firstly, after a terminal a starts a video picture sharing function, the terminal a starts to acquire video images in real time and determine position information in real time, and the video images acquired in real time and the position information determined in real time are uploaded to a cloud server; the cloud server detects whether a video picture corresponding to the video image uploaded by the terminal a contains a target object, if so, the position information of the terminal b and the terminal c can be sent to the terminal a, and the position information can represent the actual position of the terminal in an application scene;

Secondly, after receiving the position information of the terminal b and the terminal c sent in the cloud server, the terminal a can display an AR video picture containing the AR object according to the position information of the terminal b and the terminal c and the currently acquired video image, wherein the AR object contains the position identifiers corresponding to the terminal b and the terminal c respectively, and the position identifiers are used for representing the relative positions between the terminal b and the terminal c and the target object respectively; it should be understood that the embodiments of the present disclosure are not limited to the shape, color, size, etc. of the AR object and the location identifier, for example, the AR object may be disc-shaped, fan-shaped, ring-shaped, etc., the location identifier may be drop-shaped, dot-shaped, etc., and the location identifier may further include a user avatar, etc.;

then, after the terminal a displays the AR video frame, the user holding the terminal a may click on any position identifier, which is equivalent to selecting any terminal sharing the video frame, for example, if the user selects the terminal c, the cloud server may send the device number corresponding to the terminal c to the cloud server, the cloud server may transmit the video image acquired by the terminal c indicated by the device number to the terminal a in real time, and the terminal a may display the corresponding video frame based on the video image acquired by the terminal c in real time. Wherein the device number may be used to distinguish between different terminals and location information of the terminals.

It should be understood that, the above-mentioned terminal b and terminal c will also display the AR object, the user holding the terminal b may select to view the video picture captured by the terminal a or the terminal c through the displayed position identifier on the AR object, and the user holding the terminal c may also select to view the video picture captured by the terminal a or the terminal b through the displayed position identifier on the AR object.

It should be understood that the user may start the video picture sharing function by holding an application program installed on the terminal and having the video picture sharing function, that is, by applying the video picture sharing method in the present disclosure, and the application program may include, for example, a social application, a camera application, an AR application, and the like, which is not limited to the embodiment of the present disclosure.

One skilled in the art may develop an application program for implementing the video frame sharing method in the present disclosure by using a software development technology known in the art, and may further provide related controls for stopping watching video frames captured by other terminals or stopping operations such as a video frame sharing function in the application program, so as to meet various operation requirements of users.

It should be noted that the above application scenario is a scenario provided by the embodiments of the present disclosure, and in fact, any user in the scenario may share a video picture captured by the application software with a video picture sharing function installed on the terminal, or may also view a video picture captured by any other terminal that has started a video picture sharing function. Any terminal in the video picture sharing method can be used as a sharer for sharing video pictures shot by the terminal, and also can be used as a viewer for watching video pictures shot by other terminals.

Fig. 2 shows a flowchart of a video picture sharing method according to an embodiment of the present disclosure, where the video picture sharing method is applied to a first terminal, which may be a terminal device such as a User Equipment (UE), a mobile device, a User terminal, a cellular phone, a cordless phone, a personal digital assistant (Personal Digital Assistant, PDA), a handheld device, a computing device, a wearable device, etc., by a processor of the first terminal invoking computer readable instructions stored in a memory. As shown in fig. 2, the video picture sharing method includes:

In step S11, in response to an instruction to start the video frame sharing function, position information of at least one second terminal, which is a terminal that is capturing and sharing a video image including a target object, is acquired from the cloud server.

As described above, the user can start the video sharing function through the application program with the video sharing function installed on the first terminal, and after the video sharing function is started, the position information of the other second terminal that is acquiring the video image including the target object and sharing the video image can be acquired from the cloud server.

It should be understood that each second terminal may be provided with an image sensor such as a camera to capture video images, i.e. to capture a target object. A video image may be understood as video data collected by an image sensor for transmission, the video image may be represented in the form of a video stream, and a video frame may be understood as a continuous frame of multiple frames of video images visible to the naked eye, where those skilled in the art may use video processing techniques known in the art to convert multiple frames of video images into video frames and display them, or decode them into video frames and display them, and the embodiments of the present disclosure are not limited.

