[0074] Research has found that in the virtual live broadcast scenario, real people can control virtual characters to perform related actions to broadcast live through virtual characters. In related technologies, in order to enrich the live broadcast effect, multiple cameras can be used for virtual live broadcast. Therefore, how to control multiple virtual cameras during the live broadcast process to ensure the live broadcast effect of virtual live broadcast has become a technical problem that needs to be solved urgently in this field.

[0075] Based on the above research, the present disclosure provides a live broadcast control method, device, computer equipment and storage medium. By determining the task type and shooting area corresponding to the received live broadcast task, a virtual camera group corresponding to the task type can be selected according to the determined task type, and each virtual camera in the virtual camera group can be directed and controlled according to the camera movement trajectory corresponding to the task type. In this way, by selecting and directing virtual cameras according to the task type and shooting area, it can be determined that the virtual camera used in the live broadcast process can meet the live broadcast requirements corresponding to the task type and shooting area; on the other hand, since the virtual camera group contains multiple virtual cameras with different shooting postures, the live broadcast images under different shooting angles can be controlled during the live broadcast process, thereby enriching the live broadcast viewing experience of the live broadcast audience and ensuring the live broadcast effect when using virtual characters for virtual live broadcasts.

[0076] To facilitate understanding of this embodiment, a live broadcast control method disclosed in the embodiment of the present disclosure is first introduced in detail. The execution subject of the live broadcast control method provided in the embodiment of the present disclosure is generally a computer device with certain computing capabilities, and the computer device includes, for example: a terminal device or a server or other processing device, and the terminal device can be a user equipment (UE), a mobile device, a user terminal, a terminal, a handheld device, a computing device, a vehicle-mounted device, a wearable device, etc. In some possible implementations, the live broadcast control method can be implemented by a processor calling a computer-readable instruction stored in a memory.

[0077] See also Figure 1As shown, it is a flowchart of the live broadcast control method provided by the embodiment of the present disclosure, and the method includes S101 to S103, wherein:

[0078] S101: In response to receiving a live broadcast task, determining a task type and a shooting area corresponding to the live broadcast task.

[0079] S102: According to the task type, select a virtual camera group corresponding to the task type; wherein the virtual camera group includes multiple virtual cameras selected from virtual cameras corresponding to the shooting area, and different virtual cameras have different shooting postures.

[0080] S103: Performing broadcast control on each virtual camera in the virtual camera group according to the camera movement trajectory corresponding to the task type.

[0081] The following is a detailed description of the above steps.

[0082] The process of determining the task type and shooting area corresponding to the live broadcast task of S101:

[0083] Here, the task type and shooting area corresponding to the live broadcast task can be specified before the live broadcast starts, and the task type and shooting area corresponding to the live broadcast task can be obtained by parsing the live broadcast task; wherein, the task type may include interview tasks, dance tasks, etc., and the shooting area may be an interview area, a dance area, etc.

[0084] In one possible implementation, when determining the shooting area, the shooting area that matches the task type in the virtual scene can be determined based on the task type and the size of the scene area of ​​the real scene where the user of each virtual character controls the user; wherein the size of the shooting area matches the size of the scene area of ​​the real scene.

[0085] Here, the virtual character control user is a user who controls the virtual character in the virtual scene, and is used to output control information through the motion capture device worn by the user, and the control information is used to control the behavior of the corresponding target virtual character in the shooting area, thereby realizing the live broadcast of the virtual character in the virtual scene; the real scene is the scene in which the virtual character control user is active during the live broadcast, and the real scene can be the motion capture room where the virtual character control user is located, etc.

[0086] Specifically, when determining the shooting area that matches the task type in the virtual scene based on the task type and the size of the scene area of ​​the real scene where each virtual character controls the user, the task area division rule that matches the task type can be first determined based on the task type, and then the shooting area that matches the task type can be divided in the virtual scene based on the task area division rule; wherein the task area division rule may include a shooting area division ratio for characterizing the area ratio of the shooting area in the scene area of ​​the real scene, and a shooting area division method for characterizing the shooting area divided from the scene area of ​​the real scene.

[0087] Exemplarily, taking the task type of dance task as an example, the task area division rules matching the task type "dance task" may include a shooting area division ratio of "80%" used to characterize the area ratio of the shooting area in the scene area of ​​the real scene, and a shooting area division method for dividing the shooting area from the scene area of ​​the real scene "starting from the direction of the virtual camera corresponding to the dance task in the scene area of ​​the real scene, and the shape of the divided shooting area is a rectangle".

