Abstract

The embodiment of the invention discloses a fingerprint unlocking method and a relevant product, wherein the method comprises the following realization steps of obtaining a fingerprint image; regulating the direction of the fingerprint image to be identical to the direction of a preset fingerprint template; determining a first center of the fingerprint image and a second center of the preset fingerprint template; dividing the fingerprint image into a plurality of first regions on the basis of the first center and a first blocking mode; dividing the preset fingerprint template into a pluralityof second regions on the basis of the second center and the first blocking mode; parallelly matching the plurality of first regions with the plurality of second regions; and unlocking a terminal whenthe matching of the plurality of first regions and the plurality of second regions is successful. By implementing the embodiment of the invention, the fingerprint matching time can be reduced; the unlocking efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a fingerprint unlocking method and related products. 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 ...
