Description
Technical field
The present invention relates to a kind of vena metacarpea identifier, and in particular to is easy to quick operating vena metacarpea authenticating device.
Background technology
Vena metacarpea identifier is the door access machine being operated using palm vein identification technology principle, and vena metacarpea identification is quiet
One kind of arteries and veins identification, belongs to bio-identification, and palm vein identification system is exactly to obtain personal vena metacarpea by hand vein recognition instrument first
Distribution map, from vena metacarpea distribution map according to special alignment algorithm extract characteristic value, by infrared C CD cameras obtain finger,
The image of palm, hand back vein, by the digital picture storage of vein in computer systems, characteristic value is stored.Vein compares
When, vein figure is taken in real time, extracts characteristic value, with advanced filtering, image binaryzation, refinement means to digital image zooming-out
Feature, with the comparison of main frame medium sized vein characteristic value is stored in, vein pattern is matched using the matching algorithm of complexity, so as to right
Individual carries out identity authentication, confirms identity.
When carrying out authentication with vena metacarpea, acquisition be vena metacarpea characteristics of image, it is special existing for ability when being palm live body
Sign.Within the system, the palm of non-living body is to cannot get vein image feature, thus None- identified, so as to also can not just make
It is false.When carrying out authentication with vena metacarpea, acquisition is vein image feature inside palm, rather than the image of palm surface
Feature.Thus, there is no any due to the damage of palm surface, abrasion, drying or the cognitive disorders brought such as overly wet.
Accuracy due to carrying out authentication by vena metacarpea is reachable very, and many departments of government start gradually
Piece identity's certification is carried out using vena metacarpea identifier.When people's decorrelation department goes through the formalities and carries out vena metacarpea certification, people
Be sitting in staff opposite, therefore vena metacarpea identifier is directly placed on desk.And in long-term use, vena metacarpea
Identifier, by the thrust for coming from user, then produces displacement with everyone use.The movement of vena metacarpea identifier
Its bottom abrasion is not only resulted in, is also easy to the company damaged vena metacarpea identifier and powered between electric wire and information transmission cable
Socket part position, cause loose contact between vena metacarpea identifier and corresponding electric wire.
The content of the invention
Present invention aims at offer to be easy to quick operating vena metacarpea authenticating device, the movement for solving vena metacarpea identifier
Its bottom abrasion is not only resulted in, is also easy to the company damaged vena metacarpea identifier and powered between electric wire and information transmission cable
Socket part position, the problem of causing loose contact between vena metacarpea identifier and corresponding electric wire.
The present invention is achieved through the following technical solutions：
It is easy to quick operating vena metacarpea authenticating device, including vena metacarpea identifier, at the bottom of the vena metacarpea identifier
Portion is provided with fixed plate, is provided with movable plate at the both ends of the fixed plate, is provided between fixed plate and movable plate
Axis expansion link and guidance set parallel to each other, the guidance set includes being sequentially connected and the guide cylinder and guiding of coaxial line
Bar, connected close to one end of fixed plate on one end of the guide cylinder and movable plate, on one end and fixed plate of the guide rod
Connect close to one end of movable plate, in the other end insertion guide cylinder of guide rod, and can be moved along the axis of guide cylinder；
