An information exchange method according to one or more embodiments of the present disclosure employs an extended reality (XR for short) technology. The extended reality technology can combine reality with virtuality through a computer to provide a user with a virtual reality space that allows for human-computer interaction. In the virtual reality space, the user may implement social interaction, entertainment, learning, working, telecommuting, creation of user generated content (UGC), etc., via the virtual reality device such as a head mount display (HMD).
The virtual reality device described in the embodiments of the present disclosure may include, but is not limited to, the following types:
Of course, an implementation form of the virtual reality device is not limited thereto, and the device may be further miniaturized or enlarged as needed.
A posture detection sensor (for example, a nine-axis sensor) is provided in the virtual reality device for detecting a posture change of the virtual reality device in real time. If the user wears the virtual reality device, a real-time posture of the head of the user is transmitted to a processor when a posture of the head changes, so as to calculate a fixation point of a line of sight of the user in a virtual environment, and calculate an image in a fixation range of the user (i.e., a virtual field of view) in a three-dimensional model of the virtual environment based on the fixation point. The image is displayed on a display screen, providing immersive experience that the user feels like watching in the real environment.
The virtual reality device, such as an HMD, is integrated with a number of cameras (for example, a depth camera, an RGB camera, etc.), which are not limited to providing pass-through views. A camera image and an integrated inertial measurement unit (IMU) provide data that may be processed by a computer vision method to automatically analyze and understand the environment. In addition, the HMD is designed to support not only passive computer vision analysis but also active computer vision analysis. In passive computer vision methods, image information captured from the environment is analyzed. The methods may be monoscopic (images from a single camera) or stereoscopic (images from two cameras). The methods include, but are not limited to, feature tracking, object recognition, and depth estimation. In active computer vision methods, information is added to the environment by projecting patterns that are visible to the camera but not necessarily visible to a human visual system. Such techniques include a time-of-flight (ToF) camera, laser scanning, or structured light to simplify the stereo matching problem. Active computer vision is used for implementing scene depth reconstruction.

Step S120: Receive composite video configuration information, where the composite video configuration information includes virtual reality space information, at least one piece of virtual reality subspace information corresponding to the virtual reality space information, and video configuration information corresponding to the virtual reality subspace information.
In some embodiments, the virtual reality space information is used to identify content presented by a virtual reality space. For example, taking a live video streaming as an example, the virtual reality space information may be a name of a live video streaming scene. For example, if a virtual live-streaming space is configured to live stream a program A, virtual reality space information corresponding to the virtual live-streaming space may be “the program A”.
In a specific implementation, a corresponding virtual reality space may be pre-configured at a server for video content to be played (e.g., the program A). The virtual reality space may have more than two virtual reality subspaces, each of which may be configured with one or more video streams. Videos displayed in different virtual reality subspaces may provide different video viewing angles for a same object (e.g., a same program), such as a stage-side viewing angle, a close-up viewing angle, and a long-shot viewing angle. After the configuration is completed, the server may deliver, to a client, virtual reality space information (such as a scene name and a scene ID) corresponding to the virtual reality space, information about a quantity of virtual reality subspaces that the virtual reality space has, and video configuration information corresponding to each virtual reality subspace.
In some embodiments, after the server delivers the composite video configuration information to the client, the client may convert the composite video configuration information to a preset standard format. In this embodiment, the client converts the received composite video configuration information to the preset standard format in a uniform manner, so that the client may be compatible with and adapted to composite video configuration information of different formats or versions.
In some embodiments, the video configuration information includes video presentation mode information, and the video presentation mode information includes one or more pieces of the following: screen shape information, screen quantity information, video dimension type information, and virtual camera information.
For example, the video presentation mode information may be used to describe a quantity of screens configured to present a video in the virtual reality subspace, a shape of each screen, a video dimension type (either a 3D video or a 2D video) corresponding to each screen, and the virtual camera information. The 3D video may include, but is not limited to, a rectangular 3D video, a semi-panoramic 3D video, a panoramic 3D video, or a fisheye 3D video. A virtual camera is a tool configured to simulate a viewing angle and a field of view at which a user can see in a virtual reality environment. The virtual camera information includes, but is not limited to, a focal length, an imaging angle, a spatial position, etc.
In some embodiments, the video configuration information includes video stream information. For example, coding formats such as H.265, H.264, and MPEG-4 may be used for a video stream.
In some embodiments, the virtual reality space may be a simulated environment of a real world, a semi-simulated and semi-fictional virtual scene, or a purely fictional virtual scene. The virtual scene may be any one of a two-dimensional virtual scene, a 2.5-dimensional virtual scene, or a three-dimensional virtual scene. A dimensionality of the virtual scene is not limited in this embodiment of this application. For example, the virtual scene may include sky, land, and sea, and the land may include environmental elements such as a desert and a city. The user may control a virtual object to move in the virtual scene.
