Non-contact type palm print and palm vein recognition system

Abstract

The invention discloses a non-contact type palm print and palm vein recognition system, which comprises an active light source, an image acquisition device, a data transmission controller and a core processing device. The active light source is used for providing visible light and near infrared light for image acquisition, the image acquisition device is used for acquiring palm print images and palm vein images according to reflecting light, which is illuminated onto a palm of a user, of the visual light and the near infrared light, the data transmission controller is used for transmitting the palm print images and the palm vein images to the core processing device, and the core processing device is connected with the data transmission controller, is used for preprocessing the palm print images and the palm vein images, and then realizes feather comparison of preprocessed images and stored reserved samples so as to realize identification. The non-contact type palm print and palm vein recognition system realizes non-contact type palm image acquisition and recognition, improves palm recognition precision, is safe and sanitary and is convenient in use. Besides, energy consumption is saved, and simultaneously, the service life of the system is prolonged.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a non-contact palmprint and vein recognition system. Background technique [0002] The identification technology based on human biological characteristics is referred to as biometric technology, which is an interdisciplinary subject combining biological information technology and computer technology that has emerged in recent years. The so-called biometric technology refers to the use of the inherent physical characteristics of the human body, such as fingerprints, palm prints, irises, faces, etc., and behavioral characteristics, such as voice, handwritten signature, gait, etc., as personalized representations of people. A technique for identifying a person. Compared with traditional keys, passwords and ID cards and other identity representations, human biometrics have the advantages of not being easily forgotten, lost and forged. Therefore, biometric technology and it...

AI Technical Summary

Problems solved by technology

[0009] In short, there are the following defects in the identification of palm in the prior art: the identification system of palm vein alone has less characteristic information and the identification accuracy is not high; secondly, the identification system using palmprint alone has poor anti-counterfeiting ability; Most of them use contact type, so there are hygienic problems
