Face recognition wing gate

I. Overview:

Face recognition is a biometric identification technology based on people's facial feature information. Its uniqueness and good characteristics of being difficult to copy provide the necessary prerequisites for identity identification. The face recognition pedestrian gate system It is to combine face recognition technology with the pedestrian passage system, and use face recognition as the key to open the pedestrian passage. It not only eliminates the trouble of forgetting to bring the key or card, but also because the face recognition pedestrian passage gate system does not require The door can be opened through any medium, which saves a lot of costs. For example, if there is a change of personnel, there is no need to replace the IC card, etc., only the face information needs to be re-registered; the face recognition pedestrian passage gate system is simple to operate, safe and convenient. It is smart and can be used both indoors and outdoors. It has always been more advantageous than IC cards that "recognize the card but not the person". In recent years, face recognition technology has been used in public security, customs, finance, military, airports, enterprises, etc. It has been widely used in many fields. Some experts further pointed out that the era of comprehensive application of face recognition has arrived, and it will become an important technology that facilitates people's daily life.

2. Product introduction and application scenarios:

200The megapixel dynamic offline portrait recognition camera adopts the internationally advanced neural network algorithm (CNN),It is a product formed after tens of millions of algorithm trainings. It integrates functions such as image collection, face detection, face tracking and face comparison. It not only has a high recognition rate but also a fast recognition speed. The offline dynamic portrait recognition machine does not require pedestrians. Designed with direct recognition, without computer control, pedestrians can also be recognized in motion, which greatly improves the ease of use of portrait recognition. The product can be used in any common access gate on the market (wing gate, swing gate, 3-roller gate, etc. ), access control and advertising doors, which can directly output gate opening signals and Wiegand signals; can be widely used in home entrances, community access control, school entrances and exits, gate passages, office buildings, subways, airports, high-speed rail and other scenarios.

At present, most entrances and exits in residential areas and factories use card verification. Problems often occur when there is no card. Face recognition technology is applied to the entrance and exit gate system, which is a safer identity verification method. Our company's face recognition The camera can be used in access control systems. It has the advantages of high recognition rate, fast recognition speed, and can adapt to high and low temperature harsh environments. After the face comparison is successful, the camera can directly output the switch signal to the gate, access control, advertising door and other equipment. Complete Door opening action.