[0088] Following the above example, according to the task area division rule, a schematic diagram of dividing the shooting area matching the task type in the virtual scene can be as follows: Figure 2a and Figure 2b As shown, Figure 2a In the figure, the scene area of ​​the real scene where the virtual character controls the user is composed of the dark area and the white area in the figure. At this time, the virtual camera corresponding to the dance task is located on the left side of the figure, and the dark area representing the shooting area is also located on the left side of the figure. The dark area represents the shooting area divided according to the direction of the virtual camera corresponding to the dance task (the dark area in the figure is a rectangular area in the top view); Figure 2b In the figure, the scene area of ​​the real scene where the virtual character controls the user is composed of the dark area and the white area in the figure. At this time, the virtual camera corresponding to the dance task is located on the right side of the figure, and the dark area representing the shooting area is also located on the right side of the figure. The dark area represents the shooting area divided according to the direction of the virtual camera corresponding to the dance task (the dark area in the figure is a rectangular area in the top view).

[0089] In this way, when determining the shooting area corresponding to the live broadcast task, the area specified before the live broadcast starts can be used as the shooting area; or, the task area division rule matching the task type can be determined first, and then the shooting area is divided from the scene area corresponding to the real scene in real time according to the shooting posture of the virtual camera corresponding to the live broadcast task in the real scene and the task area division rule, and the size of the shooting area matches the scene area size of the real scene, so that the shooting area divided in real time can be more in line with the actual shooting situation in the real scene at the current moment, so that the virtual character controlling user can interact with the live broadcast more conveniently.

[0090] The selection process of the virtual camera group for S102:

[0091] Here, the virtual camera is a camera used to shoot virtual characters for live broadcast. The virtual camera can be a camera that exists in a virtual scene, or it can also be a camera that exists in a real scene. Different virtual cameras have different shooting attributes. The shooting attributes may include the shooting posture, shooting type, etc. of the virtual camera. The shooting type may include panoramic camera shooting with a fixed camera position, jib camera shooting that can be moved in multiple directions, track camera shooting that can be moved along a fixed track, close-up camera shooting with a fixed camera position, etc. Virtual cameras of different shooting types have different corresponding shooting functions and shooting effects. The control buttons corresponding to each virtual camera in the director device may be different. For example, virtual camera 1 corresponds to control button 1, virtual camera 2 corresponds to control button 2, and so on.

[0092] Wherein, when selecting a virtual camera group corresponding to the task type according to the task type, at least one of the following methods may be used:

[0093] Method 1: Select virtual cameras according to the task type to form a virtual camera group

[0094] In a possible implementation manner, when selecting a virtual camera according to a task type to form a virtual camera group, the following steps A1 to A2 may be performed:

[0095] A1: Determine a plurality of virtual cameras to be screened corresponding to the shooting area.

[0096] Here, when determining a plurality of virtual cameras to be screened corresponding to the shooting area, a plurality of virtual cameras to be screened that cover the shooting area within a corresponding shooting range can be determined from a virtual camera library corresponding to the real scene area.

[0097] A2: According to the task type, a virtual camera having a target shooting attribute is selected from the multiple virtual cameras to be screened to form a virtual camera group corresponding to the task type.

[0098] Here, the target shooting attributes may be shooting attributes corresponding to the task type. Taking the task type being a dance task as an example, the target shooting attributes corresponding to the dance task may be panoramic camera shooting, jib camera shooting that can move in multiple directions, track camera shooting that can move along a fixed track, close-up camera shooting with a fixed camera, and the like. By selecting a virtual camera with target shooting attributes corresponding to the dance task, a virtual camera group suitable for shooting the dance task can be selected.

[0099] Method 2: Select a virtual camera group from the multiple virtual camera groups to be screened according to the task type.

[0100] In a possible implementation manner, when selecting a virtual camera group from the plurality of virtual camera groups to be screened according to the task type, the following steps B1 to B2 may be performed:

[0101] B1: Determine a plurality of virtual camera groups to be screened corresponding to the shooting area.

[0102] Here, multiple groups of virtual camera groups to be screened may be preset for different shooting areas to meet different shooting requirements in the corresponding shooting areas.

[0103] Specifically, when determining the multiple groups of virtual camera groups to be screened corresponding to the shooting area, the multiple groups of virtual camera groups to be screened corresponding to the shooting area may be determined according to a preset mapping relationship between the shooting area and the virtual camera groups to be screened.

[0104] B2: According to the task type, a virtual camera group corresponding to the task type is selected from the multiple groups of virtual camera groups to be screened.

[0105] Here, the types of tasks to be screened corresponding to different virtual camera groups to be screened may be different. For example, the type of task to be screened corresponding to virtual camera group 1 to be screened may be slow-paced dance shooting, and the type of task to be screened corresponding to virtual camera group 2 to be screened may be fast-paced dance shooting.

