Detailed Description

The application is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are for purposes of illustration and not of limitation. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present application are shown in the drawings.

It should be noted that the present disclosure is not limited to all the alternative embodiments, and those skilled in the art who review this disclosure will recognize that any combination of the features may be used to construct the alternative embodiments as long as the features are not mutually inconsistent.

The camera adjusting method and the image collecting method in the embodiment of the application can be applied to an interactive panel, and the interactive panel applied by the scheme can be integrated equipment for controlling the content displayed on a display screen and realizing man-machine interaction operation by a touch technology, and integrates one or more functions of a projector, an electronic whiteboard, a curtain, sound equipment, a television, a video conference terminal and the like. Of course, the interactive tablet does not include a definition of the surface features of the display surface, e.g., the surface features of the interactive tablet may be planar, curved, or a splice of multiple planes, etc.

Typically, the interactive tablet is equipped with at least one operating system, wherein the operating system includes, but is not limited to, an android system, a Linux system, a Windows system, and a wintersweet system, which are used to control and coordinate the interactive tablet and external devices, so that various independent hardware in the interactive tablet can work as a stable whole. As shown in fig. 4, the interactive tablet 10 includes at least one display screen 20. For example, the interactive tablet 10 is configured with a touch-enabled display screen 20, i.e., a touch-sensitive display screen. The touch sensitive display may be an infrared display, a capacitive display, a resistive display, an electromagnetic display, or a pressure sensitive display, among others. On the display screen 20 having the touch function, a user may implement a touch operation by touching the display screen 20 with a finger or a writing pen, and accordingly, the interactive tablet 10 detects a touch position and responds according to the touch position to implement the touch function. When the touch sensing modules adopted on the display screen 20 with the touch function are different, the original touch sensing signals collected by the touch sensing modules are different, and the converted touch signals are not identical. In order to simplify the following description, the display content in the interactive tablet 10 is shown and described only by using the display screen 20 as a display area, and the area outside the display screen 20 in the interactive tablet 10 is not repeatedly displayed. In the interactive tablet 10, in order to implement a quick operation of a common function without exiting from a current page, sidebars are typically disposed on two sides of the display screen 20, where a plurality of function controls are displayed, for example, a camera control 201 for starting a camera, a writing control for quickly starting writing, and the like.

For the infrared display screen, the touch sensing module is an infrared touch frame, the touch signals acquired by the touch sensing module can comprise signals representing infrared blocking, the touch signals obtained through conversion can comprise position touch signals, and the position touch signals can comprise X coordinates and Y coordinates of touch positions. For the capacitive display screen, the touch sensing module is a capacitive touch pad, the touch signals collected by the touch sensing module can comprise currents flowing through electrodes of the touch screen, the touch signals obtained through conversion can comprise position touch signals, and the position touch signals can comprise X coordinates and Y coordinates of touch positions. For the resistive display screen, the touch sensing module is a resistive touch pad, the touch sensing signals collected by the touch sensing module can comprise voltages of touch positions, the touch signals obtained through conversion can comprise position touch signals, and the position touch signals can comprise X coordinates and Y coordinates of the touch positions. For the electromagnetic display screen, the touch sensing module is an electromagnetic plate, the acquired touch sensing signals can comprise the variation of magnetic flux and the frequency of the received electromagnetic signals, the touch signals obtained through conversion can comprise position touch signals corresponding to the variation of the magnetic flux and pressure sensing signals corresponding to the frequency, the position touch signals can comprise X coordinates and Y coordinates of touch positions, and the pressure sensing signals can comprise pressure values. For the pressure-sensitive display screen, the touch sensing module is a pressure sensor, the touch sensing signals acquired by the pressure sensor can comprise pressure signals, the touch signals obtained through conversion can comprise position touch signals, and the position touch signals can comprise X coordinates and Y coordinates of touch positions.

