Problems solved by technology

The disadvantage of the first solution is that you need to press the fingerprint sensor multiple times to register the fingerprint template during registration, resulting in poor user experience; the disadvantage of the second solution is that you need to slide your finger on the fingerprint sensor during identification without pressing the fingerprint sensor. convenient

Embodiment Construction

[0027] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar modules or modules having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all changes, modifications and equivalents coming within the spirit and scope of the appended claims.

[0028] In the field of mobile terminals, fingerprint identification technology has been widely used. Taking the smart phone application scenario as an example, the user selects a finger to register on the smart phone according to his own usage habits, that is, the fingerprint sensor on the smart phone collects the user's fingerprint image and saves it as a fingerprint template;...

Abstract

The invention provides a fingerprint identification method, device and terminal. The fingerprint identification method comprises the following steps: acquiring m pieces of fingerprint sliding image sequences; splicing m pieces of fingerprinting image sequences into fingerprint images S1, S2, ..., Sm; the fingerprint templates T1, T2, ..., Tn are obtained by matching the fingerprint image with the fingerprint templates T1, T2, ..., Tn. The invention combines sliding registration and pressing recognition, sliding registration and then merging the acquired fingerprint image sequence into large fingerprint images S1, S2, ..., Sm, and then fingerprints used for pressing recognition are cut out in these fingerprint images. The user can finish the registration of the fingerprint template by sliding the finger at the time of registration, and only need to press the fingerprint once to complete the fingerprint recognition, and the organic integration of the prior art fingerprint identification scheme is realized.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to a fingerprint identification method, device and terminal. Background technique [0002] In recent years, with the popularization and application of mobile terminals such as smartphones, correspondingly, fingerprint recognition technology has also developed rapidly in the field of mobile terminals, involving functions such as fingerprint unlocking and fingerprint payment. [0003] In the actual fingerprint application scenario, users will face two fingerprint identification schemes: the first one is to press to register and press to identify; the second is to slide to register and slide to identify. The disadvantage of the first solution is that you need to press the fingerprint sensor multiple times to register the fingerprint template during registration, resulting in poor user experience; the disadvantage of the second solution is that you need to slide your ...
