Abstract

The present invention provides a correction method, device and terminal of fingerprint images. The correction method of the fingerprint images comprises the steps of obtaining the information of the pre-stored non-fingerprint images; acquiring the fingerprint images; and correcting the fingerprint images according to the information of the non-fingerprint images. According to the method of the present invention, the non-fingerprint image parts in the acquired fingerprint images can be removed, and the accuracy of the acquired fingerprint images is improved, thereby improving the fingerprint identification effect.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to a method, device and terminal for correcting a fingerprint image. Background technique [0002] Fingerprint recognition technology is widely used in related fields such as smart terminals, electronic security, and public security fingerprint collection systems, and has become one of the most important solutions for identity authentication. At present, fingerprint sensing technology has basically belonged to the standard configuration of smart terminals. Usually, on a smart terminal, the fingerprint sensing technology is realized by using a fingerprint module, which includes a group of fingerprint sensor units. In order to identify the location of the fingerprint module, a pattern will be silk-screened on the cover plate corresponding to the fingerprint module. At the same time, smart terminal manufacturers also have the need to silk-screen their own logo patte...