The interaction panel based on the touch-sensitive display screen can be used for acquiring the field pictures in real time to carry out picture sharing when being used in a multi-person communication scene such as a video conference, so that communication participants have better communication experience, and the information transmission effect in the multi-person communication process is improved. In the actual process of acquiring a field picture, a camera in an interactive tablet can only acquire image data and share pictures by default parameters, and the pictures shared in the mode are not usually the pictures which are required to be transmitted most on site. For example, in a conference room, the interactive flat board is installed on a side wall surface, the camera performs image data acquisition and image sharing according to default parameters, the background of the image may be a majority of conference rooms, the foreground is communication participants in the conference room, at this time, the communication participants occupy only a small proportion in the image, the image sharing is insufficient for the remote communication participants to see on-site emphasis, and therefore, the camera needs to be adjusted, so that the image data acquisition and image sharing of a heavy point region in the conference room are realized.

Referring to fig. 2 and3, an existing interaction process for adjusting a camera is presented. As shown in fig. 2, the camera position setting interface includes a setting window 251, a zoom control 253 and a movement control 254, first, a preview shooting picture of the camera under a default camera position parameter is displayed in a setting window 251, and the user adjusts the camera, so that the default camera position parameter is affected correspondingly, and further the preview shooting picture displayed in the setting window is changed, and when the change reaches the picture content expected by the user, the default camera position parameter is fixed, so that the setting of a camera position is completed. In fig. 2, the foreground in the preview shooting picture is a conference table and three communication participants, for example, the preset machine position is confirmed in the initial state corresponding to the default machine position parameter shown in fig. 2, and then the output picture of the preset machine position is actually a picture collected by the camera under the default machine position parameter. In fact, the state shown in fig. 2 may not be a picture actually required to be shared in the conference scene, at this time, the camera needs to be adjusted, the preview shooting picture 252 is first enlarged through the zoom control 253, so as to adjust the focal length of the camera, the zoom control is visually shown as enlarging from the center of the preview shooting picture 252 outwards, the new preview shooting picture shot by the adjusted camera is displayed in real time in the setting window 251, and visually, the new preview shooting picture is the central part of the preview shooting picture 252 before enlargement, at this time, if the new preview shooting picture 252 is not a picture required to be shared, as shown in fig. 3, the camera needs to be adjusted through the moving control 254, and at the same time, the preview shooting picture shot in real time after camera adjustment is displayed in the setting window 251 until the ideal shared picture is presented in the setting window 251. In the operation process through the moving control 254, if it is desired to adjust the camera, so that the image shot by the camera is located in the range where the edge of the preview shot image 252 is smaller, the focal length of the camera needs to be adjusted through the zoom control 253, and after the preview shot image 252 is enlarged by a larger multiple, the camera can shoot an ideal shared image through moving the moving control 254 for a larger number of times. In this process, although the preview shot picture 252 after the adjustment of the camera can be displayed in real time, the presentation of the adjustment effect is incomplete and intuitive, if the preview shot picture of the adjusted camera is not the picture that the user wants to share, the adjustment needs to be readjusted, and sometimes the adjustment controls are adjusted to the limit condition and cannot be continuously adjusted, at this time, the adjustment of the camera needs to be reset, and the operation process is complicated. In addition, for the interactive flat plate, because the initial picture collected by the camera is generally a wide-angle picture of the external environment such as a conference room, when the image collection is required to be carried out on a specific area in a video conference, the satisfactory effect can be achieved by carrying out multiple times of adjustment, the efficiency is low, and the overall adjustment speed and the adjustment accuracy are poor when the camera is adjusted.

The camera adjusting method provided by the embodiment of the application is suitable for the integral design scheme of the interactive flat panel, and can be realized on the interactive flat panel by software and/or hardware.

The following describes each embodiment in detail.

