Problems solved by technology
In the fingerprint unlocking process, the fingerprint image is first obtained, and then the fingerprint image is matched with the fingerprint template. If the match is successful, the unlock is performed. If the match fails, the user is prompted to press the fingerprint recognition module again. However, in the terminal Often there is not only one fingerprint template, but multiple fingerprint templates. In this case, only one matching order is designed for multiple fingerprint templates in the matching process, that is, the fingerprint template that is entered first will be first entered. Matching, in this way, the matching sequence is relatively rigid, thus reducing the fingerprint unlocking efficiency

Embodiments of the present invention provide a method for updating the matching sequence of fingerprint templates and a terminal, wherein the method includes: acquiring a fingerprint image; matching the fingerprint image with N preset fingerprint templates pre-stored in the terminal, the N Each preset fingerprint template in the preset fingerprint templates corresponds to a matching score, and the N is an integer greater than 1; when the fingerprint image is successfully matched with the preset fingerprint template i, adjust the value of the preset fingerprint template i Matching score, the preset fingerprint template i is any one of the N preset fingerprint templates; the matching scores of the N preset fingerprint templates are sorted in order from high to low to obtain fingerprint template matching sequence, the fingerprint template matching sequence is used for the next fingerprint unlocking. The implementation of the embodiment of the present invention can update the matching sequence of fingerprint templates and use them for the next fingerprint unlocking, thereby improving the efficiency of fingerprint unlocking.
Description
technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a fingerprint template matching sequence updating 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, and users have higher and higher requirements for terminals. Favored by major terminal manufacturers. In the fingerprint unlocking process, the fingerprint image is first obtained, and then the fingerprint image is matched with the fingerprint template. If the match is successful, the unlock is performed. If the match fails, the user is prompted to press the fingerprint recognition module again. However, in the terminal Often there is not only one fingerprint template, but multiple fingerprint templates. In this case, only one matching order is designed for multiple fingerprint templates in the matching proces...
