The large-scale application of fingerprint identification products in attendance partly solved the problem of punching in. More than 5% people are born with shallow fingerprints, which leads to slow recognition speed, long queues during peak hours, and even some people can't recognize fingerprints. Fingerprint attendance products are difficult to identify when the weather is dry or the seasons change. Because it must be contacted, it provides a convenient carrier for the spread of bacteria and poses a certain threat to the health of employees.
With the continuous progress and development of society, there are more and more disadvantages of fingerprint attendance machine, which makes more and more enterprises no longer use fingerprint attendance machine for attendance punching.
During this epidemic, non-contact face recognition temperature measurement came into our lives, which also made us really feel the security and convenience brought by intelligent technology. In such a big environment, many enterprises began to use face recognition attendance.
Second, what is face recognition
Face recognition technology is based on human facial features, which processes the input face image or video stream, further extracts the identity features of each face according to the position and size of each face and the location information of the main facial organs, and compares them with known faces. A series of related technologies of face recognition system, including face image acquisition, face positioning, face recognition preprocessing, identity confirmation and identity search, are used to confirm the identity of a specific person.
Third, face recognition attendance introduction
Face recognition attendance can be used not only as an attendance system, but also as an access control system. It consists of front-end face recognition equipment, access control attendance management software and front-end visitor registration terminal. Through the management software to enter the face white list, set the access time period and attendance rules, the problem of quick access for internal personnel to brush their faces is realized, and the problem of staff punching and attendance is solved. At the same time, by quickly registering the information of visitors and recording the visiting records in detail, the scientific management of foreign personnel is realized, the security needs are met, and the workload of managers is reduced. The advanced face recognition algorithm is adopted in the system, and the high-speed chip is used as the hardware platform for the recognition algorithm. Through the identity information collection of the entrance and exit and the real-time face capture recognition, the identity verification of the people entering and leaving the entrance is realized.
IV. Advantages and Characteristics
1. non-contact, users don't need to touch the equipment directly;
2. The user's acceptance is high, and he agrees with nature without personnel operation;
3. It can be traced afterwards, and photos of identification and comparison can be kept;
4. It is not mandatory, and the recognized face image information can be obtained actively;
5. Fast and efficient, and normal walking speed can also be recognized.
