Speed ​​gate

Speed-pass gates are mainly used for pedestrian passage management; they have the characteristics of quick opening, safety, and convenience, and are ideal management and grooming equipment for pedestrians with high frequency access passages. The use of face recognition speed-pass door wing gate technology for speed-pass doors is a technological innovation. For users, it not only simplifies management, but also improves safety. Let's take a look at what are the characteristics of dynamic face recognition.

The quick-pass door has a fast response speed, and the quick-pass can be adjusted every second of the opening time. Generally, the quick-pass is already very fast, which is more than twice that of the ordinary swing gate, which can facilitate pedestrians to pass quickly. This is the quick-pass door. One of the advantages is that it also has anti-collision. The ordinary swing gate is not anti-collision at all. The anti-collision swing arm can be anti-collision, but it cannot be reset. It needs to be reset manually. This is not very convenient. The quick-pass door has anti-collision and automatic reset. , For example, when the sluice gate suddenly encounters an external force, the swing arm will shift in the direction of the acting force to eliminate the external force. The swing arm can be automatically reset, and it is easy. If someone breaks into the brake, the swing arm locks automatically and the machine emits an alarm sound. According to the alarm sound, the officer found the person who broke the gate.

According to the facial feature inspection skills: after selecting colors, generalization, texture, structure or histogram features, etc., face inspection.

Face matching skills based on template matching: Get face templates from the database, and then adopt a certain template matching strategy to match the captured face pictures with those obtained from the template library, and determine the person by the level of correlation and the size of the matched template Face size and location information.

Face-checking skills based on calculation: After collecting a lot of pictures about “faces” and “non-faces”, a positive and negative sample library of faces is selected, and the calculation method is used to strengthen the training system, and then complete the face and non-person Check and classify the face patterns. Domestic type This famous face recognition passenger flow calculation has Yaliang stores.

Face recognition features of Speedgate

Geometrical features: The distance and ratio between face points are used as features. The recognition speed is fast, the memory request is relatively small, and the sensitivity to light decreases.

According to the model features: according to the different probabilities of different features, the features of the face drawing are obtained.

According to the calculation characteristics: treat the face picture as a random vector, and use the calculation method to distinguish the different face characteristic patterns, which are more typical with characteristic faces, independent component analysis, singular value decomposition, etc.

According to the characteristics of neural network: many neural units are used to associatively store and recall the features of face drawings, and the accurate recognition of face drawings is completed according to the probability of different neural unit conditions.

The speed gate has a voice prompt, and the gate will pass normally, there will be a voice prompt, a sense of intimacy, you can change the prompt mode. In fire protection mode, the sluice gate automatically receives the fire mode signal, and the sluice gate automatically enters the fire safari mode. It is suitable for emergency evacuation. The gate will not be closed at will. The power gate will automatically open. It meets the requirements of the fire protection function. , The gate is connected to the computer, can be operated remotely, set remotely, and can be operated remotely with the network, compatible with Android and Apple systems, saving trouble and worry.
