Abstract
The present invention relates to finger vein image acquisition methods.The present invention provides a kind of finger vein image acquisition method, the near infrared emission device including placing finger both sides two rows horizontal direction；The inductive switch two that the device of adaptive finger width and startup are taken pictures.The finger venous image that acquisition is generated through infrared light supply irradiation, the image collected is handled.The acquisition mode that the present invention uses makes vein image relatively sharp, coordinates high precision image collecting device, authentication precision index discrimination can be made to be superior to traditional biological feature verification technology.
Description
Technical field
The present invention relates to human body biological characteristics extractions, and in particular to the acquisition and recognition methods of finger venous image.
Background technology
With continuous promotion of the entire society to personnel identity effectiveness of information and accuracy requirement, domestic industry-by-industry pair
The demand growth of effective convenient accurately authentication product is increasingly powerful, and biological identification technology is safety and easily identity is known
Other method.Current biometric discrimination method has fingerprint recognition, recognition of face and iris recognition etc..
With gradually spreading out for various biological identification technologies application, the appearance that the method for more than bio-identification is more or less can not be kept away
The loophole exempted from.However the progress of technology and development, finger vein identification technology are shown one's talent in this field, finger vena identification
Technology has been most convenient in various bio-identifications, the biotechnology solution of reliable and technical relative maturity.
Finger vein identification technology is to absorb near infrared light using the ferroheme in blood and finger its hetero-organization infrared light is easy to
By principle, referred to near infrared light opponent and be irradiated, form naked eyes sightless blood trend on the image sensor
Structural images, foundation of this image as identification.Blood is present in inside skin, can not replicate.The flowing of blood is also
The characteristic that biological living just has, therefore hand hand vein recognition is substantially also vivo identification.
The content of the invention
The present invention be directed in mobile phone venous collection and identification technology, occur at present due to everyone individual difference
The problem of finger thickness, causes extraneous light to be collected and then influences the quality of finger venous image.The present invention is two rows of infrared
Luminous tube is respectively placed on the slidable sliding block of finger both sides（See Fig. 1 sliding blocks 1 and sliding block 2）, each sliding block inside has
The spring of one certain stress（See Fig. 1 springs 1 and spring 2）, such design can ensure the sliding block of both sides with finger
Thickness and move and be close to the both sides of finger.It can ensure that infrared light is emitted directly toward finger first, in addition can also prevent outer
The light in portion enters acquisition system, avoids stray light to the interference of image so as to improve the matter of finger vein image acquisition
Amount is laid a good foundation for subsequent image processing.Two human induction switch below finger are sensing that finger is placed into
Position（See Fig. 2 inductive pick-ups 1 and inductive pick-up 2）While start corresponding image acquisition procedure.The invention adds figure
As the rapidity of acquisition and the accuracy of identification, while the action also avoided due to pressing switch causes flating and then shadow
The problem of ringing Image Acquisition and identification quality.After the completion of finger vein image acquisition, subsequent image processing program complete into
The image procossing of one step.