Fig. 1 is a flowchart of a method for adjusting a camera according to an embodiment of the present application, as shown in fig. 1, where the method for adjusting a camera includes:

Step S101, receiving a first trigger operation, displaying a first setting window, wherein a first preview picture acquired by a camera is displayed in the first setting window, and a selection frame is displayed on the first preview picture.

The embodiment of the application realizes man-machine interaction when the camera is adjusted based on an interface. The interface refers to an application program used for receiving and/or displaying information, such as an application of a video playing class, wherein the interaction interface is mainly used for displaying changed video pictures, an application of a real-time communication class, the interaction interface is mainly used for receiving content input by a near-end user and displaying content input by a far-end user, an application of a file editing class, the interaction interface is mainly used for receiving content input by the user and displaying the content input by the user, and an application of a browser class, the interaction interface is mainly used for receiving keywords input by the user and displaying webpage content obtained based on the keywords.

The camera adjusting method is applied to setting applications attached to a system or various third party applications needing to use the camera, and the corresponding interface is a user interface presented in the process of adjusting the camera. The system-attached setting application is an integrated management application that sets various states of the system, such as a display state, a sound state, and the like. And through the setting application attached to the system, the setting items are operated step by step, and finally, the camera position setting interface is opened to adjust the camera. Of course, the camera can be adjusted by providing a camera position setting interface in a video conference application which is independently and specially installed. The interface for realizing camera adjustment is the same as the position setting interface in the embodiment of the application, regardless of the application. For example, as shown in fig. 2 and 3, the machine position setting interface is the existing machine position setting scheme. In different operation links for adjusting the camera, the camera position setting interface can display different interface elements, such as various windows, controls and the like, so that a user can check the adjusting effect, continue adjusting the camera or confirm that the adjustment is completed in the process of adjusting the camera.

Before the camera adjustment is specifically performed, when the operation corresponding to the camera adjustment item or the operation of the special control is received, namely, the camera position setting interface is opened, and when the camera position setting interface is opened, the camera position setting interface can synchronously display the newly-added control as a trigger entry for realizing the camera adjustment in the embodiment of the application. The default machine position can be displayed in the machine position setting interface, and an output picture of the default machine position is a picture acquired by the camera under default parameters. And the camera position setting interface can also simultaneously display a preview shooting picture of the camera, and the preview shooting picture is used as a preview of an output picture of a default camera position and is used as a preview of a currently acquired picture by a user. In specific implementation, an independent window can be displayed after triggering setting, and corresponding independent windows are displayed when different adjustment stages are entered. The exemplary illustration is in the embodiment of the application with a window display based on a machine level setting interface, which is substantially the same as the implementation in a separate window.

The first trigger operation may be a trigger operation of a shortcut button control set in a window of a third party application using a camera or a trigger operation of a new control in a machine position setting interface or a trigger operation of other gestures or physical buttons. For example, when a trigger operation acting on a newly added control is received, the first trigger operation is confirmed to be received, as a response to the trigger operation, a first setting window is displayed, and a preview shooting picture of the camera is displayed in the first setting window, that is, a user can see a complete picture acquired under a default position in the first setting window. The first preview picture in the first setting window has the maximum picture range, based on the maximum picture range, a user can quickly and coarsely confirm the target area which needs to be acquired by the camera, and correspondingly, the maximum range shot in the first preview picture is kept unchanged.

The selection frame is a tool for realizing rough setting of the first preview picture by a user, the selection frame is rectangular, the aspect ratio of the selection frame is the same as that of a common video playing window or screen, for example, 16:9, 15:9, 16:10 and the like, and in the specific implementation process, various selectable selection frames can be provided, and the user selects one of the selection frames to be used as the currently used selection frame through selection operation. The adjustable means that the selection frame displays interactive attributes, the selection frame can realize adjustment within the display range of the preview shooting picture according to the operation of a user, and the specific adjustment comprises zoom adjustment and translation adjustment which are responded according to the operation of the user, wherein the length-width ratio is kept unchanged in the zoom adjustment process, namely, the length-width ratio of the selection frame is kept unchanged under the condition that the selection frame is not switched.

