Communication apparatus, communication method, and computer-readable storage medium
A communication apparatus for transmitting a virtual viewpoint video receives an acquisition request for a virtual viewpoint video, acquires viewpoint position information indicating a viewpoint position for the virtual viewpoint video from an apparatus that made the acquisition request, and transmits a virtual viewpoint video segment corresponding to the viewpoint position information to the apparatus that made the acquisition request. The virtual viewpoint video is video data in a format in which a video from any viewpoint position in a three-dimensional space can be rendered, and the virtual viewpoint video segment is generated by encoding the virtual viewpoint video as a two-dimensional video based on the viewpoint position information.
Video gateway for camera discovery and authentication
A video gateway device at a worksite (or other location) automatically locates cameras on the network, authenticates the gateway device with the cameras, and initiates streaming of a video stream (and/or other camera sensor data) from the cameras. For example, a worksite with existing cameras from multiple manufacturers, models, and/or capabilities may all be automatically registered with the video gateway devices through a series of automated communication and authentication attempts.
APPARATUS AND METHOD FOR EVALUATING A QUALITY OF IMAGE CAPTURE OF A SCENE
An apparatus for evaluating a quality for image capture comprises a stored (101) for storing a model of a scene and a capture circuit (105) for generating virtual captured images for a camera configuration by rendering from the model. A depth generation circuit (107) generates model depth data from the model and a depth estimation circuit (111) generates estimated depth data from the virtual captured images. A first synthesis circuit (109) and a second synthesis circuit (113) generates first and second view images for test poses by processing the virtual captured images based on the model depth data or estimated depth data respectively. A reference circuit (103) generates reference images for the f test poses by rendering based on the model. A quality circuit (115) generates a quality metric based on a comparison of the first view images, the second view images, and the reference images.
METHOD FOR ALLOCATING RESOURCES AND ELECTRONIC DEVICE
A method for allocating resources is provided. A server acquires resource allocation weights corresponding to a plurality of first user accounts in a virtual space, and generates a first resource quantity corresponding to each of the first user accounts by dividing a target resource quantity corresponding to the plurality of first user accounts, and allocates the resources of the target resource quantity to the plurality of first user accounts based on the first resource quantity corresponding to each of the first user accounts. The first user accounts are configured to publish live-streaming data into the virtual space for co-hosting.
INFORMATION PROCESSING APPARATUS, SYSTEM, INFORMATION PROCESSING METHOD, AND STORAGE MEDIUM
An information processing apparatus according to one embodiment of the present disclosure obtains image capturing information including information representing a position and an orientation of an image capturing device and movement information representing specific movement of the image capturing device; and generates viewpoint information representing a position of a virtual viewpoint and a view direction from the virtual viewpoint for generating a virtual viewpoint video based on the obtained image capturing information and the obtained movement information in a case where a captured image obtained by the image capturing device and the virtual viewpoint video generated based on a plurality of images are switched.
Method and device for transmitting information on three-dimensional content including multiple view points
Provided is a method for transmitting metadata for omnidirectional content including a plurality of viewpoints. The method comprises identifying the metadata for the omnidirectional content including the plurality of viewpoints; and transmitting the identified metadata, wherein the metadata includes information about an identifier (ID) of a viewpoint group including at least one viewpoint of the plurality of viewpoints, and wherein the at least one viewpoint in the viewpoint group shares a common reference coordinate system.
Information processing apparatus, information processing method, and program for point cloud sample processing
The present disclosure relates to an information processing apparatus and an information processing method that enable processing to be performed simply, and a program. By converting a point cloud representing a three-dimensional structure into two dimensions, a geometry image and a texture image, and three-dimensional information metadata required for constructing the geometry image and the texture image in three dimensions are obtained. Then, one PC sample included in a Point Cloud displayed at a specific time is generated by storing the geometry image, the texture image, and the three-dimensional information metadata in accordance with a playback order required at a time of reproducing and playing back the geometry image and the texture image in three dimensions on the basis of the three-dimensional information metadata. It is possible to apply to a data generation device that generates data for distribution of a Point Cloud.
Location-based application stream activation
A system and method enabling location-based activation of applications. The system comprises one or more servers storing and providing a persistent virtual world system including a virtual version of the real-world comprising one or more applications virtually attached to virtual-world entities positioned according to real-world coordinates, and being configured to compute the state of the virtual-world entities and to process the applications; send a minimum amount of application graphical representation to the user device responsive to receiving a notification of a user device accessing a trigger zone associated with the application(s); determine suitable application media streams to be sent to the user device responsive to receiving a notification of user interaction with the application graphical representation, perform heavy-load computational tasks on the media streams, and deliver the streams to the user devices, which perform lightweight computational tasks on the media content to output the media content.
Immersive Video Streaming Using View-Adaptive Prefetching and Buffer Control
A system obtains a data set representing immersive video content for display at a display time, including first data representing the content according to a first level of detail, and second data representing the content according to a second higher level of detail. During one or more first times prior to the display time, the system causes at least a portion of the first data to be stored in a buffer. During one or more second times prior to the display time, the system generates a prediction of a viewport for displaying the content to a user at the display time, identifies a portion of the second data corresponding to the prediction of the viewport, and causes the identified portion of the second data to be stored in the video buffer. At the display time, the system causes the content to be displayed to the user using the video buffer.
Navigating a virtual environment of a media content item
Systems and techniques are provided for switching between different modes of a media content item. A media content item may include a movie that has different modes, such as a cinematic mode and an interactive mode. For example, a movie may be presented in a cinematic mode that does not allow certain user interactions with the movie. The movie may be switched to an interactive mode during any point of the movie, allowing a viewer to interact with various aspects of the movie. The movie may be displayed using different formats and resolutions depending on which mode the movie is being presented.
