Abstract
The utility model discloses a face recognition access control system, which comprises a processor, a storage, a flash memory, a loudspeaker, a connector, a camera module, a display screen, a keyboard, a clock chip and a card reader. The processor is connected with the storage, the flash memory, the loudspeaker, the connector, the camera module, the display screen, the keyboard, the clock chip and the card reader respectively. The camera module comprises a plurality of near-infrared light emitting diodes and two infrared camera heads, wherein the near-infrared light emitting diodes are distributed around the infrared camera heads in a rectangular form densely, and the central wavelength of the near-infrared light emitting diodes is 850mm. The face recognition access control system is convenient in installation and use and short in time for recognition, reduces refuse and error rate greatly, eliminates card reading substitute thoroughly, and adopts automatic non-contact face recognition to check and identify identification of irrelevant personnel automatically, complete access control for personnel, limit access of irrelevant personnel, display face images in real time and identify checking personnel quickly.
Description
Technical field:
The utility model relates to a kind of gate control system, relates in particular to a kind of human face identification work-attendance checking gate control system.
Background technology:
At present, attendance recorder has the paper card work attendance gate inhibition of beating, IC-card work attendance gate inhibition, fingerprint attendance gate inhibition and human face identification work-attendance checking gate inhibition etc.Beat paper card work attendance gate inhibition and IC-card work attendance gate inhibition and need put papery or electronic attendance card in addition, not only use cost is higher, and the main problem that also exists is can't stop for checking card phenomenon.
The fingerprint attendance gate inhibition is subjected to that fingerprint pollutes, the influence of some extraneous factors such as impaired, makes its limitation bigger, simultaneously, because fingerprint attendance machine is a contact, the probability of communicate illness increases greatly, and fingerprint also belongs to individual privacy, takes the fingerprint, the suspicion of invasion of privacy is also arranged, now, some human face identification work-attendance checking gate inhibitions have also appearred, but because the influence that disturbed by visible light, it is long to have recognition time, refuses to recognize rate and the high shortcoming of misidentification rate.
Light is the key factor that influences discrimination in the prior art, since with traditional visible light as light source, then when extraneous light is more weak, need to improve the time shutter, and images acquired is slow, and problems such as picture quality is not good appear easily, therefore, the light source that is used for man face image acquiring identification module mostly is simple light source, as UV and IR, and abandon visible light, yet at the simple light source of indoor environment with respect to other light sources, its content is lower, also be difficult to the image effect that reaches satisfied, recognition of face equipment and fingerprint identification device all are mature technologies of the prior art, but in the prior art, also do not have the equipment of comprehensive face recognition technology of energy and fingerprint identification technology to occur.
The utility model content:
The purpose of this utility model is to be used for remedying the prior art face identification system to refuse to recognize rate, the high some shortcomings of misidentification rate, and provide a kind of modern design, simple in structure, adopt nearly ruddiness imaging, make the interference of visible light drop to minimum, show facial image in real time, quick identification work attendance personnel's identity, thoroughly refusal is for the human face identification work-attendance checking gate control system of the phenomenon of checking card.
To achieve these goals, the technical solution of the utility model is as follows:
The human face identification work-attendance checking gate control system, this system comprises processor, storer, flash memory, loudspeaker, connector, shooting module, display screen, keyboard, clock chip and card reader, and described processor is connected with storer, flash memory, loudspeaker, connector, shooting module, display screen, keyboard, clock chip, card reader respectively.
Described shooting module comprises several near-infrared luminous diodes and 2 infrared cameras, and described near-infrared luminous diode is rectangle dense distribution around infrared camera.
The centre wavelength of described near-infrared luminous diode is 850nm.
The utility model human face identification work-attendance checking gate control system modern design, simple in structure, compared with prior art have installation, easy to use, recognition time is short, greatly reduce refuse to recognize, the misidentification rate, thoroughly refusal generation the phenomenon of checking card, make attendance management convenient, light.And the utility model adopts noncontact, Automatic face recognition, the identity of checking automatically, discriminating unrelated person, finish discrepancy personnel's access and exit control, limit entering of unrelated person, and make the interference of visible light drop to minimum, show facial image, quick identification work attendance personnel's identity in real time.
Description of drawings:
Further specify the utility model below in conjunction with the drawings and specific embodiments.