The location information may represent an actual spatial location of the terminal, for example, may be location information determined by a global positioning system (Global Positioning System, GPS) of the terminal, or may also be location information determined by performing visual positioning based on an acquired video image, where a determination manner of the location information is not limited in the embodiments of the present disclosure.

In one possible implementation manner, before the position information of at least one second terminal is obtained from the cloud server in response to an instruction for starting the video frame sharing function, the method further includes: responding to an opening instruction of a video picture sharing function, and acquiring a first video image acquired by a first terminal in real time; and transmitting the first video image to the cloud server, so that the cloud server feeds back the position information of at least one second terminal to the first terminal under the condition that the cloud server detects that the first live-action video picture corresponding to the first video image contains the target correspondence. By the method, the AR video picture can be displayed by returning the position information of the second terminal when the user shoots the target object, the AR object displayed along with the target object is presented to the user, and user interaction experience is improved.

After the first terminal starts the video picture function, the first terminal can acquire the first video image in real time and upload the first video image acquired in real time to the cloud server, the cloud server can identify and detect the first video image acquired in real time by the first terminal so as to detect whether a first live-action video picture corresponding to the first video image contains a target object, namely, judge whether the first terminal shoots the target object, and then return the position information of at least one second terminal to the first terminal under the condition that the first terminal detects that the first live-action video picture corresponding to the first video image contains the target object or the first terminal shoots the target object.

In one possible implementation manner, after the first terminal starts the video frame sharing function, the first terminal may further determine its own location information in real time, and upload the location information determined in real time to the cloud server, where the cloud server may further determine, according to the location information of the first terminal, whether the first terminal is within a specified geographic range (for example, within a theatre range, within a competition field range, etc.), and if the first terminal is within the specified geographic range, return the location information of at least one second terminal to the first terminal. Alternatively, when it is detected that the first terminal is capturing the target object (that is, when it is detected that the first live-action video frame corresponding to the first video image includes the target object) and the first terminal is within the specified geographic range, the location information of at least one second terminal may be returned to the first terminal.

When the cloud server returns the position information of at least one second terminal to the first terminal, the device numbers corresponding to the second terminals can be returned at the same time, and the device numbers can be used for distinguishing different second terminals and the position information of the different second terminals, so that target video images acquired by the selected second terminals can be acquired from the cloud server conveniently.

As described above, after the first terminal starts the video frame sharing function, the first terminal may collect the first video image in real time and determine its own position information in real time, and upload the first video image collected in real time and the position information determined in real time to the cloud server. In consideration of the above, there may be a case where the first terminal does not include the target object (i.e., the first terminal may not currently be shooting the target object) in the first live-action video frame corresponding to the first video image uploaded by the first terminal, and/or the first terminal is not within the specified geographic range.

Based on this, in one possible implementation manner, if the cloud server detects that the first live-action video frame corresponding to the first video image acquired by the first terminal does not include the target object, and/or the first terminal is not within the specified geographic range, the cloud server may not send the position information of the at least one second terminal to the first terminal, or stop sending the position information of the at least one second terminal to the first terminal; the first terminal may display a first live-action video picture corresponding to the first video image currently collected by the first terminal when the cloud server does not return the position information of the at least one second terminal, until the cloud server detects that the first live-action video picture corresponding to the first video image collected by the first terminal already contains the target object, and/or returns the position information of the at least one second terminal to the first terminal when the first terminal is already within the specified geographical range.

In step S12, according to the position information of the at least one second terminal and the first video image acquired by the first terminal in real time, an AR video frame including an AR object is displayed, where the AR object includes a position identifier for characterizing a relative position between the at least one second terminal and the target object.

In one possible implementation manner, displaying an AR video frame including an AR object according to the location information of at least one second terminal and the first video image acquired by the first terminal in real time may include: generating an AR object according to the position information of the second terminal; and adding an AR object in the first live-action video picture corresponding to the first video image to obtain an AR video picture and displaying the AR video picture. The AR object may be added at a specified image position in the first live-action video frame, for example, an upper left corner, a lower right corner, or the like, or may be randomly added at a random image position in the first live-action video frame, which is not limited to the embodiment of the present disclosure.

