Description

Technical Field

[0001] The utility model relates to the technical field of face recognition, in particular to a face recognition and verification device based on graphic imaging. Background Art

[0002] Face recognition is a biometric technology that identifies people based on their facial features. It is a series of related technologies that use cameras or webcams to collect images or video streams containing faces, automatically detect and track faces in images, and then perform face recognition on the detected faces.

[0003] The existing face recognition and verification devices based on graphic imaging have the main problem of not being able to adjust the height of the recognition device during use, and thus cannot adapt to users of different heights. Users need to stand on tiptoe or bend over, which makes it inconvenient to use. Secondly, the existing face recognition and verification devices based on graphic imaging have a relatively complex comparison structure during use and do not have an alarm capability. When external personnel conduct verification, the staff cannot be notified in time, and the vigilance is insufficient. Utility Model Content

[0010] As a preferred technical solution of the utility model: a controller is fixedly installed on the back of the bracket, and the image storage and comparison module, power supply, alarm device, LED light group and camera are all electrically connected to the controller.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The face recognition verification device based on graphic imaging, through the coordinated use of the fastening bolt and the sliding rod, utilizes the threaded connection between the screw rod and the fastening bolt, and then when the fastening bolt is rotated, the fastening bolt slides inward on the outer edge of the screw rod, and then fits the outer edge of the bracket. At this time, the position of the outer frame can be fixed, and the setting of the friction plate 1 and the friction plate 2 is utilized, and then when the fastening bolt is tightened, the friction between the fastening bolt and the outer side of the slide rail is increased, thereby improving the stability of the outer frame.

[0013] 2. The face recognition verification device based on graphic imaging works through the coordinated use of an alarm device and an LED light group, and uses a controller to control the power supply to operate. The power supply is used to power the image storage and comparison module, the alarm device, the camera, and the LED light group. First, the correct image is stored in the image storage and comparison module using the camera, and then the face of the user is photographed using the camera. The result is then compared with the image stored in the image storage and comparison module. If the comparison result is correct, the user can pass. If the comparison is wrong, the result is transmitted to the alarm device, and the alarm device can then sound an alarm. The LED light group can be set to illuminate the face of the user at night when visibility is poor. BRIEF DESCRIPTION OF THE DRAWINGS
