Abstract
An entrance guard system with portrait recognition function is disclosed. A visitors portrait database is created in advance. The portrait of current visitor is taken by ordinary camera and then converted to digitalized portrait by video card of computer. Obtained digitalized portrait is stored and compared with the portraits stored in said database to find a match. If a matched is found, a signal is sent to controller to unlock the door. Its advantages include non-contact acquisition of portrait, and high safety and reliability.
Description
The present invention relates to a kind of biological detection system based on the portrait comparison, definite saying so discloses a kind of Identification of Images entrance guard device, belongs to electronic access control technology field.
The identity discriminating means of traditional gate control system comprise modes such as password, password, certificate and magnetic card, IC-card, because separability with the identity people, cause forgery, usurp, phenomenon such as decoding, can not satisfy the needs that modern society's economic activity and social safety are taken precautions against fully.And that the biological attribute of human body is people's a body is exclusive, and some biological attribute of people is unique as attributes such as fingerprint, iris, images for Different Individual, it is used can stop with gate control system to forge, usurp, the generation of phenomenon such as decoding.Particularly people's face image has uniqueness and stability, has become known identity identification marker.At present, fingerprint entrance guard system all needs special-purpose image capture device and obtains image, and image acquisition is touch or contact, and is unhygienic, and can bring discomfort to the user;
The present invention discloses a kind of entrance guard system with human image recognition, and purpose is intended to solve the problems referred to above that exist in the existing gate control system.
Technical solution of the present invention is as follows: the portrait database of setting up the particular place visit in advance, obtain visitor's facial image by the digital image acquisition device, the video frequency collection card of machine converts simulated image to digital image and is kept in the computer as calculated, information with the portrait database is retrieved comparison, identification personnel's identity sends to access controller with qualified information, opens door lock by its control, allow legal person to enter, and unauthorized access person is reported to the police.
Below in conjunction with description of drawings the present invention:
Fig. 1 is a structured flowchart of the present invention.
Fig. 2 is a fundamental diagram of the present invention.
Fig. 3 is an access controller schematic diagram of the present invention.
In Fig. 1, core of the present invention is by card reader keyboard 1, access controller 2, total Line converter 3, image collection card 4 and computer 5 consist of; Peripheral components of the present invention is taken the photograph Resemble machine 6, door status switch 7, electric control door lock 8, the button 9 of going out, alarm 10, power down warning 11 compositions such as grade, peripheral components can be by system requirements in market purchasing. Card reader keyboard 1 and gate inhibition Controller 2 is connected, input reference person's numbering and password; Access controller 2 turns to bus Parallel operation 3 links to each other, and transmits the instruction that gate inhibition's states and receiving computer 5 send to computer 5, Computer 5 is by the communication system of serial port and bus converter 3 completes, image acquisition Card 4 is inserted in the pci expansion slot of computer 5, connects the video camera 6 of gathering image. The gate inhibition But the state input of controller 2 receiving gate magnetic switches 7, the button 9 of going out, power down warning 11, And transmit control signal to electric control door lock 8, alarm 10.
Fig. 2 is System Working Principle figure. Obtain people's face figure of visitor by image scanner Picture, the video frequency collection card of machine converts simulated image to digital image and is kept at computer as calculated In, this image is retrieved comparison with the information in the portrait database of setting up in advance, assert Personnel's identity sends to access controller with qualified information, and is by its control opening door lock, fair Permitted legal person and entered, and unauthorized access person is reported to the police.
In Fig. 3, access controller is by control module, input module and power supply three parts structure Become, power supply U5 provides the direct current of 12V/2A, and input/output module comprises three photoelectricity isolation Digital-quantity input terminal U6; Door status switch state, power work state, the button state of going out; Three sub-U4 of relay output end: alarm, power supply door lock, for subsequent use. Control module is by CPU U1, memory U2, bus transceiver U3 form. Its function comprises: receive signal input part Input, and pass to computer; The order of receiving computer, and control signal lead-out terminal.
Set up the standard access database on computers, storage Lawful access person's natural information (as: numbering, name, authority, induction card number etc.) and people's face pictorial information, and visitor's Visitor Logs (as: visitor's image, access time, type of alarm etc.).
The user is obtained people's face image of visitor simultaneously by card reader or keyboard input Customs Assigned Number and password by optical camera or ccd video camera.Converting simulated image to digital image by the video frequency collection card on the computer is stored on the computer.This person's face image is carried out visual preliminary treatment, extract the feature of people's face, the utilization automatic identification algorithm is discerned, is compared with figure information in the database.The result of identification is as the foundation of computer to the access controller issue an order.
By the effective access control of access controller implementation system.Controller can control door on off state and the duty of power supply; Can transmit the input information of card reader and code keypad to computer; Instruction that can receiving computer is carried out and is opened the door and alarm operation.
Good effect of the present invention is: because Identification of Images is to adopt common camera to obtain the image information of people's face, being retrieved as of portrait is contactless, so obtain convenient and healthy, and safe and reliable.Simultaneously Identification of Images can be used with the user password password,, can be widely used on the entrance guard device so improved accuracy of identification greatly.