It should be noted that, in the first setting window, a focusing control may also be set, if the user considers that the range of the preview shooting picture generated based on the default machine position parameter is too large, the details are not clear enough, the preview shooting picture can be directly adjusted first by the focusing control, so as to obtain a preview shooting picture with unchanged picture size, smaller shooting range and clearer details, and the specific implementation is the same as the implementation mode based on the focusing control in the subsequent second setting window and third setting window.

In a specific display mode, the first setting window is a full-screen window or a partial window, the full-screen window is displayed with a restoration control, and the partial window is provided with the full-screen control, and the corresponding camera adjusting method further comprises the steps of switching the first setting window to be displayed with the partial window when a trigger operation acting on the restoration control is received under the condition that the first setting window is displayed with the full-screen window, and switching the first setting window to be displayed with the full-screen window when the trigger operation acting on the full-screen control is received under the condition that the first setting window is displayed with the partial window. In the first setting window, a first preview picture is displayed, the shooting range corresponding to the first preview picture is probably larger, when the first preview picture is displayed in a smaller first setting window (namely, a local window), the operation precision is too low, and at the moment, the first preview picture can be displayed in a full screen manner through a full screen control in the local window (namely, a full screen window), so that more accurate viewing and operation are realized. Correspondingly, when the trigger operation of the restoration control is received on the basis of full-screen window display, the display of the partial window is restored, so that rough setting can be completed in a small-range operation.

Step S102, receiving an adjustment operation on the selection frame, and adjusting the closed area of the selection frame according to the adjustment operation.

The adjustment operation of the selection frame mainly comprises two operation types, wherein the first operation type is the dragging operation of the position of the selection frame to realize the movement operation of the selection frame, and the second operation type is the dragging operation of the position of four corners to realize the zooming operation of the selection frame, and the two operation types can both adjust the closed area of the selection frame. The operation ranges of both operation types are constrained to the display range of the first preview screen, that is, constrained to the first setting window range. For touch operation, for example, when a finger is used as a touch object, the size and shielding of the touch object can affect the accuracy of user operation, and the position of the selection frame is adjusted on the basis of displaying a first preview screen on the first setting window, so that the actual closed area may occupy a small proportion, details of the screen cannot be clearly checked, fine operation cannot be realized on the basis of clearly checking the details, and therefore, the adjustment operation can be regarded as rough setting when the camera is adjusted. Visually, the adjustment operation based on the selection frame is to select a part of screen content from the first preview screen.

The confirmation of the closed area corresponding to the selection frame may be performed by an adjustment operation directly acting on the selection frame, or may be performed by receiving a third movement operation acting on the first preview screen, and adjusting the screen content of the first preview screen in the selection frame according to the third movement operation. The relative positional relationship between the selection frame and the first preview screen may be achieved by adjusting the selection frame or by adjusting the first preview screen.

Step S103, after receiving the first confirmation operation, adjusting the camera position parameters according to the selection frame, and displaying a second setting window, wherein a second preview picture acquired by the camera is displayed in the second setting window, and the second preview picture is consistent with the picture content selected by the frame in the selection frame.

For the camera, which range is used for image acquisition to obtain a picture depends on the machine position parameters. The machine position parameter refers to a physical state parameter of an electric control device in the camera when image acquisition is performed, and specifically may include one or more of a position parameter, an angle parameter and a focal length parameter. The position parameter is a physical position parameter of an electric control device driving the camera to translate when image acquisition is performed, for example, the translation distance of each direction, the specific translatable distance and direction are determined according to the movement distance and movement direction supported by the related electric control device, and the parameter determines the translation change of an acquisition area when the camera performs image acquisition and is generally controlled through a sliding rail. The angle parameter is an angle parameter of an electric control device driving the camera to rotate when the image acquisition is carried out, and specifically the rotatable angle and direction are determined according to the rotation distance and rotation angle supported by the related electric control device, the rotation change of an acquisition area when the camera carries out the image acquisition is determined by the angle parameter, and the cradle head can move on the sliding rail generally through cradle head control. The focal length parameter refers to a distance parameter between lenses determined by an electronic control device for adjusting the distance between each lens in the camera when image acquisition is performed, and the changeable focal length range is determined according to the moving range supported by the related electronic control device and the optical parameter of the lens, and the parameter determines the depth of field change when the camera performs image acquisition, in general, the larger the focal length is, the smaller the range of an acquisition area when image acquisition is performed.

