However, existing crowd detection devices cannot take photos of the same field of view in multiple dimensions, cannot accurately count the flow of people, and have the defect of low accuracy. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the utility model provides a crowd detection camera based on video AI, which has the advantages of simple operation, easy installation, wide shooting angles, high statistical accuracy, etc., and solves the above-mentioned technical problems.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a video AI-based human flow detection camera, comprising a base plate, a fixing seat installed on the front end of the upper surface of the base plate, a bearing installed on the upper surface of the fixing seat, a gear plate installed on the upper surface of the bearing, a chassis installed on the upper surface of the gear plate, a camera installed on the upper surface of the chassis, a lens protection sheet installed on the front end of the camera, a servo motor installed on the rear end of the upper surface of the base plate, a protective cover installed on the outside of the servo motor, a rotating rod installed on the output shaft of the servo motor, a transmission gear installed on the end of the rotating rod, a protective plate installed on the rear end of the base plate, and a back plate installed on the back of the protective plate.

[0008] Preferably, the gear plate is meshed with the transmission gear.

[0009] Through the above technical solution, high-precision control of the camera angle can be achieved through the combination of the servo motor, the transmission gear and the gear plate. The servo motor has a high-precision position feedback system, which can accurately control the rotation angle of the output shaft, thereby achieving precise camera positioning and angle adjustment, and the engagement of the transmission gear makes the rotation of the camera smoother, reducing the camera shaking caused by vibration or external force interference, thereby improving the stability and clarity of the captured image.

[0010] Preferably, the protection plate and the back plate are rotatably connected via an installation pin.

[0011] Through the above technical solution, the pin-shaft rotation connection is installed so that the protection plate and the back plate can rotate relative to each other, thereby realizing the adjustment of the upper and lower angles. The shooting angle and field of view of the camera can be freely adjusted as needed to adapt to different monitoring needs. It can also provide a relatively stable connection to maintain the stability of the set angle. Even in the case of vibration or external force interference, the angle of the camera can remain relatively stable, ensuring the clarity and stability of the captured image.

[0012] Preferably, a receiving antenna is installed on the inner wall of the top of the protection plate, and the receiving antenna is connected to the camera by setting a connecting line.

[0013] Through the above technical solution, installing the receiving antenna on the top of the protective plate can improve the signal reception effect. The protective plate can play a certain shielding role, reduce interference signals from other directions, thereby enhancing the receiving antenna's ability to receive the target signal. The receiving antenna is connected to the camera through a connecting line. The connecting line can provide good signal transmission quality, reduce signal attenuation and interference, ensure the stability of the received signal quality, and improve the camera's working efficiency and the quality of the video image.

[0014] Preferably, a plurality of threaded holes are provided on the surface of the back plate, and the plurality of threaded holes are respectively provided at four corners of the back plate.

[0015] Through the above technical solution, the back panel can be easily installed and fixed by opening threaded holes on the four corners of the back panel. The user can use bolts or screws to firmly fix the back panel in the desired position to ensure the stable connection between the back panel and other equipment or structures. Setting the threaded holes on the four corners of the back panel can provide more stable installation and support, which can make the back panel evenly stressed during the installation process, disperse the bearing load, and increase the stability and reliability of the installation.

[0016] Preferably, a signal receiver is installed on the back of the camera.

[0017] Through the above technical solution, by installing a signal receiver on the back of the camera, remote control of the camera can be achieved. The user can use other devices, such as a remote control, mobile phone or computer, to send signals to the signal receiver to control various functions of the camera, such as shooting, adjusting angles, zooming, etc. This remote control method is convenient and fast, and is particularly suitable for scenes that require flexible control of the camera. Remote control through a signal receiver can reduce the complexity of wiring. Compared with directly connecting the device to the camera by wire, using a signal receiver can avoid long-distance wired transmission and reduce the trouble and cost during the wiring process.

[0018] Compared with the prior art, the utility model provides a human flow detection camera based on video AI, which has the following beneficial effects:

[0019] 1. The utility model can achieve high-precision control of the camera angle through the combination of a servo motor, a transmission gear and a gear plate.

The meshing of the transmission gear makes the rotation of the camera more stable, reduces the camera shaking caused by vibration or external force interference, and thus improves the stability and clarity of the captured image.

[0020] 2. The utility model can realize remote control of the camera by installing a signal receiver on the back of the camera. The user can use other devices, such as a remote control, a mobile phone or a computer, to send signals to the signal receiver to control various functions of the camera, such as shooting, adjusting angles, zooming, etc. This remote control method is convenient and fast, and is particularly suitable for scenes that require flexible control of the camera. Moreover, remote control through the signal receiver can reduce the complexity of wiring.
