company news about How is the face recognition function of the access control system realized?

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 the face recognition on the mobile phone, the face is collected and entered. For online entry, you also need to pass The system administrator reviews the input results.

4. Face comparison After the face is successfully entered, the system saves the face photo 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, and pass and save the face Compare the photos in the library, quickly confirm whether it is the person, and automatically choose whether to grant access.

The above access control face recognition function is only a basic face comparison, which can meet most face recognition scenarios. If there are higher requirements for the security environment, it can be carried out with live detection and witness comparison. The former is to solve the problem of people using The problem of photo mask cheating and deceiving the system, the latter is to compare the photo of the ID card with the face of the public security database to ensure that the witnesses are consistent.
