Non-contact palm print and palm vein hybrid recognition system

Abstract

The invention discloses a non-contact palm print and palm vein hybrid recognition system, which includes a light guide, an image acquisition module, a light source assembly, a light source control device, a data transmission device, a data processing unit, a light source current duty ratio control device. The light source assembly emit lights which passes through the light guide; the light sourcecontrol device is connected with the light source assembly; the data transmission device is connected with the image acquisition module and the data processing unit; the light source assembly includesa visible light source device and a near infrared light source device; the light source current duty ratio control device is connected with the near infrared light source device; the data processingunit is connected with the light source current duty ratio control device. The image acquisition module comprises a visible light module and a near infrared module. The visible light source device cooperates with the visible light module to acquire palm print images, and the near infrared light source device cooperates with the near infrared module to acquire palm vein images. The system realizesthe combined recognition of palm prints and palm veins, and improves the recognition accuracy and sanitation.

Description

technical field [0001] The invention relates to an identification system, in particular to a non-contact palm print palm vein mixed identification system. Background technique [0002] Biometric identification technology is a discipline in computer science that uses inherent biological characteristics to identify personal identities, access authentication and control, such as fingerprints, palmprints, irises, faces, voiceprints, signatures, gait, etc. As a technology to identify a person's identity with a personalized representation of a person, compared with traditional identity representations such as keys, passwords, and access cards, human biometrics have the advantages of being difficult to forget and forge. Therefore, human biometrics and its Derived products have been developed rapidly, resulting in massive application demands and broad market prospects. [0003] The current mainstream biometric identification technologies have their own advantages and disadvantages:...
