Abstract
The present invention relates to a face image identification entrance guard and work attendance checking system. A head image of a person is dynamically captured by a CCD camera which is connected with a computer; the head image is compared with a head image which is previously inputted into a database so as to make judgement, determine whether the person is allowed to pass, and work out work attendance and work attendance statistics to manage work attendance. The face image identification entrance guard and work attendance checking system is suitable for a WINDOU95/98NT operating system; the time for positioning the face is about 50 to 300 milliseconds; the time for identification and judgement is less than or equal to 1 second; the identifying precision is more than or equal to 99%. The system has the advantages of low cost and no strict requirements for operating conditions, such as the background of a character, light rays, postures, etc., and adjustable parameters, such as identifying precision and identifying time; the system is suitable for various applying occasions.
Description
The present invention relates to utilize computing machine that the person of being identified is carried out face picture identification, differentiate and checking judges, make corresponding attendance record and work attendance statistics.
Prior art Chinese patent application numbers 95190389, publication number 1128006, title: be used to discriminate one's identification card, credit card, discern, the biometric security process of passport and face recognition, be mainly used in discriminate one's identification card, credit card etc., and the making of I.D., credit card.And be not used in work attendance and gate inhibition.
The object of the present invention is to provide the method for a kind of face image identification entrance guard system.
The present invention also aims to provide the method for a kind of picture identification attendance checking system.
Another object of the present invention is to provide the device of above-mentioned face image identification entrance guard and attendance checking system.
Technical solution of the present invention is as follows:
The method of face image identification entrance guard and attendance checking system is divided into gate inhibition and work attendance two parts:
Gate control system partly comprises:
This partial function be to catch facial image and with database in associated profiles compare, by the acceptance value that the system manager sets make " by " (unblanking) or " refusal " judgement, write down source book such as time under the above-mentioned state, litigant's facial photo simultaneously.Concrete workflow is as follows:
After pressing the push button exciting system by the door person, identification work attendance of face picture and gate control system are ceaselessly searched for face image automatically in image data stream, when a similar nose shape object occurs, whether automatically use polytype matching algorithm to judge really has a face in that position, these algorithms can accurately detect many faces that occur simultaneously, and can determine their accurate position;
In case detect a face, the image of this face will be separated from background, this width of cloth image will recover its size, light, expression and attitude through a series of special disposal subsequently;
To recover normal face image and convert a kind of being called " face line " numerical coding (Faceprint) in internal system, the technology of a certain being called " local feature analysis (Local Feature Analysis) " is adopted in this conversion, and this numerical coding (Faceprint) has comprised the peculiar information of every face;
By existing " face line " in " the face line " obtained in real time and the database discerned, relatively, and by the acceptance value that the system manager sets make " by " (opening the door) and " refusal " judgement;
Write down the source book such as time, litigant's facial photo of above-mentioned incident;
Work attendance management system comprises:
According to " work attendance/by " raw readings that writes down in the preceding paragraph and conditions such as daily schedule that the keeper arranged the employee is carried out the work attendance statistics that " being late ", " leaving early ", " overtime work " reach " normal work and rest ".
Face image identification entrance guard of the present invention and attendance checking system device are as follows:
The PC computer of a band WINDOWS/95/98NT operating system, colour or black and white camera, colour or black and white display, an access controller that is connected to fanout, an electric control lock that is electrically connected with controller, a schematic capture card software CD, a face picture of the present invention is discerned work attendance and gate control system optical disk of software.
Advantage of the present invention is as follows:
This face image identification entrance guard and attendance checking system recognition speed (are measured based on a PENTIUM400PC machine soon,) location head 50-300 millisecond, identification is judged≤1 second, low with other precision height (identification accuracy 〉=99%) system cost, there is good tolerance to require low to service conditions such as personage's background, light, attitudes to environment for use.
