.

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...
