Technical Field

[0001] The utility model relates to the technical field of face recognition, and in particular to an intelligent face recognition device for a park. Background Art

[0002] Face recognition is a biometric technology that identifies people based on their facial features. It uses a camera or camcorder to capture images or video streams containing faces, and automatically detects and tracks faces in the images, and then uses a series of related technologies to identify the detected faces. It is also commonly called portrait recognition or facial recognition.

[0003] In the prior art, the patent application number CN217784661U discloses a face recognition device for a smart park, including a frame and an adjustment mechanism, the adjustment mechanism is fixedly installed inside the frame, and the adjustment mechanism includes: a motor is fixedly installed at the bottom of the inner wall of the frame, a rotating rod is fixedly connected to the coupling of the motor, a threaded rod is fixedly installed on the top of the rotating rod, and a threaded hole is provided on the movable plate. By setting a motor, the threaded rod can be driven to rotate, and by setting a limit groove and a limit block, the movable plate can be limited, so that the movable plate can move up and down when the threaded rod rotates, thereby adjusting the height of the body of the face recognition device, and by setting an electric telescopic rod, the slider can be driven to slide on the inner wall of the slide groove, thereby driving the adjustment plate to rotate with the hinge point of the adjustment plate and the movable plate as the center of the circle, thereby achieving the purpose of adjusting the angle of the body of the face recognition device.

[0004] With respect to the above scheme, the following technical problems exist: most gates in the park require the use of an access control system, and in this case an intelligent face recognition device for the park is needed.
