Today, with the continuous development of artificial intelligence, many things are becoming intelligent. Taking our access control as an example, after iterations of physical keys, door cards, passwords, and fingerprints, it has entered the era of face recognition. Face recognition access control machines have also been popularized in communities, hospitals, schools, office buildings, factories and other places. It only takes one or two seconds of recognition, and the access control system will operate according to the comparison results. Especially during the epidemic, the face recognition access control system has played a significant role in protecting everyone's work and life with its non-contact advantages.
So how is the face recognition function of the access control system realized? We can understand several key elements of access control:
1. Hardware installation. According to the size of the community entrance and the scale of the flow of people, different numbers of access control gates are installed, and a face recognition access control system is installed on the gates, which is the hardware basis for access control face recognition.
2. System configuration. Connect the connection lines of each data port, configure the parameters and network on the face recognition access control machine, and keep the system in the open state.
3. Face registration
Usually, it can be done in two ways: on-site entry and remote entry (access link and QR code for online entry). Like face recognition on a mobile phone, the face is collected and entered. For online entry, the entry result needs to be reviewed by the system administrator.
4. Face comparison
After the face is successfully entered, the system retains the photo of the face as a comparison model. Through the face comparison API interface connected to the system, when there is a real-time face for verification, the camera will sample and generate biometric data. By comparing with the photos in the stored face database, it can quickly confirm whether it is the person, and automatically choose whether to grant access.
The above-mentioned access control face recognition function is just a basic face comparison, which can meet most face recognition scenarios. If there are higher requirements for the security environment, it can be deployed with the live detection interface and the witness comparison interface.
