Vein-fingerprint-face composite recognition system with automatic light brightness control function

Abstract

The invention discloses a vein-fingerprint-face composite recognition system with an automatic light brightness control function. The system includes a support frame which is provided with a verticaladjusting slot. A sliding block is arranged on the vertical adjusting slot. The sliding block can move along the vertical adjusting slot or be fixed to the vertical adjusting slot. A mounting rod is arranged on the sliding block. The mounting rod is provided with a horizontal adjusting slot. A fixing device is arranged on the horizontal adjusting slot. The fixing device can move along the horizontal adjusting slot or be fixed to the horizontal adjusting slot. The support frame is further provided with lighting equipment which is connected with a controller. The controller is used for controlling the angle and light intensity of the lighting equipment. The system is more convenient to install and more flexible in installation position. The angle and light intensity of the lighting equipmentare adjusted according to the illumination conditions of the external environment so that the vein-fingerprint-face composite recognition system has a better recognition effect.

Description

technical field

[0001] The invention relates to the field of biometric identification, in particular to a vein fingerprint and human face complex identification system that can automatically control brightness. Background technique

[0002] The so-called biometric technology refers to the close combination of computer and high-tech means such as optics, acoustics, biosensors and biostatistics, using the inherent physiological characteristics of the human body such as fingerprints, finger veins, faces, irises, handwriting, voice, gait, etc. and other behavioral characteristics for personal identification. Traditional identity verification methods include identification items such as keys, certificates, and ATM cards, and identification knowledge such as user names and passwords. However, due to the use of external objects, once the identification items and identification knowledge that prove identity are stolen or forgotten, their identity is easy. be impersonated or replace...
