Abstract

The invention discloses a palmprint image acquisition method and a palmprint image acquisition system for palmprint identification. The method comprises the steps of acquiring a palmprint image of a user through a photographing device; prompting the user to adjust the position of a palm of the user so as to enable the palmprint image acquired by the photographing device to meet a requirement on the palmprint image quality. According to the method, the palmprint image acquired by the photographing device is enabled to meet the requirement on the palmprint image quality by prompting the user to adjust the position of the palm, so that the quality of the palmprint image acquired by a non-contact palmprint identification technology is improved.

Description

technical field [0001] The invention relates to biometric identification technology, in particular to a method and system for acquiring palmprint images. Background technique [0002] Due to the characteristics of stability, uniqueness and convenience of biometric features, biometric technology is used as a means of identity verification to gradually replace traditional identification methods such as keys and passwords. Biometric technology refers to the technology of using some biological characteristics of the human body, such as face, iris, fingerprint, palm print, hand shape, etc., to carry out identification technology, which mainly includes: collecting images, extracting biometric information from the collected images, Then the extracted feature information is matched with all or part of the pre-registered feature information in the database, and the authenticated person is authenticated according to the matching result. [0003] Among them, a non-contact palmprint re...
