Abstract
The utility model discloses a face recognition access control attendance system. The face recognition access control attendance system comprises a terminal camera, a terminal preprocessor, a communication module, a main processor and a background storage stored with basic feature information data, the terminal camera is used for acquiring images and outputting image information to the terminal preprocessor, the terminal preprocessor is used for extracting face image information from the received image information, executing processing including geometric and gray level normalization of the images and then transmitting the processed image information to the main processor through the communication module, and the main processor is used for reading basic feature information from the background storage, comparing the received image information with the basic feature information, performing recognition processing and storing the received image information and recognition processing results to the background storage. The face recognition access control attendance system is especially applicable to attendance systems with multiple recognition terminals, and is capable of achieving accurate recognition and convenient for information management of the whole attendance system, so that security protection is strengthened.
Description
Technical field
The utility model relates to the recognition technology field in the access control and attendance, particularly a kind of recognition of face access control and attendance system that can be used for the multiple terminals occasions such as routine office work, laboratory.
Background technology
At present, access control and attendance system more and more is used in business administration and other are as in the security system.Existing access control and attendance system adopts the technology of fingerprint recognition more, it does not need the similar certificates such as attendance card, brought convenience for the work attendance personnel, although this access control and attendance mode cost is lower, but there is the lower shortcoming of recognition accuracy in fingerprint recognition, be easy to utilize the false fingerprint of imitation can pass through gate inhibition or work attendance, be unfavorable for management and the security of system of enterprise.Particularly in having the system of a plurality of attendance record terminals, fingerprint recognition is difficult for realizing unified information management.
Summary of the invention
The utility model provides a kind of discrimination higher for the defective of prior art, and be easy to the recognition of face access control and attendance system of unified management, comprise terminal video camera, terminal pretreater, communication module, primary processor and the background memory that stores the foundation characteristic information data; Wherein:
Terminal camera acquisition image, and output image information is to the terminal pretreater, the terminal pretreater carries out pre-service to the image information that receives, and then pretreated image information is transferred to primary processor by communication module; Primary processor reads foundation characteristic information from background memory, and image information and the foundation characteristic information that receives is compared and identifying processing; The while primary processor is with the image information that receives, and the identifying processing result store is to background processor.
As a kind of improvement, the utility model also comprises terminal display, the demonstration of terminal handler control terminal display; Primary processor is sent to terminal handler with recognition result by communication module, and shows by terminal display.In order to be in the staff of end or the result that the work attendance personnel can in time be known work attendance identification, avoid work attendance failure or unidentified personnel to enter the specific region.
Further, the terminal pretreater in the utility model can adopt single-chip microcomputer or DSP to realize.Concrete, the terminal pretreater carries out mainly that some simple people's face head portraits extract, how much and gray scale normalization, and the processing such as compression, and these are processed and all can utilize existing software to realize.
Further, the communication module in the utility model is wireless communication module, can adopt existing wireless communication module product.
The beneficial effects of the utility model are: face recognition technology itself has the higher characteristics of discrimination, the utility model is when being applied to the attendance checking system of many identification terminals, can be on the basis that guarantees recognition accuracy, be convenient to the information management of whole attendance checking system, particularly be used in school's laboratory work attendance, perhaps during the work attendance of large enterprise multiple terminals, can take precautions against by intensified safety.
Description of drawings
Figure 1 shows that the specific embodiment of the utility model system chart.
Embodiment
For content of the present utility model is become apparent more, further describe below in conjunction with the drawings and specific embodiments.
In conjunction with shown in Figure 1, recognition of face access control and attendance system of the present utility model comprises: terminal video camera, terminal pretreater, communication module, primary processor and the background memory that stores the foundation characteristic data; Wherein:
The terminal video camera can be selected existing video camera product, and its collection comprises the image information of facial image, and forwards image to the YCbCr color space from rgb space.Because the distribution of the colour of skin in the YCbCr color space of people's face is relatively concentrated, colouring information can come people's face to a certain extent with most of background segment, so that terminal handler extracts human face image information.The terminal pretreater can adopt single-chip microcomputer or DSP, and in conjunction with existing software engineering, from the image information after the conversion, according to area of skin color human face image information is cut apart and extracted, again the human face image information that extracts is carried out geometry and the pre-service such as gray scale normalization and data compression, prepare for accurately extracting face characteristic.In the pretreated human face image information, comprise according to five rules in three front yards, the coordinate at human eye place and the size of length, the area information at the organ places such as determined eyes, nose, face.
The terminal pretreater transfers to primary processor with pretreated image information by communication module; Communication module can adopt existing wireless communication module, so that system architecture is succinct; Primary processor at first reads foundation characteristic information, and image information and the foundation characteristic information that receives is compared, so that the image information that receives is carried out identifying processing after receiving image information after the processing from background memory; The while primary processor is with the characteristic image information that receives, and the identifying processing result store is to background processor, so that the in the future extraction of data.
Primary processor can adopt computing machine, and in conjunction with contrast, the identification processing procedure of existing techniques in realizing image information and foundation characteristic information.
In addition, primary processor also can be sent to terminal handler with recognition result by wireless communication module, and by display is set with the Identification display result in terminal, so that end staff or work attendance personnel can in time be known the result of work attendance identification, avoid work attendance failure or unidentified personnel to enter the specific region.
When the utility model is specially adapted to the attendance checking system of many identification terminals, can on the basis that guarantees recognition accuracy, be convenient to the information management of whole attendance checking system, and can takes precautions against by intensified safety.
The case of implementation described in the utility model only is better case study on implementation of the present utility model, is not to limit practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be as technology category of the present utility model.
