Abstract

The embodiment of the invention discloses a fingerprint unlocking method and a terminal. The method is realized in the following steps: obtaining a first fingerprint image; determining the target feature point number of the first fingerprint image; according to a preset mapping relationship between the feature point number and a regulation parameter, obtaining a target regulation parameter corresponding to the target feature point number; according to the target regulation parameter, collecting a second fingerprint image; matching the second fingerprint image with a preset fingerprint template; and if the second fingerprint image and the preset fingerprint template are successfully matched, unlocking the terminal. If the embodiment of the invention is implemented, fingerprint unlocking efficiency can be improved.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a fingerprint unlocking method and a terminal. Background technique [0002] With the rapid development of information technology, the use of terminals (such as mobile phones, tablet computers, etc.) is becoming more and more popular. As a standard technology on the terminal, fingerprint recognition technology can be widely used not only in unlocking, waking up, mobile payment, etc. of the terminal. While the fingerprint recognition technology is popular, in order to achieve fast unlocking, the unlocking time of the terminal is also a direct concern of the terminal manufacturer. [0003] In practical applications, users often find that when the fingers are too dry or too wet, it is necessary to press the fingerprint identification module several times to unlock successfully, thus reducing the efficiency of fingerprint unlocking. Contents of the invention [0004] Embodimen...