[0106] Specifically, when selecting a virtual camera group corresponding to the task type from the multiple groups of virtual camera groups to be screened according to the task type, the virtual camera group corresponding to the task type to be screened in the multiple groups of virtual camera groups to be screened and matching the task type can be determined according to the task type and the task types to be screened respectively corresponding to the multiple groups of virtual camera groups to be screened.

[0107] In this way, by setting up corresponding multiple groups of camera groups to be screened according to the task requirements of different task types in the shooting area in advance, after determining the shooting area and task type, the virtual camera group corresponding to the task type can be selected from the multiple groups of virtual camera groups to be screened, thereby quickly completing the selection of the virtual camera and conducting live broadcast more quickly.

[0108] For S103,

[0109] Here, the camera movement trajectory may include a preset first camera movement trajectory, and / or a second camera movement trajectory controlled by a first user; different camera movement trajectories may use different virtual cameras, for example, the first camera movement trajectory may use a virtual camera whose shooting attribute is a track camera that moves along a fixed track, and the second camera movement trajectory may use a virtual camera whose shooting attribute is a jib camera that can move in multiple directions.

[0110] Among them, the preset first camera movement trajectory is the camera movement trajectory corresponding to the task type. For example, a preset first camera movement trajectory may correspond to a dance task, so that the shooting of the dance task can be completed through the first camera movement trajectory and the virtual camera; the first user may include a director controlling the user or a virtual character controlling the user, and the second camera movement trajectory controlled by the first user can achieve more flexible live shooting, thereby obtaining richer shooting effects.

[0111] In a possible implementation, when directing control is performed on each virtual camera in the virtual camera group according to the camera movement trajectory corresponding to the task type, in response to the fact that the preset first camera movement trajectories corresponding to the task type include multiple camera movement trajectories, a target first camera movement trajectory can be selected from the multiple first camera movement trajectories according to the camera movement modes and camera movement rates respectively corresponding to the multiple first camera movement trajectories, and the performance status information of each virtual character during the live broadcast, to perform directing control on each virtual camera in the virtual camera group.

[0112] Among them, the performance states of the virtual characters are different, and the corresponding camera movement methods and / or camera movement rates may be different. The performance states of the virtual characters may include fast-paced dance state, slow-paced dance state, interview state, etc.

[0113] In this way, by setting different camera movement methods and / or different camera movement rates for different performance states, the first camera movement trajectory that is more in line with the performance state of the virtual character can be selected during the director control stage of the live broadcast, thereby improving the live broadcast effect.

[0114] In another possible implementation, when director control is performed on each virtual camera in the virtual camera group according to the camera movement trajectory corresponding to the task type, during the process of director control of the virtual camera according to the first camera movement trajectory, in response to receiving the director control operation of the first user, the playback of the shooting image of the virtual camera corresponding to the second camera movement trajectory can be switched.

[0115] Here, the director control operation is used to switch the camera movement trajectory. By executing the director control operation, the camera movement trajectory can be converted from the current camera movement trajectory to the second camera movement trajectory.

[0116] In this way, by receiving the director control operation during the process of director controlling the virtual camera according to the first camera movement trajectory, the currently used preset first camera movement trajectory can be switched to the second camera movement trajectory controlled by the first user, so that the camera movement trajectory during the live broadcast process can be flexibly switched to meet different live broadcast requirements during the live broadcast process.

[0117] In one possible implementation, when switching to play the shooting picture of the virtual camera corresponding to the second camera movement trajectory, in response to an abnormality in the current output shooting picture of the first virtual camera corresponding to the first camera movement trajectory, the shooting picture of the second virtual camera can be switched to play according to the second virtual camera triggered by the first user.

[0118] Here, the abnormality of the currently output shooting picture may be that a virtual camera that generates the currently output shooting picture has a fault, and the fault may be, for example, that the virtual camera fails to generate a corresponding shooting picture according to a preset first camera movement trajectory; or, the abnormality of the currently output shooting picture may be that the virtual camera that generates the currently output shooting picture has a picture content that does not meet the picture content requirements.

[0119] In this way, if the virtual camera fails or the captured image content does not meet the image content requirements, the second virtual camera can be triggered in time according to the first user to switch to play the captured image of the second virtual camera, so that the live broadcast image content can be adjusted in time to ensure the normal progress of the live broadcast.

[0120] In another possible implementation manner, the following steps C1 to C2 may be used to switch and play the shooting picture of the virtual camera corresponding to the second camera movement track:

[0121] C1: In response to a shooting control operation of the virtual character controlling user on a handheld third virtual camera, target control information corresponding to the shooting control operation is determined.

[0122] C2: Control and display the shooting action corresponding to the target virtual character and the target control information, and switch to play the shooting picture of the third virtual camera.
