Abstract

The invention discloses a palmar venous authentication device convenient to quickly operate, comprising a palmar venous recognition instrument; a fixed plate is arranged at the bottom of the palmar venous recognition instrument; each end of the fixed plate is provided with a moving plate; a telescopic rod and a guide component having mutually parallel axes are arranged between the fixed plate andeach moving plate; one end of each moving plate far away from the fixed plate is hinged to a clamp plate; a return spring is arranged between each clamp plate and the corresponding moving plate. The clamp plates are clamped to a desk through deformation of the return springs so as to fix the palmar venous recognition instrument to a desktop, moving of the palmar venous recognition instrument during use is avoided, bottom abrasion is avoided, damage of joints of the palmar venous recognition instrument with a power cord and information transmission cables is also avoided, and power acquisitionstability and informant transmission stability are improved for the palmar venous recognition instrument.

Description

technical field [0001] The invention relates to a palm vein recognition instrument, in particular to a palm vein authentication device which is convenient for quick operation. Background technique [0002] The palm vein recognition instrument is an access control machine that uses the principle of palm vein recognition technology to work. Palm vein recognition is a kind of vein recognition, which belongs to biometrics. The characteristic value of the vein distribution map is extracted according to the special comparison algorithm, and the image of the finger, palm and back of the hand is obtained through the infrared CCD camera, and the digital image of the vein is stored in the computer system, and the characteristic value is stored. When comparing veins, take vein images in real time, extract feature values, use advanced filtering, image binarization, and thinning methods to extract features from digital images, compare with vein feature values ​​stored in the host, and us...