The first confirmation operation may be triggered by a first confirmation control which is displayed in a normalized manner in the first setting window, or may be triggered by the first confirmation control which is temporarily displayed after the specific operation on the selection frame is finished, and when the first confirmation operation is received and the confirmation operation acting on the first confirmation control is acted on, the first confirmation operation is confirmed to be received, which is equivalent to that the user confirms that the setting in the first setting window is completed, and the subsequent adjustment can be performed.

The image acquisition of which range is carried out to obtain the picture depends on the machine position parameter, and correspondingly, the machine position parameter can be confirmed reversely under the condition of confirming the camera-related static parameter according to the picture obtained by the image acquisition. In step S102, a part of the screen content is visually selected from the first preview screen through the selection frame, but the size and position of the selection frame in the first preview screen are determined, and according to the size proportional relationship between the selection frame and the first preview screen, when the focal length of the first preview screen has been confirmed, the focal length required for image acquisition of the area corresponding to the selection frame can be confirmed, and according to the offset distance between the center of the selection frame and the center of the first preview screen, the position and/or angle of the camera required to be adjusted can be confirmed. The confirmed information is the position parameter obtained according to the selection frame, and is also the target parameter when the camera is regulated after the first confirmation operation is received, the preview picture collected by the camera under the target parameter is a second preview picture, and the second preview picture is displayed on the second setting window, so that rough regulation of the camera is completed.

In the adjustment process, the size and the position of the selection frame are adjusted at least once respectively in terms of vision and interaction, namely, the camera position parameters of the camera can be adjusted to be generally aligned to the range which needs to be shared by the user by total two times of adjustment. Compared with the prior art, the focal length and the angle and/or the position can be adjusted according to the preset step length for many times, the scheme can realize quick and accurate operation, and the adjusting speed and the adjusting accuracy when the camera is adjusted in the rough setting stage are integrally improved.

It should be noted that, in the embodiment of the present application, the content of the pictures is consistent, which means that the final imaging data is not identical, or the scaled image data is identical, but the content of the pictures is substantially identical. For the camera, image acquisition is performed on a smaller area after rotating a certain angle, and image acquisition is performed on an angle area comprising the smaller area before rotating a certain angle, because of the change of a shooting angle, the image acquired after rotating the angle may not be reduced and then completely overlapped with the corresponding area of the image acquired before rotating the angle, but the image caused by the hardware of the camera is slightly different, because the step S102 is used for realizing rough setting, and implementation of the scheme is not affected.

When the user confirms that the rough setting of the first setting window is close to the ideal output screen range, the fine setting can be entered by the first confirmation operation. And for the interactive tablet, when the first confirmation operation is received, displaying a second setting window for the user to perform fine setting. The second setting window may be set slightly smaller than the first setting window, as large as the first setting window, or larger than the first setting window.

Step S104, receiving a first moving operation acting on the second setting window, adjusting the camera position parameter of the camera according to the first moving operation, and displaying a third preview picture acquired after the camera is adjusted in the second setting window.

