Abstract

The embodiment of the invention provides a fingerprint verification method and device based on four-connected-finger fingerprint image acquisition. The method comprises: calling a camera to take a picture, and acquiring a four-connected-finger fingerprint image; carrying out segmentation processing on the four-connected-finger fingerprint image to obtain fingerprint images of four fingers respectively; respectively carrying out image resolution processing on the fingerprint images of the four fingers; and performing fingerprint verification according to the fingerprint images of the four fingers subjected to the image resolution processing. According to the fingerprint verification method and device based on four-finger fingerprint image acquisition, the camera is called to take pictures to obtain the four-finger fingerprint image, fingerprint verification is carried out after segmentation processing and image resolution processing are carried out, fingerprint verification convenienceis greatly improved, and fingerprint verification precision and reliability are effectively improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of image processing, and in particular to a fingerprint verification method and device based on four-finger fingerprint image collection. Background technique [0002] Biometric identification is a widely used identity verification technology. At present, fingerprints, faces, irises, etc. are widely used. These technologies have their own advantages and disadvantages. Face verification technology is easy to use. Generally, there are cameras on mobile phones, and it is easy to collect face images. However, faces change greatly with age, and the accuracy decreases significantly. Iris collection is not friendly, and there is no collector on many mobile phones and other devices, which limits many applications. [0003] Fingerprint verification technology has high precision, but some require on-site fingerprint collectors to collect fingerprints, which limits the application of some rem...
