Abstract

The invention discloses an image processing method and device for fingerprint identification. The method comprises the following steps: acquiring a non-contact fingerprint image; and performing imagepreset processing on the non-contact fingerprint image to enable the non-contact fingerprint image to simulate a contact fingerprint image, the image preset processing at least comprising image enhancement processing. According to the invention, the technical problem of poor effect when a non-contact fingerprint uses a universal identification algorithm is solved. According to the invention, the fingerprint image enhancement processing is realized when the fingerprint image is acquired, so that the fingerprint information can be accurately and comprehensively acquired.

Description

technical field [0001] The present application relates to the field of image processing, in particular, to an image processing method and device for fingerprint identification. Background technique [0002] Fingerprint identification technology, with contact or non-contact methods. [0003] The inventors found that due to light changes or finger curvature, it is impossible to obtain fingerprint information comprehensively and accurately when using conventional image enhancement processing methods. Further, it will also cause inaccurate fingerprint identification results. [0004] Aiming at the problem of poor fingerprint identification effect in related technologies, no effective solution has been proposed yet. Contents of the invention [0005] The main purpose of the present application is to provide an image processing method and device for fingerprint identification, so as to solve the problem of poor fingerprint identification effect. [0006] In order to achieve t...
