Problems solved by technology

However, the number of fingerprint templates is limited. If the new templates are replaced too frequently, the old templates will be unusable. If all the templates are updated too slowly, it will cause users to be insensitive after a few days of use, which will increase the rejection rate. All templates are randomly replaced in disorder, resulting in the invalidity of the fingerprint learning function.

Abstract

The invention discloses a fingerprint template update method, a fingerprint template update device and terminal equipment. The method comprises steps that a fingerprint image inputted by a user is matched with fingerprint templates inputted in a fingerprint database, and the inputted information corresponding to the fingerprint templates is marked; if a matching degree of the fingerprint image and the fingerprint templates is greater than a preset threshold, whether the quantity of the inputted fingerprint templates reaches a preset threshold value is detected; if the quantity of the inputted fingerprint templates reaches the preset threshold value, to-be-replaced fingerprint templates are deleted from the fingerprint database according to the inputted information corresponding to the fingerprint templates; the fingerprint image is taken as a new fingerprint template to input to the fingerprint database, and the inputted information corresponding to the fingerprint image is further marked. Through the method, the fingerprint templates can be timely and sequentially updated, a false rejection rate is reduced, and validity of a fingerprint learning function and fingerprint identification accuracy are improved.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to a fingerprint template updating method, device and terminal equipment. Background technique [0002] With the continuous popularization of fingerprint recognition, fingerprint recognition can not only be used for functions such as unlocking and waking up mobile terminals, but also an important part of mobile payment. Therefore, more and more attention is paid to the effectiveness and accuracy of fingerprint recognition. [0003] Usually, the fingerprint template will not change after the first registration is completed. If the quality of user registration is high, the recognition rate of subsequent use will be high. If the quality of user registration is low, the subsequent use experience will be poor. It is difficult to guarantee the quality of registration without any training. [0004] In the related art, a fingerprint learning function is proposed, throug...