Considering that the photographing angle of view of the first terminal may be changed, or that the image position of the target object in the first live-action video picture is changed, if the AR object is displayed at a specified image position or a random image position in the first live-action video picture, there may be a case where the target object is blocked. In one possible implementation manner, displaying an AR video frame including an AR object according to the location information of at least one second terminal and the first video image acquired by the first terminal in real time includes: generating an AR object according to the position information of the second terminal, and detecting an object area where a target object is located in a first live-action video picture corresponding to a first video image; according to the object area where the target object is located, adding AR objects around the target object in the first live-action video picture, obtaining an AR video picture and displaying the AR video picture. By the method, the AR object can be displayed around the target object according to the image position of the target object, or the AR object is displayed along with the target object, so that better AR interaction experience is obtained.

As described above, the AR object may be, for example, a disc shape, a sector shape, a ring shape, or the like; the location identifier may be a water drop, a dot, etc., and the location identifier may further include a user avatar, etc. It should be understood that the embodiments of the present disclosure are not limited to the shape, color, size, etc. of the AR object and the location identifier. The AR object can also display a position identifier representing the relative position between the first terminal and the target object, and can also display an object identifier corresponding to the target object, so that a user can conveniently and intuitively check the relative position of the AR object relative to the target object, and can conveniently and intuitively check the relative positions of other terminals relative to the target object or relative to the first terminal.

The AR object is generated according to the position information of the second terminal, which can be understood as that the AR object including the position identifier is drawn according to the actual spatial position of the second terminal and the actual spatial position of the target object; it should be understood that the actual spatial position of the target object may be known, after the actual spatial position of the target object and the actual spatial position of each second terminal are known, the relative position of each second terminal with respect to the target object may be determined, then the display position of the position identifier corresponding to each second terminal on the AR object may be determined based on the relative position, and the position identifier may be added to the AR object according to the display position of each position identifier, so as to obtain the AR object.

The object identifier for indicating the target object may be fixedly set at a default position of the AR object, for example, may be set at a middle position, a top position, a bottom position, and the like, and based on the default position of the object identifier, other position identifiers may determine a display position on the AR object according to a relative position of each second terminal with respect to the target object, and add the position identifier to the AR object according to a display position of each position identifier, so that the position identifier may represent a relative position of each second terminal with respect to the target object. It should be appreciated that the addition of the location identity of the first terminal to the AR object may be implemented with reference to the above-described implementation of adding the location identity of the second terminal to the AR object.

One skilled in the art may use a target detection technology known in the art to detect an object area where a target object is located in a first live-action video frame corresponding to a first video image, which is not limited in this embodiment of the disclosure. After the object region where the target object is located is detected, AR objects may be added around the target object in the first live-action video picture, so as to obtain an AR video picture and display the AR video picture. The AR object may be added around the target object in the first live-action video frame, for example, the AR object may be added at an image position such as a left side, a right side, an upper side, or a lower side of the target object, which is not limited to the embodiment of the present disclosure.

It should be understood that the actual spatial positions of the second terminals and the first terminals may change at any time, so that each of the second terminals and the first terminals may determine its own position information according to a preset frequency (for example, once every 1 minute) and upload the position information to the cloud server, the cloud server may push the position information uploaded by each of the second terminals to the first terminal in real time, and the first terminal may update the position identifier in the AR object according to the position information pushed by the cloud server in real time and the position information determined by itself in real time; and the cloud server can push the position information uploaded by the first terminal to each second terminal so as to update the position identification displayed on the AR object in each second terminal.

In one possible implementation manner, the first terminal may determine the location information of the first terminal in real time according to a preset frequency and send the location information of the first terminal to the cloud server, so that the cloud server pushes the location information of the first terminal to at least one second terminal. It should be understood that, each second terminal may also determine, in real time, the location information of the second terminal itself according to a preset frequency, and send the location information of the second terminal itself to the cloud server, so that the cloud server pushes the location information of the second terminal to the first terminal, so as to update, in real time, the location identifier on the AR object displayed in the first terminal. By the method, the AR objects displayed in each terminal with the video picture starting function can be updated in real time, so that a user can conveniently select to watch the live-action video picture currently shot by any other terminal.

In step S13, in response to a selection operation for any one of the location identifiers of the AR objects, a target video image acquired by the second terminal corresponding to the selected location identifier is acquired from the cloud server, and a target live-action video picture corresponding to the target video image is switched and displayed.

It should be understood that when the user selects any one of the location identifiers, this means that the user desires to view the live-action video picture taken by the second terminal corresponding to the location identifier, and the second terminal corresponding to the selected location identifier, that is, the selected second terminal. As described above, when the cloud server returns the location information of at least one second terminal to the first terminal, the device numbers corresponding to the second terminals may also be returned at the same time, where the device numbers may be used to distinguish different second terminals and location information of different second terminals.

