System survey (face recognition gateway)

Face recognition is a biological recognition technology based on human facial feature information for identification. Its uniqueness and good characteristics that are not easily replicated provide the necessary preconditions for identity authentication. The face recognition system combines the face recognition technology with the access control system, and recognizes the face as the key to the access control. It not only eliminates the trouble of forgetting to bring the key or card, but also saves a lot of cost because the face recognition access control system does not need any media to open the door, such as personnel changes, no need to replace the door lock, key, IC card, etc., only need to re-register your face. In addition, the face recognition access control system can also set access rights according to the entry and exit personnel, including different time periods, different access points, and the like.

With the rapid development of social economy, the comfort and safety of the living environment has become the first choice for people to live. The important role played by the access control system in a safe living environment has received more and more attention. At present, the domestic access control system is mainly based on card equipment, fingerprint equipment or password equipment. These recognition methods require people to operate at close distances, which are extremely inconvenient when the user’s hands are occupied, and also cause possibility of card or password missing, forgetting, copying, theft and problem of high cost. While fingerprint recognition, the fingerprint set on the internet has cracked the “password”, which makes people feel panic and uneasy.

How to make the access control system truly realize security, intelligence, and convenience has become the most anticipated thing for all citizens. At this time, the advent of the face recognition access control system has truly solved the management of residents entering and leaving and visitors. Community and building anti-theft form effective high security management.

Advantage analysis (face recognition gateway)

In the community and enterprise access control applications, the face recognition access control system is more advantageous than the “cards that do not recognize people” because of its simple operation, security, convenience, and intelligence, and the features that can be used indoors or outdoors. In recent years, face recognition technology has been widely used in public security, ports, universities, airports, enterprises, service industries, and other fields. The era of full application of face recognition has arrived, and he will become an important technology to facilitate people’s daily lives.

Function introduction (face recognition gateway)

1.Human face database: realize the construction of the control personnel, can be logical classification and comparison policy setting according to the personnel attributes.

2.Real-time capture: The face capture camera actively reports the detected face, and the system performs feature code extraction and storage, picture storage and portrait real-time display on the face.

3.Real-time warning: according to comparison strategy, the collected face and control list are compared in real time, and once the threshold is reached, the real-time alarm is generated. It can carry out high-risk personnel control reminders, frequent analysis alarms, regional collision analysis alarms, and alarm video linkage.

4.Face query: Unique distributed memory analysis engine to achieve billion-level search. Support matching face images with a distance of not less than 8 pixels.

5.Searching face: Query the qualified face in the face database of the corresponding option according to the uploader image and the search condition (including the blacklist library and the capture library) .

6.The blacklist deploy and control: Add to the blacklist database for those who need to be controlled. At the same time, the blacklist library can be used to arm the face according to the information such as the capture machine, time, location and similarity alarm threshold. Support the bottom library for 100,000 face database blacklist real-time alarm response speed is less than 1 second. Blacklist alarm hit accuracy is not less than 99%.

7.Accurate identification: Scalable design, support ways of 1:1, 1: N, N: N. Face alignment speed: 1: N > 16,000,000 times/second, The face detection rate of the person’s picture is not less than 99%.

8.The dynamic portrait library: Store and manage captured portrait pictures, life photos, features, attributes, realize distributed storage and distributed query of portrait model database, provide parallel query service, support billion-level portrait library application.

9.Face gender and age recognition: Support the recognition of face gender and age, face detection rate is not less than 95%, face gender recognition accuracy is not less than 99%.