On the basis that rough setting is completed, a picture acquired by the camera according to the position parameters confirmed by the moving operation (namely a second preview picture) is displayed in the second setting window, and the second preview picture is close to an ideal output picture of a user, fine operation can be performed in the second setting window, and the ideal output picture of the user can be accurately and quickly realized. Specifically, the user may perform the first moving operation in the second setting window, adjust the shooting range of the camera in the same direction and the same distance (or the distance with a preset proportion) according to the direction and the distance of the real-time position of the first moving operation relative to the starting point of the first moving operation, and then reconfirm the preview screen (i.e. the third preview screen) to display the preview screen in the second setting window, so that the user can see the latest and clear-detail screen adjusted according to the first moving operation in the second setting window, thereby accurately and quickly implementing the ideal output screen of the user. In the embodiment of the application, the first preview screen and the second preview screen are screens which are kept unchanged after initial generation, the third preview screen is changed according to the first moving operation, and the second preview screen and the third preview screen are display screens in different stages in the second setting window, wherein the second preview screen is an initial display screen in the second setting window, and the third preview screen is a display screen which is changed and is subsequent on the basis of the second preview screen.

The method comprises the steps of receiving a first trigger operation, displaying a first setting window, displaying a first preview picture acquired by a camera in the first setting window, displaying a selection frame on the first preview picture, receiving an adjustment operation acting on the selection frame, adjusting a closed area of the selection frame according to the adjustment operation, adjusting a position parameter of the camera according to the selection frame after receiving a first confirmation operation, displaying a second setting window, displaying a second preview picture acquired by the camera in the second setting window, wherein the second preview picture is consistent with picture content selected by a frame in the selection frame, receiving a first moving operation acting on the second setting window, adjusting the position parameter of the camera according to the first moving operation, and displaying a third preview picture acquired after the camera is adjusted in the second setting window. When the camera position is set, rough setting and fine setting are respectively carried out through the first setting window and the second setting window in sequence, the rough setting can rapidly realize comprehensive adjustment of the azimuth angle and the focal length of the camera through one-time operation of the selection frame, and the fine setting can accurately carry out detail adjustment under the condition of approaching ideal output, so that the adjusting speed and the adjusting accuracy when the camera is adjusted are integrally improved

On the basis of finishing the fine setting in step S104, after receiving the second confirmation operation, closing the second setting window, displaying the machine position setting interface, adding a preset machine position identifier to the machine position setting interface, wherein the machine position parameter of the camera corresponding to the preset machine position identifier is the machine position parameter when the picture shot by the camera is the third preview picture, and the preset machine position identifier displays the thumbnail of the third preview picture. And when the user confirms that the fine setting of the second setting window has realized the ideal output picture, triggering the second confirmation control to finish the camera position setting. And for the interactive tablet, when receiving the triggering operation acting on the second confirmation control, returning to the machine position setting interface for the user to check all the latest preset machine positions. The second confirmation control may be displayed in a normalized manner, or may be displayed temporarily after each specific first movement operation is completed, in the same manner as the first confirmation control.

After returning to the machine position setting interface, the user may execute step S102 to step S104 again to set a new machine position, or may close the machine position setting interface, and use any preset machine position in a scene, such as a video conference scene, where the camera needs to be specifically called. The output picture of the preset camera position is a picture generated by calling and adjusting the camera to collect images according to the correspondingly stored camera position parameters.

It should be understood that if focusing is performed in the first setting window as described above, the parameters after focusing should be recorded to the preset machine position identifier as a basis for realizing the predetermined picture output by the preset machine position.

As an optional implementation manner, the preset machine position identifier is displayed with an editing control, and further adjustment of the existing preset machine position can be achieved based on the editing control. The camera adjusting method based on the display of the editing control further comprises a step S105-a step S108 for realizing further adjustment of the existing preset machine position.

Step S105, receiving a second trigger operation acting on the editing control, and displaying a third setting window, wherein the third setting window displays a third preview picture acquired by the camera.

In terms of interaction requirements, the user further adjusts the existing preset machine position, and the possibility is high because the output picture of the existing preset machine position has small deviation from the ideal output picture, and the deviation is small, so in the embodiment, the design and interaction of the third setting window are similar to those of the second setting window, and the fine adjustment of the camera is realized through the fine setting, so that the fine adjustment of the output picture is performed.