Based on the above, after the user selects any position identifier, the device number of the second terminal corresponding to the selected position identifier may be sent to the cloud server, and the cloud server may transmit the target video image acquired by the second terminal corresponding to the device number to the first terminal based on the device number sent by the first terminal, that is, the target video image acquired by the second terminal corresponding to the selected position identifier is acquired from the cloud server.

As described in step S12 above, before the user does not select any location identifier, the display screen of the first terminal displays an AR video picture, and after the user selects any location identifier, the display screen may be switched to display a target live-action video picture corresponding to the target video image obtained from the cloud server, so as to view the target live-action video picture captured by the selected second terminal. In one possible implementation, a prompt may be displayed in an interface displaying the target live-action video picture, where the prompt may be used to prompt a user holding the first terminal to currently view the target live-action video picture taken by the selected second terminal.

It should be understood that if the first terminal has switched to display the target live-action video frame, the user will not shoot the target object with a high probability in the process of watching the target live-action video frame, that is, the first live-action video frame corresponding to the first video image collected by the first terminal does not include the target object, so that the first terminal can pause collecting the first video image and determining its own position information after having switched to display the target live-action video frame, and pause transmitting the first video image and its own position information to the cloud server, which can be understood as that the first terminal pauses the video frame sharing function.

After the first terminal has displayed the target live-action video picture, the user can also provide a virtual key in the application program or a physical key set by the first terminal, send a stop instruction for stopping watching the target live-action video picture to the first terminal, and the first terminal can respond to the stop instruction to stop acquiring the target video image from the cloud server and stop displaying the target live-action video picture.

In one possible implementation manner, after the user sends a stop instruction to stop watching the target live-action video frame through the virtual key or the physical key, a prompt popup window may be displayed in the interface of the first terminal, where the prompt popup window may be used to ask the user whether to continue to start the video frame sharing function, and if the user chooses not to continue to start the video frame sharing function, the steps of the video frame sharing method in the embodiment of the disclosure are not executed, that is, the video frame sharing function is exited.

If the user selects to continue to start the video frame sharing function, the first terminal may restart to collect the first video image, determine its own position information, upload the position information to the cloud server, and acquire the position information of at least one second terminal from the cloud server according to the steps S11 to S12, so as to redisplay the AR video frame. Of course, the user may continue to select any location identifier to view the live-action video frames shot by other second terminals through step S13, or may not select any location identifier and display the AR video frames, which is not limited in the embodiment of the present disclosure.

In some cases, the cloud server may further send a sharing stop instruction to the first terminal to notify the first terminal to stop displaying the target live-action video frame, for example, the live-action video frame corresponding to the target video image acquired by the selected second terminal does not include the target object, that is, the selected second terminal is not shooting the target object; or the selected second terminal has stopped transmitting the target video image to the cloud server, that is, the second terminal has stopped the video image sharing function, for example, the second terminal closes an application program with the video sharing function, the second terminal has selected to switch and display the live-action video images shot by other terminals, and the like. It can be understood that in these cases, the cloud server does not need to transmit the target video image acquired by the second terminal to the first terminal any more, so that the sharing stop instruction can be sent to the first terminal, and the first terminal can respond to the sharing stop instruction to perform corresponding processing.

In one possible implementation manner, after switching to display the target live-action video picture corresponding to the target video image, the method further includes: and stopping displaying the target live-action video picture in response to receiving a sharing stopping instruction sent by the cloud server, and acquiring the position information of at least one second terminal from the cloud server again to generate an AR video picture and display the AR video picture, wherein the sharing stopping instruction is used for representing that the target object is not contained in the target live-action video picture corresponding to the target video picture currently, or the second terminal corresponding to the selected position mark stops transmitting the target video picture to the cloud server. By the method, the situation that the selected second terminal is not shooting the target object or the selected second terminal stops transmitting the target video image to the cloud server can be effectively treated, and interaction experience is improved.

