Abstract

A finger vein and knuckle pattern dual-mode biological characteristic acquisition system comprises a frame (1), a main control module (2), an image acquisition module (3), a red light source device (4), a near infrared light source device (5), a light source driving module (6) and a display module (7). According to the method, the influence of the ambient light on the image acquisition is greatlyreduced, the high-quality images of the finger veins and the finger knuckle patterns can be acquired, the acquired finger veins and finger knuckle patterns are consistent in posture, and the subsequent ROI positioning extraction operation is facilitated.

Description

technical field [0001] The invention relates to the technical field of biological feature identification, in particular to a dual-mode biological feature acquisition system of finger veins and finger knuckle patterns. Background technique [0002] The universality and necessity of computers is the inevitable result of the development of today's information technology, which makes the whole society a combination of information and network. How to further strengthen the security of social informatization and network has become the top priority of urgent problems to be solved. , and identity authentication is a basic method used throughout the ages. There are two traditional methods of identity authentication, one is identity authentication based on markers (keys, certificates); the other is identity authentication based on knowledge (passwords, card numbers), but the defects of both are through "Identity authentication, and these extraneous things are easy to be forged or imp...
