Detailed Description of the Invention

[0016] The following further describes the present utility model in conjunction with the accompanying drawings.

[0017] As Figure 1 shown, the camera device for AI research and training designed in this application includes two parts: a robotic arm 1 and a camera 2. One end of the robotic arm 1 is connected to a fixed terminal, including but not limited to a training vehicle and an edge server, and the other end is connected to the camera 2. The robotic arm 1 includes a first connecting arm 11, a first motor 12, a second connecting arm 13, a second motor 14, a third connecting arm 15, a third motor 16, and a fixed hanging ear 17. Among them, the first motor 12 is respectively connected to the first connecting arm 11 and the second connecting arm 13. By controlling the first motor 12, the two robotic arms can be rotated circumferentially around the first motor to a certain angle. The inner and outer circles of the second motor 14 are respectively connected to the second connecting arm 13 and the third connecting arm 15. By controlling the second motor 14, the third connecting arm 15 can be rotated around its axis. The third motor 16 is a circumferential rotation motor, which is respectively connected to the third connecting arm 15 and the fixed hanging ear 17. By controlling the rotation of the third motor 16, the fixed hanging ear 17 can be rotated circumferentially. The lower end of the fixed hanging ear 17 is fixedly connected to the camera 2.

[0018] In this embodiment, an automatic control structure of the robotic arm suitable for video acquisition is given. Through the coordinated drive of three motors, precise adjustment of the camera position is achieved. Through the joint adjustment of multiple connecting arms, the camera can be fixed at any angle. Combining with the zoom function of the camera itself, the effects of automatic positioning and automatic zoom can be achieved, which is more convenient for users to perform video acquisition.

[0019] Based on the traditional camera device, this application not only integrates an electric adjustment robotic arm structure with multiple degrees of freedom, but also makes corresponding improvements on the existing camera module. It conducts an integrated optimization design for the heat dissipation problem of the camera itself, and optimizes the magnification and brightness adjustment functions of the camera to further simplify the operation. Specifically as Figures 2 - 3 shown.

[0020] The upper part of the housing of the camera 2 includes a connection seat 21, a cooling fan 22, and a cooling groove 23. Among them, several fixing holes are opened at the upper end of the connection seat 21, and a heat dissipation through hole is also provided in the middle. The connection seat 21 is connected to the fixed hanging ear 17 through the fixing holes, and a plurality of lateral heat dissipation holes are also opened at the lower end. The connection seat 21 is detachably connected to the lower circular cooling fan 22. An integrated cooling groove 23 is provided at the upper end of the housing of the camera 2, and a buckle is provided at the lower part of the cooling fan 22, which is fixed to the upper part of the cooling groove 23 by a clamping method.

[0021] The above design integrally integrates the heat dissipation slots of the camera into the camera housing, and at the same time sets the heat dissipation fan inside the connecting piece of the robotic arm module, which not only achieves the effect of sufficient heat dissipation, but also simplifies the design without the need to additionally install a heat dissipation module, facilitating user use. The detachable design of the connecting seat and the heat dissipation fan further improves the convenience and heat dissipation performance when using the camera module alone.

[0022] In addition, the camera 2 further includes an optical lens 24, an array microphone 25 for collecting audio information arranged on the side, and an IoT adjustment panel 27. The camera module provided in this application can not only realize the function of automatically collecting audio and video, but also integrates the IoT control function, and can change various environmental parameters in the current training scenario according to user needs. Cooperating with the remote server-side control system, it can realize a variety of IoT control functions including one-key class start, light switch, and curtain switch. For the situation where the position of the camera 2 needs to be manually adjusted, an adjustment handle 26 is also provided below the camera 2 in this application for the user to arbitrarily pull the camera 2 to the required position to meet the need for manually controlling the camera.

[0023] As Figure 3 shown, a mode switch 29 and an adjustment roller 210 for controlling the zoom magnification and brightness adjustment of the camera are also provided on the camera backplane 28. In order to simplify the button layout and operation difficulty in this application, the zoom magnification adjustment and brightness adjustment are respectively adjusted through the mode switch. In different modes, the adjustment roller 210 can be used to achieve fast and simple adjustment. While reducing the user's learning and usage costs, simplifying the buttons and reusing the roller adjustment mechanism can also provide the user with a continuous and smooth adjustment experience.

[0024] In the seminar training scenario, the imaging device provided in this application can be installed on edge control terminals, such as various types of terminals like training vehicles and podiums. When in use, the user sets the position of the camera through the edge control terminal, and the robotic arm realizes the precise positioning of the camera by adjusting the rotation angles and positions of 3 motors. After the camera positioning is completed, automatic zooming is performed, and audio and video are collected and transmitted at the optimal zoom magnification. When the user needs to manually position and shoot other scenes, they can arbitrarily pull it to a suitable position through the adjustment handle. After adjustment, they can also manually adjust the zoom magnification and brightness to the optimal state through the adjustment roller and then continue audio and video collection.

[0025] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
