On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0043] According to a first aspect of the present invention, a whiteboard recording instrument 100 is provided.

[0044] Figure 1-Figure 5 The schematic diagram of the structure of the whiteboard recording instrument 100 in the embodiment of the present invention is shown.

[0045] like Figure 1-Figure 5 As shown, the whiteboard recording instrument 100 in the present invention includes an instrument body 1, wherein the instrument body 1 includes a supporting structure 11 and a mounting shell 12, one end of the supporting structure 11 is connected to the mounting shell 12, and the end of the supporting structure 11 opposite to the mounting shell 12 is used for installation and fixing, so as to install the whiteboard recording instrument 100 at a desired position; the mounting shell 12 has an accommodating space inside, and a first window 121 and a second window 122 connected to the accommodating space are opened on the side wall of the mounting shell 12.

[0046] The whiteboard recording instrument 100 also includes a first camera module 2 and a second camera module 3, wherein the first camera module 2 and the second camera module 3 are both arranged in the accommodating space of the mounting shell 12, and the first camera module 2 is arranged corresponding to the first window 121, and the observation area of ​​the first camera module 2 at least covers the entire area of ​​the whiteboard 300; the second camera module 3 is arranged corresponding to the second window 122, and the second camera module 3 rotates relative to the mounting shell 12 so that its observation area covers the scene area outside the whiteboard 300.

[0047] In the embodiment of the present invention, the whiteboard recording instrument 100 is provided with a first camera module 2 and a second camera module 3 to realize photographing the meeting scene and participants while photographing the whiteboard 300, thereby eliminating the need for additional equipment and reducing equipment and conference layout costs.

[0048] It is worth mentioning that the scene area in the present invention mainly refers to the meeting scene and participants.

[0049] like Figure 3 and Figure 5 As shown, the mounting shell 12 includes a top plate, a bottom plate, and a side plate connected between the top plate and the bottom plate, a first window 121 is opened on the bottom plate, and a second window 122 is opened on the top plate and extends downward to the side plate.

[0050] like Figure 1 As shown, the instrument body 1 further includes a bottom shell 13, which is arranged at an end of the support structure 11 opposite to the mounting shell, and may also be referred to as a bottom end.

[0051] In the embodiment of the present invention, the support structure 11 includes an outer shell 111 and a support plate 112 , and is a hollow strip structure formed by splicing the support plate 112 and the outer shell 111 .

[0052] like Figure 3 and Figure 5 As shown, the first camera module 2 includes a first camera 21 and a bracket 22, wherein the first camera 21 is suspended on the bracket 22 and is arranged corresponding to the first window 121 for photographing the whiteboard 300; an end of the bracket 22 away from the first camera 21 is connected to the supporting structure 11, so as to firmly install the first camera module 2.

[0053] like Figure 3 As shown, the first camera module 2 also includes a protection cover 23 for protecting the first camera 21 .

[0054] In the embodiment of the present invention, the bracket 22 is in a plate shape, one end of which is provided with a mounting hole for suspending the first camera 21 ; and the other end is used for connecting to the supporting structure 11 .

[0055] The end of the bracket 22 opposite to the first camera 21 is inserted into the interior of the support structure 11 which is a hollow strip structure.

[0056] In an embodiment of the present invention, the first camera module 2 further includes a board 24 that drives and controls the first camera 21 .

[0057] like Figure 3 and Figure 5As shown, the second camera module 3 includes a second camera 31, a movable component 32 and a driving mechanism 33, wherein the movable component 32 is arranged at the second window 122, the movable component 32 has an installation cavity inside, an opening 321 communicating with the installation cavity is opened on a side wall of the movable component 32, the second camera 31 is placed in the installation cavity, and is arranged corresponding to the opening 321 of the installation cavity;

[0058] The driving mechanism 33 is fixedly arranged, and the movable component 32 is in transmission cooperation with the driving mechanism 33. Under the driving action, the movable component 32 rotates relative to the second window 122 to drive the second camera 31 to move relative to the second window 122, so that the observation area of ​​the second camera module 3 covers the scene area outside the whiteboard 300.

[0059] In an embodiment of the present invention, the second camera module 3 can be flexibly rotated to adjust the angle thanks to the transmission cooperation between the movable component 32 and the driving mechanism 33, wherein there are three ways of driving the movable component 32 to rotate, that is, the movable component 32 has three rotation adjustment modes, corresponding to the three adjustment modes of the second camera module 3, so that the observation area of ​​the second camera module 3 covers the scene area outside the whiteboard 300, so that the whiteboard recording instrument 100 can take into account the shooting of the scene and the participants while shooting the whiteboard 300.

[0060] Figure 8 and Fig. 9 The whiteboard recording instrument 100 is shown in the figure for adjusting the rotation in different usage scenarios. Figure 8 The rotation adjustment method of the whiteboard recording instrument 100 when the participants are seated in the scene shown, Fig. 9 The figure shows the rotation adjustment method of the whiteboard recording instrument 100 when the participants are standing in the scene. The whiteboard recording instrument 100 can be selectively adjusted according to the actual situation. For example, an algorithm electric adjustment mode can be adopted to control the rotation of the motor according to the position of the head to adjust the rotation of the second camera module 3 to obtain the best shooting effect.

