Description

New profile picture identification and fingerprint recognition entrance guard device

Technical field: identification of the utility model involvement aspect picture and fingerprint recognition entrance guard device.

Background technology: the prior biological recognition technology mainly contains fingerprint, the eye iris, and technology such as DNA all have higher accuracy, but not directly perceived.Simply,, perhaps only know a dna sample, can not know immediately whom this people is if only see a people's fingerprint or eye iris image, be through just obtaining a result after certain analyses and comparison.This is bigger for the target group, or basic driftlessness crowd's identification is just relatively more difficult.

Summary of the invention:

The purpose of this utility model is to provide a kind of entrance guard device that can carry out face picture and fingerprint recognition.Can not only discern validated user according to user fingerprints, can also discern validated user according to user's face picture, thus the control gate lock-switch, and automatic recording user head portrait and fingerprint graph information.

The identification of face picture is very directly perceived, behind record servant's the face picture, is easy to just know whom this people is.

See Fig. 3, new profile picture identification of the present utility model and fingerprint recognition entrance guard device, it is characterized in that: doorway machine 1 is connected with door lock 2 with PC; Doorway machine 1 comprises: camera 3, fingerprint instrument 4, LCDs 5 and plurality of keys 7 are connected control circuit board 6 respectively.

See Fig. 4, camera 3, fingerprint instrument 4, LCDs 5, control circuit board 6 and plurality of keys 7 aggregate erections are in a doorway machine 1.Its major function is as follows:

1) face picture, fingerprint recognition

Face picture, fingerprint recognition are cores of the present utility model, and its realizes the identification to user fingerprints, face picture, and user's fingerprint, face comprises the time of identification as original records such as data when discern successfully or fail that afterwards generation is discerned.Inquiry turnover entrance guard device personnel's original recorded data.

2) ID management

User's face picture, fingerprint carried out typing so that do authentication and differentiate during identification.

3) record of entering is followed the tracks of

The device manager can follow the tracks of the recorded information of entering of consulting in the certain hour section at any time.

Operating principle: see Fig. 3-4, new profile picture identification and fingerprint recognition entrance guard device are called for short device, down together.

The front end of device is the fingerprint of catching the people by fingerprint identification module, simultaneously by the facial head portrait of camera motion capture personnel, personnel stock fingerprint, the head portrait of the fingerprint that captures, head portrait and typing are in advance compared, if validated user, discern successfully, and control, open door lock, be kept at the database the inside in order to handle inquiry afterwards this fingerprint, head portrait and by the time simultaneously.Fingerprint recognition is handled and is finished in fingerprint module, promptly breaks away from the PC deal with data, and the identification of face picture is handled and must be finished on PC.

Beneficial effect: outstanding advantage of the present utility model, device with face picture identification and fingerprint identification technology pass through rational algorithm integrated after, performance all has remarkable advantages than single employing face picture or fingerprint identification technology, the precision of identification is higher.Increase the traceability of historical record, the convenience of use, improved the safety and the availability of whole device simultaneously greatly.

The outstanding advantage of this device is its anti-fraudulent and tracing property afterwards.The precision of the fingerprint recognition of this device is very high, and its accuracy of system identification is 0.01%, and the accuracy of system identification of face picture is 1%, both combinations, and accuracy of system identification is low-down.Fingerprint personation is very difficult, but extreme case can cut down others' finger down and pretend to be the he or she, but the personation of face picture difficulty more, and this device can distinguishes between photos and its people, similarly is impossible so will palm off my face.Fingerprint has improved accuracy with combining of face picture identification, and has very high anti-fraudulent.This device is in when identification, and the face that whether opens the door all identification person looks like to place on record.Can tracking enquiry if occur any problem so later on, be convenient to trace, and this also is a kind of deterrence means afterwards, can significantly reduce the attempt that nonregistered user is attempted to get by under false pretences.

This device accuracy of identification is very high, is applicable to bank vault, army's ammunition depot, the confidential departments that archive etc. are higher to safety requirements.It is close etc. that this device can be expanded into auxiliary watch-dog, protective device, the bank's wholesale seal of withdrawing deposit.
