The face recognition attendance machine is a new type of storage attendance machine. It only needs to collect the face image of the employee and establish the file in advance. When the employee goes to work in the recognition area of ​​the face recognition attendance machine, the attendance machine will record quickly. Attendance status and save records.
Face recognition technology is based on human facial features, input facial images or video streams. First, it is judged whether or not there is a human face, and if there is a human face, the position and size of each face and the position information of each main facial organ are further given. Based on this information, the identity features contained in each face are further extracted and compared with known faces to identify the identity of each face.
1. Password registration: After the installation of each component of the system is completed, the personnel registration must be carried out before normal use. That is, password registration is performed for the person who is allowed to pass. Registered through the background management software, and the registration information will be stored in the controller so that the user can use the computer
2. Face registration: The first time you enter the registration password, the system is defined as face information registration. The first time the registered person enters the previously registered password, and then stands in front of the camera and stands at the camera. The system automatically scans the person's facial feature information and stores it in the controller. When the door lock is opened, the system completes the face registration. Then you can use it normally.
3. Entry control: firstly perform password verification outside the door. If the entered password is a valid password already registered on the controller, the system automatically starts the camera to confirm the face features. Confirm whether the face of the person to be entered is the face of the registered person corresponding to the entered password. After confirming that the faces meet, you can open the door and release it. If the face does not match, the system will return to the initial state and wait for the entered password.
4, go out control: go out to control: just press the exit button to release the door.
Going out is controlled: a camera and a PIN pad are connected to the controller in the door. Going out to control the same door control.
1. It is natural. The so-called naturalness means that the recognition method is the same as the biological characteristics used by humans (including other organisms) for individual identification. It is to observe and compare faces and confirm identity; and to have natural identification. There are speech recognition and body shape recognition, and fingerprint recognition and iris recognition are not natural because humans or other organisms cannot distinguish individuals through such biometrics.
2, is non-mandatory, the recognized face image information can be actively acquired without being perceived by the measured individual, face recognition is to obtain facial image information by using visible light, and different from fingerprint recognition or iris recognition needs to be collected by electronic pressure sensor Fingerprints, or the use of infrared to collect iris images, these special collection methods are easily noticeable, and can be deceived by camouflage.
3. It is non-contact. Compared with other biometric technologies, face recognition is non-contact, users do not need to directly contact with equipment, and at the same time can meet the sorting, judgment and identification of multiple faces in actual application scenarios. .
4, low-cost coverage alternative storm design, low selling price, to achieve the application of the latest biometric technology. Get up and brush your teeth, brush your face at work, pick up your face and replace the fingerprint storm! 3. Non-contact health and hygiene are completely non-contact, avoiding hundreds of people who have been using a fingerprint collection head for many years, which is neither hygienic nor easy to wear fingerprint collection head.
5, U disk download network communication According to the customer's actual network conditions and usage habits, U disk download, network communication, any one of them, can achieve the device user, record upload and download.
6, fingerprint attendance machine replacement product face attendance is the development trend of the market, to solve the problem of unsanitary fingerprint recognition machine, low recognition rate, and the lower price of this product is closer to the consumption habits of SMEs, the price is more Close to the grain attendance machine.
1. The recognition speed of face recognition attendance machine is slower than that of fingerprint attendance machine. Not suitable for relatively large companies for attendance.
2. The price of the face recognition attendance machine is higher than the price of the fingerprint attendance machine. After years of development, the purchase cost of fingerprint attendance machines is getting lower and lower, and the technology is becoming more and more mature.
3. The current development of face recognition technology is still fully mature, and there is no application risk in technology.
Therefore, to answer questions such as face recognition attendance machine, face recognition attendance machine and fingerprint attendance machine which are easy to use and other related issues, it is necessary to consider the above factors in consideration, or use fingerprint attendance machine is more appropriate. Or, some buyers feel that fingerprint attendance machines have the phenomenon of punching cards, but this is a rare behavior. If you really want to prevent this from happening, you can use another face recognition attendance machine with a preventive generation punch card.