Step S106, receiving a second moving operation acting on the third setting window, adjusting the camera position parameter of the camera according to the second moving operation, and displaying a fourth preview picture acquired after the camera is adjusted in the third setting window.

And S107, after receiving the third confirmation operation, closing the third setting window, displaying the machine position setting interface, updating the preset machine position identification on the machine position setting interface, wherein the machine position parameter of the camera corresponding to the updated preset machine position identification is the machine position parameter when the picture shot by the camera is the fourth preview picture, and the updated preset machine position identification displays the thumbnail of the fourth preview picture.

In the operation of the third setting window and the receiving of the third confirmation operation, the operation of the second setting window and the receiving of the first confirmation operation and the second confirmation operation may be referred to, for example, by normalizing the displayed third confirmation control or the temporarily displayed third confirmation control, and receiving the third confirmation operation.

In the embodiment, the preset machine position identifier or the third setting window may further display a deletion control, and the camera adjusting method further includes step S108:

And S108, returning to the machine position setting interface when receiving a third trigger operation acting on the deleting control, and deleting the target preset machine position identification confirmed by the third trigger operation.

After deleting a preset machine position identifier, directly returning to the machine position setting interface, and executing any embodiment of the application based on the machine position setting interface after returning to the machine position setting interface.

In specific implementation, the deletion control can be displayed directly at the same time as the editing control in the preset machine position identification, and if the deletion operation is performed, the deletion operation is triggered directly at the preset machine position identification. Another alternative implementation manner is to set only a deletion control on the preset machine position identifier, and delete the unnecessary preset machine position directly, and the new preset machine position is needed to be created directly through steps S101-S104.

In the specific implementation process, one or more of the first setting window, the second setting window and the third setting window can also set a closing control, when a fourth triggering operation acting on the closing control is received, a prompt window is popped up, a storage control and a cancellation control can be set in the prompt window, if a fifth triggering operation acting on the storage control is received, a preset machine position identification is stored and returned to the machine position setting window, and if a sixth triggering operation acting on the cancellation control is received, the current setting operation is ended and the machine position setting window is returned. Of course, the sixth trigger operation on the cancel control is received, or the preset machine position setting may be continued after the closing process is exited. In addition, when the fourth trigger operation acting on the closing control is received, the prompt box is not popped up, but the current setting operation is directly ended, and the machine position setting window is returned.

In the specific implementation process, one or more of the first setting window, the second setting window and the third setting window can also display an elimination control, when a seventh trigger operation acting on the elimination control is received, the existing operation in the current setting window is eliminated, the original state of entering the setting window is restored, a user can quickly reset the current setting link, and camera adjustment is flexibly performed.

In addition, a direct saving control can be set in the first setting window, when the triggering operation acting on the direct saving control is received, the region confirmed by the selection frame in the first setting window can be saved as a preset machine position directly, and the machine position setting interface is returned to finish the current setting operation.

In another optional implementation manner, a focusing control is displayed in the second setting window and/or the third setting window, correspondingly, after the second setting window or the third setting window is displayed, a focusing trigger operation acting on the focusing control is received, the camera position parameter of the camera is adjusted according to the focusing trigger operation, and a fourth preview picture acquired after the camera is adjusted is displayed in the third setting window. For a shooting preview picture acquired by a camera based on default hardware parameters, the shooting preview picture with the largest shooting range is usually the shooting preview picture with the largest shooting range, and for a user, the preview picture in the range may contain a too large proportion of background pictures, the occupation ratio of a foreground picture which can be set for sharing is too small, and at the moment, the focal length of the camera can be adjusted through a focusing control, so that the occupation ratio of the foreground picture in the whole shooting preview picture is correspondingly changed.

