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 present invention discloses a fingerprint unlocking method and a terminal. The method includes: acquiring a fingerprint image, matching the fingerprint image with M preset fingerprint templates of the first type of fingerprint template in the preset fingerprint template set, the preset The fingerprint template set also includes a second type of fingerprint template, which includes N-M preset fingerprint templates, and the N preset fingerprint templates all belong to the same fingerprint, and the N is an integer greater than M, and the M is a positive integer. When the fingerprint image is successfully matched with any one of the M preset fingerprint templates, the fingerprint image is matched with the N-M preset fingerprint templates, and the fingerprint image is matched with the N-M preset fingerprint templates. When any one of them matches successfully, fingerprint unlocking is realized. Through the embodiment of the present invention, the fingerprint image can be matched with the first type of fingerprint template first, and then matched with the second type of fingerprint template if the matching is successful. Therefore, the matching efficiency can be improved to improve the fingerprint unlocking efficiency.

Description

technical field [0001] The 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. 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] 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, During the process, the collected fingerpri...
