Abstract
The utility model relates to an infrared fingerprint recognizer which comprises a casing, a camera and a computer, wherein an equicrural right-angle triple prism of which the two inclined planes are positioned in the casing is installed in a fenestra of a panel of the casing, a fingerprint image camera and an infrared light generator are installed in the casing, an image processing board is respectively connected with the camera and a computer, and a group of fingerprint confirmation buttons are installed on the casing. The infrared fingerprint recognizer has the advantages of simple structure and rapid, convenient and accurate collection, storage, transfer and comparative discrimination of fingerprint images.
Description
This utility model relates to detecting instrument, particularly the fingerprint identifier.
At present the fingerprint identifier has variedly, but its reliability, practicality are all not strong, and reason is that fingerprint picked-up head does not pass a test, and the sampling difficulty causes fingerprint to differentiate distortion.
The purpose of this utility model be for overcome above-mentioned defective, provide the sampling of a kind of fingerprint clear, differentiate fingerprint identifier fast and accurately.
For achieving the above object, the technical solution of the utility model comprises: the computer, housing and the photographic head that include image pick-up card, in the fenestra of case panel, be equipped with a top rib downwards, two inclined-planes are positioned at the intravital prism of shell, one infrared light generator is installed in the housing facing to prism one inclined-plane, one photographic head is housed in the housing, and its camera lens is facing to another inclined-plane of prism; Photographic head connects an image processing board, and this image processing board connects with computer; Housing is provided with one group of fingerprint identification button.
The panel cleaner is housed on the housing of described fingerprint identifier, this cleaner by reciprocating electric, rocker and join the brush bar and constitute.
The several critical pieces of this utility model infrared fingerprint identifier all can buy, so its whole structure is simple; The infrared light of specific wavelength makes the fingerprint image picked-up clear according to the reasonable use that the most responsive light source and prism is provided to photographic head; The application of computer and relevant accessory make fingerprint image collection, store, call and relatively differentiate fast, convenient, accurately.
Below in conjunction with accompanying drawing embodiment of the present utility model is done a detailed description.
Fig. 1 is an infrared fingerprint identifier structural representation;
Fig. 2 is the part of infrared fingerprint identifier top view.
As shown in the figure, this utility model infrared fingerprint identifier has a housing 4 that comprises panel 10, it is downward in panel 10 fenestras the top rib to be installed, two hypotenuses are positioned at a crystal glass isosceles right angle prism 9 of housing 4, infrared light generator of being furnished with infrarede emitting diode 11 is installed in the housing 4 facing to an inclined-plane of prism 9, be satisfied with housing 4 interior CCD photographic head 2 and focal length thereof and adjust camera lens 7 another inclined-plane facing to prism 9, one image processing board 3 connects with video camera 2 by cable and is coupled to computer by cable 1, be fitted with the low-voltage and high-current D.C. regulated power supply 12 of DC5V-12V100W in the housing 4, housing 4 is provided with one group of fingerprint identification knob 15, and panel 10 cleaners are housed.
Said panel 10 cleaners by reciprocating electric 13, rocker 5 and join brush bar 6 and constitute, be buckled with stage clip 14 on the rocker 5, make brush bar 6 near panel 10.The rocker corresponding position that resets is provided with cleaning liquid bath 16 on housing 4, and brush bar 6 contacted with cleaning solution in the liquid bath 16 when rocker 5 resetted.
The used computer of infrared fingerprint identifier of present embodiment is the 386DX type, and computer is furnished with D501 type A/D card as the fingerprint image acquisition card, and these parts and CCD photographic head 2, image processing board 3 all can buy.
This utility model infrared fingerprint identifier by to the picked-up of fingerprint image, store, call and relatively differentiate fingerprint.
1, picked-up comprises reservation fingerprint and the picked-up of waiting to reflect fingerprint, is about to fingerprint 8 by on prism 9 bottom surfaces, under infrared light generator 11 irradiations, absorbs fingerprint images by photographic head 2, and the optical signal of this image is converted to the image digitization coding of the signal of telecommunication.
2, computer is imported and be stored in to the above-mentioned picture coding of storage after image processing board 3 is handled, and presses corresponding fingerprint identification knob 15 in the process.The fingerprint of waiting to reflect also can only be imported and not store.
3, the information of calling the representative particular fingerprint that will desire to call accesses from the Computer Storage storehouse.
4, the fingerprint of relatively will waiting to reflect is made comparisons with the reservation fingerprint that accesses from the Computer Storage storehouse, and computer shows same or not same, makes the discriminating conclusion thus.
