Problems solved by technology

[0003] Usually, fingerprints of multiple fingers are registered in the terminal, and each fingerprint has its own preset fingerprint template set, which contains multiple preset fingerprint templates. Therefore, when fingerprint unlocking is implemented, In the process, the collected fingerprint images are often matched with multiple preset fingerprint template sets corresponding to multiple fingerprints, so the fingerprint unlocking efficiency is low

Abstract

The embodiment of the invention discloses a fingerprint unlocking method and a terminal. The method comprises the steps of obtaining a fingerprint image, and matching the fingerprint image with M preset fingerprint templates of a first type of fingerprint templates in a preset fingerprint template set, wherein the preset fingerprint template set also comprises a second type of fingerprint templates and comprise N-M preset fingerprint templates, the N preset fingerprint templates all belong to the same fingerprint, the N is an integer greater than M, and the M is a positive integer; matching the fingerprint image with the N-M preset fingerprint templates when the fingerprint image matches any one in the M preset fingerprint templates; and realizing fingerprint unlocking when the fingerprint image matches any one in the N-M preset fingerprint templates. Through application of the embodiment of the method and the terminal, the fingerprint image is matched with the first type of fingerprint templates, if the matching is successful, the fingerprint image is matched with the second type of fingerprint templates, so that the matching efficiency can be improved, and the fingerprint unlocking efficiency is improved.

Description

Technical field [0001] The present invention relates to the technical field of electronic equipment, in particular to a fingerprint unlocking and 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. Fingerprint recognition technology is the standard technology on the terminal. Fingerprint recognition technology can be widely used not only for terminal unlocking, wake-up, mobile payment, etc. With the popularity of fingerprint recognition technology, in order to achieve fast unlocking, the unlocking time of the terminal is also a direct concern of terminal manufacturers. [0003] Normally, the terminal will enter the fingerprints of multiple fingers. Each fingerprint has its own preset fingerprint template set. The preset fingerprint template set contains multiple preset fingerprint templates. Therefore, when the fingerprint is unlocked, ...