After receiving the sharing stop instruction sent by the cloud server, the first terminal may display a prompt pop-up window to prompt the user holding the first terminal that the second terminal does not shoot the target object any more, or prompt the second terminal to stop the video image sharing function, where the prompt pop-up window may also ask the user whether to continue to start the video image sharing function, and if the user chooses to continue to start the video image sharing function, the AR video image may be redisplayed according to the steps S11 to S13, and the live-action video images shot by other second terminals may be redisplayed. Of course, the user may not be asked to directly redisplay the AR video frames according to the steps S11 to S13, and choose to watch the live-action video frames shot by the other second terminals again, which is not limited in the embodiments of the present disclosure.

Fig. 3 shows a flowchart of a video picture sharing method according to an embodiment of the present disclosure, which is applied to a cloud server. As shown in fig. 3, the video picture sharing method includes:

in step S21, in response to receiving the first video image transmitted by the first terminal that has turned on the video picture sharing function, it is detected whether the first live-action video picture corresponding to the first video image includes the target object.

Among other things, image processing techniques known in the art, such as object detection, image recognition, etc., may be used to detect whether the first live-action video picture contains the target object, which is not a limitation of embodiments of the present disclosure.

In step S22, if the first live-action video frame includes the target object, the location information of at least one second terminal is sent to the first terminal, so that the first terminal feeds back the selected second terminal to the cloud server according to the location information of the at least one second terminal.

As described above, after the first terminal receives the position information of at least one second terminal sent by the cloud server, the first terminal may display an AR video frame including an AR object according to the position information of at least one second terminal and the first video image acquired in real time by the first terminal, a user holding the first terminal may select any position identifier, that is, select any second terminal, where the second terminal is a terminal that is acquiring a video image including a target object and sharing the video image, and the selected second terminal may be understood as a terminal that is capturing a live-action video frame by the second terminal that the user holding the first terminal desires to view.

As described above, after the user holding the first terminal selects any position identifier, that is, after any second terminal is selected, the first terminal may send the device number of the selected second terminal to the cloud server, so as to implement feedback of the selected second terminal to the cloud server.

It should be understood that the first live-action video picture corresponding to the first video image acquired by the first terminal may or may not include the target object; under the condition that the first video image is detected to not contain the target object, the cloud server can not send the position information of at least one second terminal to the first terminal or stop sending the position information of at least one second terminal to the first terminal until the first live-action video image is detected to contain the target object.

When the cloud server returns the position information of at least one second terminal to the first terminal, the cloud server can also return the device numbers corresponding to the second terminals at the same time, and the device numbers can be used for distinguishing different second terminals and the position information of the different second terminals.

In step S23, in response to receiving the selected second terminal fed back by the first terminal, the target video image acquired by the selected second terminal is transmitted to the first terminal.

As described above, when the cloud server returns the location information of at least one second terminal to the first terminal, the device numbers corresponding to the second terminals can be returned at the same time, the device numbers can be used for distinguishing different second terminals and the location information of different second terminals, the first terminal can send the device number of the selected second terminal to the cloud server, feedback of the selected second terminal to the cloud server is achieved, and the cloud server can transmit the target video image acquired by the second terminal corresponding to the device number to the first terminal based on the device number fed back by the first terminal, namely, the transmission of the target video image acquired by the selected second terminal to the first terminal is achieved.

In the embodiment of the disclosure, the cloud server pushes the position information of the other second terminals which are acquiring the video images containing the target object and sharing the video images to the first terminal which has any started the video image sharing function and is shooting the target object, so that a user holding the first terminal can select any interested second terminal based on the position information, the cloud server can transmit the target video image acquired by the second terminal selected by the user to the first terminal, and the first terminal can switch and display the target live-action video image corresponding to the target video image, thereby realizing video image sharing among the terminals, namely, any terminal can become a sharer sharing the live-action video image shot by the user and also become a viewer watching the live-action video image shot by other terminals, and being beneficial to improving the watching experience of watching the target object.

As described above, the first terminal may further determine its own location information in real time and upload the location information to the cloud server, and in one possible implementation manner, the method further includes: receiving the position information of the first terminal sent by the first terminal; and pushing the position information of the first terminal to at least one second terminal under the condition that the first live-action video picture contains the target object, so that the at least one second terminal updates the position identification on the respectively displayed AR object according to the position information of the first terminal. In this way, video picture sharing between the terminals is facilitated.