[0061] As an embodiment of the present invention, the angle adjustment of the second camera module 3 is realized by manual adjustment, which can be understood as manually moving the second camera module 3 to rotate it relative to the second window 122. Specifically, manually moving the driving pattern 323 can realize the rotation of the movable part 32 relative to the second window 122, thereby driving the second camera 31 to move relative to the second window 122, and then realizing that the observation area of ​​the second camera module 3 covers the scene area outside the whiteboard 300.

[0062] like Figure 3 and Figure 5As shown, the side of the movable component 32 facing the second window 122 is arc-shaped, and a driving pattern 323 is provided on the side. The movable component 32 can be rotated and adjusted by manually turning the driving pattern 323. The operation is very convenient, and the addition of the manual turning adjustment mode makes the angle adjustment of the second camera module 3 more selective, adapted to local conditions, and has a wider range of applications.

[0063] As another embodiment of the present invention, the angle adjustment of the second camera module 3 is realized by electric adjustment, which can be understood as using electric control to rotate the second camera module 3 relative to the second window 122. Among them, the electric adjustment can be specifically divided into remote control electric adjustment and algorithm active electric adjustment, which is not limited to a single electric control adjustment method and is more diversified and intelligent.

[0064] Specifically, the driving mechanism 33 utilizes the motor therein to cooperate with the transmission member 322 in the movable component 32, and then utilizes the control system to control the rotation of the motor, thereby driving the movable component 32 as a whole to rotate relative to the second window 122, thereby driving the second camera 31 to move relative to the second window 122, thereby achieving the observation area of ​​the second camera module 3 covering the scene area outside the whiteboard 300.

[0065] Among them, on the one hand, the control system can receive adjustment signals, such as using a remote control to send adjustment signals to the control system to adjust and control the rotation of the second camera module 3; on the other hand, an imaging algorithm can be designed and formed in the control system, and the control system can control the rotation of the motor according to the position of the head to adjust and control the rotation of the second camera module 3.

[0066] Of course, remote control electric adjustment and algorithm active electric adjustment can be used as two independent modes for autonomous selection and switching. For example, in a non-static meeting where some participants need to move around, the algorithm electric mode can be activated to autonomously adjust and control the rotation of the second camera module 3 according to the position of the head to obtain the best shooting effect. Figure 3 and Figure 5 As shown, a transmission member 322 is provided on the side wall of the movable component 32 adjacent to the opening 321 , and the transmission member 322 cooperates with the driving mechanism 33 in transmission, so that the movable component 32 can rotate relative to the second window 122 .

[0067] In an embodiment of the present invention, the driving mechanism 33 includes a motor and a control system connected to the motor control. The output shaft end of the motor is in transmission cooperation with the transmission member 322. The control system can receive an adjustment signal and control the rotation of the motor.

[0068] As an embodiment of the present invention, the transmission member 322 is a gear structure, and the driving mechanism 33 is provided with a toothed member that meshes with the gear structure for transmission.

[0069] For example, a gear member may be provided on the output shaft of the motor to achieve meshing cooperation with the transmission member 322 .

[0070] Of course, the output shaft end of the motor can also be connected to the transmission member 322 by belt transmission, so there can be many specific transmission connection methods, which are not specifically limited.

[0071] In an embodiment of the present invention, a remote controller may be used to send an adjustment signal to a control system to adjust and control the rotation of the second camera module 3 to achieve an up and down angle adjustment thereof.

[0072] In an embodiment of the present invention, an imaging algorithm is configured in the control system. Using the imaging algorithm, based on the setting of centering the human head in the picture, the motor is controlled to rotate according to the position of the human head to adjust the rotation of the second camera module 3 to achieve its up and down angle adjustment.

[0073] like Figure 3 and Figure 5 As shown, the second camera module 3 further includes a protective cover 34 for protecting the second camera 31 , wherein the protective cover 34 is disposed at the opening 321 of the movable component 32 , and a through hole for exposing the second camera 31 is formed on the protective cover 34 .

[0074] A second aspect of the present invention provides a whiteboard device, which includes the whiteboard recording instrument 100 provided by the first aspect of the present invention.

[0075] in, Figure 6 The structure of the whiteboard device is shown. Figure 7 The following diagram shows the usage scenario of the whiteboard device.

[0076] like Figure 6-Figure 7 As shown, the whiteboard device in the present invention includes a whiteboard 300, a display 200 and a whiteboard recording instrument 100; wherein,

[0077] The whiteboard recording instrument 100 is fixed above the whiteboard 300 via a support structure 11, for example, it can be fixed on a wall or on the top of the whiteboard 300;

[0078] The display 200 is controlled and connected with the first camera module 2 and the second camera module 3. The display 200 can display remote content and can be connected to the first camera module 2 and the second camera module 3 wirelessly or by wire.
