Description
Technical field
The present invention relates to a kind of vena metacarpea identifier, and in particular to vein fingerprint and face composite identification system.
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 vein fingerprint and face composite identification system is provided, solves the movement of vena metacarpea identifier not
Its bottom abrasion can be only caused, is also easy to the connection for damaging vena metacarpea identifier and powering between electric wire and information transmission cable
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：