As described above, the first video sharing frame corresponding to the first video image uploaded by the first terminal after the first terminal starts the video frame sharing function may not include the target object, that is, the first terminal is not shooting the target object, and if the first terminal is not shooting the target object, the position information of the first terminal is not pushed to other second terminals that are acquiring and sharing the video image including the target object. And if the first live-action video picture contains the target object, namely the first terminal shoots the target object, pushing the position information of the first terminal to at least one second terminal.

It should be understood that, each second terminal may display the AR object by referring to the manner of displaying the AR video image in the first terminal, that is, when the first terminal is shooting the target object, the first terminal is opposite to any second terminal, that is, a terminal that is capturing the video image containing the target object and sharing the video image, so the cloud server may push the location information of the first terminal to each second terminal to update the location identifier on the AR object displayed in each second terminal.

As described above, the first terminal may upload its own location information to the cloud server, and in one possible implementation, the cloud server may further determine whether the first terminal is within a specified geographic range (e.g. within a theatre range, within a competition field range, etc.) according to the location information of the first terminal, and if the first terminal is within the specified geographic range, may return the location information of at least one second terminal to the first terminal. Alternatively, when it is detected that the first terminal is capturing the target object (that is, when it is detected that the first live-action video frame corresponding to the first video image includes the target object) and the first terminal is within the specified geographic range, the location information of at least one second terminal may be returned to the first terminal.

In a possible implementation manner, when the cloud server detects that the first live-action video frame corresponding to the first video image acquired by the first terminal does not include the target object, and/or the first terminal is not within the specified geographic range, the cloud server may not send the position information of the at least one second terminal to the first terminal, or stop sending the position information of the at least one second terminal to the first terminal.

As described above, the target object is not included in the target live-action video frame currently corresponding to the target video image acquired by the selected second terminal, that is, the selected second terminal is not shooting the target object; or the selected second terminal stops transmitting the target video image to the cloud server, that is, the second terminal stops the video image sharing function, for example, the second terminal closes an application program with the video sharing function, the second terminal selects to switch and display live-action video images shot by other terminals, and the like, in which case the cloud server does not need to transmit the target video image acquired by the selected second terminal to the first terminal, then the cloud server can send a sharing stop instruction to the first terminal, and the first terminal can respond to the sharing stop instruction to perform corresponding processing. In one possible implementation, the method further includes:

Receiving a second video image transmitted by at least one second terminal in real time and position information of the at least one second terminal, and respectively detecting whether a second live-action video picture corresponding to the second video image contains a target object or not, wherein the second video image comprises a target video image acquired by a selected second terminal;

and stopping transmitting the target video image to the first terminal under the condition that the target object is not contained in the target live-action video picture corresponding to the target video image currently or the selected second terminal stops transmitting the target video image, and sending a sharing stopping instruction to the first terminal so as to instruct the first terminal to stop displaying the target live-action video picture corresponding to the target video image.

It should be understood that after the video picture sharing function is started, each second terminal may collect the second video image in real time and determine its own position information in real time, and then upload the second video image collected in real time and its own position information to the cloud server, where the cloud server may detect the second video image uploaded by each second terminal, so as to detect whether the second live-action video picture corresponding to the uploaded second video image includes the target object.

The method for detecting whether the first live-action video picture corresponding to the first video image includes the target object may be referred to above, so as to detect whether the second live-action video picture corresponding to the at least one second video image includes the target object, which is not limited in this embodiment of the disclosure.

In the embodiment of the disclosure, the situation that the selected second terminal does not shoot the target object any more or the selected second terminal stops transmitting the target video image to the cloud server can be effectively treated, and the interactive experience is improved.

In one possible implementation manner, the video picture sharing function of the embodiment of the present disclosure may be applied to a video picture sharing scene for a landscape, and specifically, when a viewer (equivalent to a first terminal) performs video watching on some landscape, the video picture sharing function may be turned on, for example, by clicking an AR sharing button in an application program, so that a photographed live-action video picture may be shared out; meanwhile, an AR disc (namely an AR object) is displayed beside the landscape in the real-scene video picture, other sharers (corresponding to a second terminal) which are sharing the video picture are contained on the AR disc, the positions of the viewers and the positions of the other sharers are displayed according to the positions relative to the landscape, and the real-scene video picture shot by the sharers can be switched and displayed in real time by selecting any sharer.

According to the embodiment of the disclosure, the AR disc can be generated around the live-action video picture containing the target object according to the position information of the sharer, a viewer can click to select any sharer, and the live-action video picture shot by the selected sharer can be watched in real time.