In the interactive flat panel, the camera may actually realize the image acquisition function in a mode of combining a plurality of lenses, and different lenses are combined with lenses with different parameters to realize different imaging advantages, for example, the advantages of a wide-angle lens are displayed in a panoramic view, the advantages of a long-focus lens are focused in a long distance, and the like. The camera can be regarded as comprising at least two sub-cameras with different focal ranges, correspondingly, the sub-cameras which are matched with the target focal length confirmed by the focusing triggering operation are called according to the focal range after the triggering operation acted on the focusing control is received, and the camera position parameters of the cameras are adjusted according to the target focal length, which is equivalent to the imaging of each sub-camera, and the proper sub-camera is selected to obtain the optimal imaging effect. When the sub-cameras with the target focal length being adapted are switched, space mapping is carried out according to camera coordinate systems of the sub-cameras before and after switching, and pictures of the same area in the world coordinate system are collected through the sub-cameras after switching to be used as a second preview picture or a third preview picture.

In the upper layer application of implementing the camera position setting interface, the interaction panel provided with the wide angle lens and the tele lens can display the picture captured by the camera through the wide angle lens in the camera position setting interface by default after the data interface provided by the browser, such as navigator. Then, entering different setting windows, the user can adjust the size of the selectable region or set the magnification factor (the length-width ratio is always kept at 16:9) according to the needs, an ideal output picture wanted by the user is obtained, and the interactive flat board stores the positions (such as the left upper corner coordinate and the right lower corner coordinate) of the frame selected region. Correspondingly, the camera position parameters of the preset camera position also comprise the identification and the focal length of the sub-cameras.

On the basis that camera adjustment is completed and the adjusted camera position parameters are stored as a preset camera position, a default camera position identification and a preset camera position identification can be displayed when a camera position selection interface is opened, clicking operation on the preset camera position identification is received, camera position parameters corresponding to the preset camera position identification confirmed by the clicking operation are obtained, and camera positions of the cameras are adjusted according to the obtained camera position parameters. The use of the preset machine position can be realized through the steps S109-S111.

Step S109, when the machine position selection interface is opened, the machine position identification is displayed, wherein the machine position identification comprises default machine position identification and preset machine position identification, and each preset machine position identification correspondingly records machine position parameters of a preset machine position.

The camera position selection interface may be displayed by triggering the camera control 201 shown in fig. 4, that is, when a triggering operation acting on the camera control 201 is received, the camera position selection interface is displayed, where the camera position selection interface is used to display all available preset camera position identifiers. Based on preset machine positions, the calling camera is arranged outside the default machine position, at least one preset machine position is arranged in addition, and at a machine position selection interface, the default machine position and the preset machine position are provided with corresponding machine position identifiers, namely the default machine position identifier and the preset machine position identifier, wherein the calling of the default machine position is the same as that of the prior art, repeated description is not needed, and the calling of the preset machine position needs to acquire corresponding machine position parameters to call the camera to generate corresponding output pictures.

Step S110, when receiving triggering operation acting on any preset machine position identifier, obtaining the machine position parameter corresponding to the preset machine position identifier.

And receiving triggering operation acting on any preset machine position identifier, and correspondingly acquiring the machine position parameter of the record corresponding to the preset machine position identifier where the triggering operation is located.

And step S111, calling and adjusting a camera to acquire images according to the acquired camera position parameters.

On the basis of acquiring the machine position parameters, according to the target sub-cameras (if a plurality of sub-cameras exist) recorded in the machine position parameters and the parameter information of each dimension, the target sub-cameras are called to finish focusing, direction rotation and translation adjustment according to the parameter information of each dimension, and after the adjustment is adjusted to the corresponding shooting state, the acquired picture in the state is used by the application of the current calling camera. Referring to fig. 5-10, the following is a visual presentation based on fig. 5-10, illustrating an exemplary implementation of the process of the present embodiment in an interactive tablet disposed in a conference room.
