One. Analysis of the advantages of face recognition technology

Facial recognition technology is a kind of biometric recognition technology based on the facial feature information of people. The face recognition system integrates computer networks, artificial intelligence, machine recognition, video image processing, live detection, computer optics, physical sensors, statistical principles, and other professional technologies. This technology is currently widely used in public security systems and customs systems , Security system, banking system, etc.

two. Face recognition technology has four major advantages

1. Non-contact

The process of face verification does not require contact with devices or terminals, which is completely different from fingerprints and card punching methods. The experience is strong, the equipment should not be touched frequently, the stability is high, and the failure rate is low.

2. Naturalness

The first perception of human recognition of object characteristics is to pass back to the brain through the senses of the eyes. Face recognition technology is the process of using computer deep learning human senses to pass back to the brain. Therefore, face recognition is compared with other biometrics in the use and experience. It is more natural and does not require other object features, and there will be no problems such as loss or copying.

3. Fast recognition speed and high accuracy

Due to the development of computer technology, the speed of face recognition can be increased to 0.3 seconds/person-time under the comparison of the fixed sample library, and the behaviors that change the face from different angles, wearing glasses, make-up, etc. can also be corrected by adjusting the face recognition algorithm. To the data.

4. Face has become the preferred device for access control

The process of face recognition and comparison through a large number of areas does not require manual intervention, and is completely handed over.

The development and maturity of technology has made face recognition the most popular technology category and direction in the era of artificial intelligence. It has promoted the application of face recognition technology in all walks of life, replacing labor with machines, greatly improving and promoting efficiency in socialized behaviors. And safety.

three. Advantages of face recognition access control applications

Compared with other recognition methods, the use of face recognition access control has the following advantages:

1. No need to touch identification equipment

2. Natural recognition and control

3. Eliminate security vulnerabilities such as alternative opening, counterfeiting, and deliberate deception verification

4. Lost or forgotten identification card will no longer happen

six. Introduction to Face Recognition Channel Management System

There are many companies or departments in commercial buildings with different attributes, and the people working in them are also specific people. They are under the principle of confidentiality. People who do not belong to the office building are usually not allowed to enter. Facial recognition channel gates can be deployed at the main entrances or halls of the building, and single-channel, dual-channel or multi-channel can be deployed according to the actual site area and distance combination.

The face recognition channel gates can be combined into multiple channels, or set to one-way access mode. The authorization information on the face recognition gate terminal can be directly pushed to the terminal from the cloud through the network link. The form of deploying channel gates can eliminate the need to set up gates, and has a transparent sense of space, which guides personnel in and out of the standard, and avoids congestion.
