Bio-electric gates refer to the traditional smart gates to increase fingerprint recognition, finger vein recognition, face recognition, palm vein recognition, iris recognition and other biological technologies, so that the diversification of the gates can be used to meet the needs of different occasions. . For example, the bio-electronic gate for airport security inspection can be used to display the ID and boarding pass to pass the self-service gate. Compared to the traditional boarding process, bio-electronic gates can significantly reduce waiting time.
Introduction of bioelectronic gate recognition method
First, fingerprint recognition
Fingerprint recognition is based on the texture of the human fingerprint, details and other information for the operation or identification by the operator. Thanks to modern electronic integrated manufacturing technology and fast and reliable algorithm research, it has begun to enter our daily life and become the current Bioinjection research is more in-depth, more widely used, and more mature technology
Second, finger vein recognition
Finger vein recognition is a kind of vein recognition. Firstly, the finger vein distribution map is obtained by the finger vein recognition instrument. The characteristic value is extracted from the finger vein distribution map according to the special comparison algorithm, and the finger vein is obtained by the CCD camera through the near-infrared light irradiation. The image stores the digital image of the finger vein in a computer system and stores the feature values.
Third, face recognition Face recognition is based on a person's facial features, an input face image or a video stream. First, it is judged whether or not there is a human face, and if there is a human face, the position and size of each face and the positional information of each main facial organ are further given. Based on this information, the identity features contained in each face are further extracted and compared with known faces to identify the identity of each face.
Fourth, palm vein recognition
Palm vein recognition is another mature technology in this field. When using the palm vein for identity authentication, it acquires the image features of the palm vein, which is the characteristic of the palm when it is alive. In this system, the non-living palm is not able to obtain the characteristics of the vein image, and thus cannot be identified, and thus cannot be faked.
Five, iris recognition
Iris recognition technology is now widely recognized. Iris recognition technology is more accurate, but sometimes there are recognition obstacles when the device performs retinal scanning.
The bio-electric gates need to be customized for the appearance and function of the intelligent gate channel according to the needs of different occasions.