Referring to
In an embodiment, the user may implement a related interactive operation in the virtual reality space via a controller, where the controller may be a gamepad. For example, the user may perform related operation control through an operation on a button of the gamepad. Of course, in another embodiment, a target object in a virtual reality device may be controlled by a gesture, speech, or multimodal control rather than a controller.
In some embodiments, the virtual reality space includes a virtual live-streaming space. In the virtual live-streaming space, a viewing user may control a virtual character (Avatar) to watch a live-streaming video of a performing user from a viewing angle such as a first-person view or a third-person view.
Step S140: Determine a target virtual reality subspace in which the user is located in the virtual reality space.
In some embodiments, the target virtual reality subspace in which the user is located in the virtual reality space is determined in response to an instruction triggered by the user to enable a virtual character controlled by the user to enter the target virtual reality subspace.
For example, the user may control the virtual character to move in the virtual reality subspace, and a preset instruction may be used to enable the virtual character controlled by the user to switch between different virtual reality subspaces.
In a specific implementation, a transfer point may be set in each virtual reality subspace. When the user controls the virtual character to approach or touch a transfer point, the virtual character is transferred into a target virtual reality subspace corresponding to the transfer point.
Step S160: Determine, based on the composite video configuration information, video configuration information corresponding to the target virtual reality subspace, and present video content in the target virtual reality subspace based on the determined video configuration information.
For example, when the user controls the virtual character to enter a virtual reality subspace B from a virtual reality subspace A, the client may perform video rendering based on pre-received video configuration information corresponding to the virtual reality subspace B, so as to present, to the user, video content provided in the virtual reality subspace B.
In some embodiments, a video presentation mode corresponding to the target virtual subspace, such as a quantity of screens, a shape of the screen, and a video dimension type (such as a 3D video or a 2D video) corresponding to the screen, may be determined based on the video configuration information corresponding to the target virtual subspace, to further create a corresponding screen and render a video in the target virtual subspace.
According to one or more embodiments of the present disclosure, the composite video configuration information is received, where the composite video configuration information includes the virtual reality space information, the at least one piece of virtual reality subspace information corresponding to the virtual reality space information, and the video configuration information corresponding to the virtual reality subspace information, so that the video configuration information corresponding to the target virtual reality subspace can be determined based on the received composite video configuration information, and the corresponding video content can be presented in the target virtual reality subspace. Therefore, a variety of video presentation scenes can be built on the client, providing rich and diverse viewing experience to the user.
In some embodiments, videos displayed in different virtual reality subspaces in a same virtual reality space may provide different video viewing angles, such as a stage-side viewing angle, a close-up viewing angle, and a long-shot viewing angle, for a same object (e.g., a same program).
For example, live streaming of a gala in the virtual reality space is used as an example for illustration. Referring to
In a specific implementation, video streams corresponding to different virtual reality subspaces can provide video content captured by camera apparatuses at different shooting angles or shooting positions.
In some embodiments, a same virtual reality subspace corresponds to two or more than two pieces of video configuration information. For example, one primary screen and a plurality of secondary screens may be set in one virtual reality subspace. The primary screen and the secondary screens may correspond to different video streams, different screen shapes, and different video dimension types. For example, a 3D panoramic video may be played on the primary screen, and a 2D video may be played on the secondary screens.
In some embodiments, primary screens in different virtual reality subspaces may be configured to present video content of different viewing angles, and secondary screens in different virtual reality subspaces may be configured to present video content of a same viewing angle.
In some embodiments, different video presentation environments may be presented in different virtual reality spaces, and the video presentation environment includes one or more of the following: a stage, setting, lighting, props, special effect elements, and choreography. For example, different video content, such as different program content, different live-streamers, and different galas, may be played through different virtual reality spaces, and different virtual reality spaces have different stage sets, lighting designs, animation special effects, etc.
In a specific implementation, different animation resources (such as a sticker, an animation model, and light and shadow special effects) for presenting video presentation environments may be configured for different virtual reality spaces. The animation resource may be pre-stored in the client for rendering a corresponding video presentation environment after the user enters a virtual reality space.
In some embodiments, the video configuration information includes live-streaming phase information, and the live-streaming phase information includes one or more of the following: a pre-live-streaming phase, an in-live-streaming phase, and a post-live-streaming phase. For example, different stage sets, lighting designs, and animation special effects may be presented in the virtual reality space in different live-streaming phases, providing rich viewing experience to the user.
Accordingly, according to an embodiment of the present disclosure, there is provided an information exchange apparatus, including:
In some embodiments, video configuration information corresponding to different virtual reality subspaces in a same virtual reality space is capable of providing different viewing angles for a same object.
In some embodiments, the viewing angle includes one or more of the following: a stage-side viewing angle, a close-up viewing angle, and a long-shot viewing angle.
