Description

Technical Field

[0001] The utility model relates to the technical field of cameras, in particular to an intelligent cloud-table camera. 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, automatically detects faces in images, and then performs facial recognition on the detected faces. It is also commonly called portrait recognition or facial recognition.

[0003] Currently, binocular camera modules used for face recognition are usually used in gates, ATM boxes, or other equipment. When performing face recognition, due to the large difference in people's heights, and the limitations of the camera installation position and camera imaging angle, people need to adjust the position of the face in the camera image by themselves to align the face with the center of the image to achieve the best face recognition and liveness detection effect, but this operation is very inconvenient.

[0004] The camera lens of the existing intelligent pan-tilt camera is fixed to the camera body and cannot be rotated and adjusted. Aligning the center of the face with the center of the graphic is completely done by manual operation. Utility Model Content

A rotating shaft 11 rotatably connected to an external fixture is provided at one end of the housing 1, and a rotating device 2 fixedly connected to an external fixture is provided at the other end of the housing 1.

[0043] Specifically, Figure 1-3 As shown, the rotating device 2 includes a rotating motor 21 fixedly installed in the front shell 12, and a fixed block 22 fixedly installed on an external fixed object. The rotating motor 21 is provided with a motor output shaft, and the motor output shaft loosely passes through the shell 1 and is fixedly connected with the fixed block 22, or the motor output shaft is rotatably connected with the shell 1. The rotating device 2 also includes an angle limit block 23, and a limit protrusion is provided on the angle limit block 23. The angle limit block 23 is placed in the shell 1 and fixedly installed on the motor output shaft. The limit protrusion is used to limit the rotation angle of the rotating device 2, and the rotation angle of the rotating device 2 is ±30 degrees. The rotating motor 21 adopts a servo motor or a stepping motor.

[0044] Specifically, Figure 1-3As shown, the first lens 3 is an acrylic lens, and the second lens 5 is a filter lens. The infrared lamp 4 is fixedly installed in the front shell 12, and the infrared lamp 4 uses an 850 infrared lamp board. The second lens 5 is placed outside the infrared lamp 4 and fixedly installed on the front shell 12. The first lens 3 is placed outside the second lens 5 and fixedly installed on the front shell 12.

[0045] Specifically, Figure 1-3 As shown, the lens group 6 includes two non-distortion lenses 61, one wide-angle lens 62 and one face tracking lens 63. The non-distortion lenses 61, one wide-angle lens 62 and one face tracking lens 63 are fixedly mounted on a PCB mainboard 7 respectively. The PCB mainboard 7 is fixedly mounted in the front shell 12.

[0046] The utility model also includes a control system, which is used to receive signals from two distortion-free lenses 61 , one wide-angle lens 62 and a face tracking lens 63 and control the operation of the infrared lamp 4 and the rotating motor 21 .

[0047] Installation of the utility model: fix the infrared lamp 4 in the front shell 12 by screws, install a face tracking lens 63 in the front shell 12, and fix it by the buckle of the front shell 12.

[0048] Working principle: When a face is detected, the two distortion-free lenses 61, the wide-angle lens 62 and the face tracking lens 63 transmit a signal to the control system. The control system sends a signal to the rotating motor 21 according to the specific situation of whether the center of the face is aligned with the center of the graphic. The rotating motor 21 receives the signal from the control system and drives the output shaft of the rotating motor 21 to rotate a certain angle. Because the motor output shaft of the rotating motor 21 is fixed to the fixed block 22, and the rotating motor 21 is fixed to the front shell 12, the rotating motor 21 rotates a certain angle with the front shell 12, the rear shell 13, the lens group 6, the infrared lamp 4, the first lens 3, the second lens 5, and the PCB main board 7.
