[0003] However, in the prior art, the fingerprint unlocking process of the terminal can be divided into three main processes, obtaining the fingerprint image, fingerprint matching (matching the fingerprint image with the preset fingerprint template) and unlocking the terminal. Since the fingerprint image is two-dimensional data, Therefore, it is relatively complicated, and in the process of fingerprint matching, specifically referring to the process of extracting the features of the fingerprint image and the preset fingerprint template, it consumes more time, thus resulting in lower fingerprint unlocking efficiency

The embodiment of the present invention discloses a fingerprint unlocking method, including: when the user touches the fingerprint recognition module of the terminal, using the fingerprint recognition module to collect a plurality of capacitance values; generating a binary fingerprint according to the plurality of capacitance values image; matching the binary fingerprint image with a preset fingerprint template; and unlocking the terminal when the binary fingerprint image is successfully matched with the preset fingerprint template. The embodiment of the present invention also provides a terminal. Before the fingerprint matching, the fingerprint image is binarized, thereby reducing the complexity of the fingerprint image and shortening the time for fingerprint comparison, thus improving the efficiency of unlocking the terminal.
Description
technical field [0001] The invention relates to the technical 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] However, in the prior art, the fingerprint unlocking process of the terminal can be divided into three main processes, obtaining the fingerprint image, fingerprint matching (matching the fingerprint image with the preset fingerprint template) and unlocking the terminal. Since the fi...
