摘要： An exemplary object identification system detects, based on a machine learning model, an object depicted within a video frame. The system identifies, based on the detecting of the object, a class label of the object and a region of interest, within the video frame, of the object. The system identifies, within the region of interest of the object, set of features of the object. The system compares the set of features of the object with a plurality of predefined features within a data store associated with the class label of the object. The system determines, based on the comparing of the set of features of the object with the plurality of predefined features within the data store, whether the object is configured to trigger an augmentation of video content associated with the video frame. Corresponding methods and systems are also disclosed.

摘要： An exemplary virtual reality system provides an experience selection data structure to a media player device. The experience selection data structure comprises a plurality of entries each corresponding to a different virtual reality dataset, and each virtual reality dataset is customized to a different virtual reality experience associated with a different virtual viewpoint positioned at a different location with respect to a three-dimensional (3D) scene. The virtual reality system detects that the media player device selects an entry from the plurality of entries by way of the experience selection data structure. The selected entry corresponds to a particular virtual reality dataset customized to a particular virtual reality experience. Thus, in response to the detecting, the virtual reality system provides the particular virtual reality dataset to the media player device. Corresponding methods and systems, including details regarding corresponding media player devices, are also disclosed.

摘要： An exemplary method includes a virtual reality content rendering system receiving two-dimensional (“2D”) color data and depth data captured by a plurality of capture devices disposed at different vantage points in relation to a three-dimensional (“3D”) scene, receiving metadata, generating, for each vantage point associated with each respective capture device included in the plurality of capture devices, and based on the metadata and the depth data, a partial 3D mesh projected into a virtual 3D space to produce a partial representation of the 3D scene in the virtual 3D space, and generating, based on the partial 3D meshes projected into the virtual 3D space, and from an arbitrary viewpoint within the virtual 3D space, an image view of the virtual 3D space. The generating of the image view may comprise accumulating the partial 3D meshes projected into the virtual 3D space.

摘要： An exemplary virtualized projection generation system receives a first frame sequence that includes frames depicting a real-world scene in accordance with a first set of capture parameters associated with a first view of the real-world scene. The virtualized projection generation system identifies a second set of capture parameters distinct from the first set of capture parameters and associated with a second view of the real-world scene distinct from the first view. Based on the first frame sequence, the virtualized projection generation system renders a second frame sequence that includes frames depicting the real-world scene in accordance with the second set of capture parameters associated with the second view of the real-world scene. Corresponding methods and systems are also disclosed.

摘要： An exemplary virtual reality system includes a management device, a synchronization device, and a gatekeeper device communicatively coupled to the management device and the synchronization device by way of a network. The gatekeeper device is configured to receive, at a particular time, a frame of a surface data frame sequence that the gatekeeper device is responsible for processing. The gatekeeper device is also configured to transmit, to the synchronization device, the particular time at which the gatekeeper device received the frame, and to receive, from the synchronization device, a timeframe during which the gatekeeper device is to transmit the frame. The gatekeeper device is further configured to transmit, to the management device during the timeframe received from the synchronization device, the frame of the surface data frame sequence. Corresponding systems and methods are also disclosed.

摘要： An exemplary virtual reality system accesses metadata describing a plurality of frame sequences that each include two-dimensional color data frames and depth data frames that depict a different view of a three-dimensional (3D) scene. The virtual reality system identifies a set of experience parameters defining a particular virtual reality experience associated with the 3D scene and that is to be experienced by a user using a media player device. Based on the metadata and the set of experience parameters, the virtual reality system selects frame sequences from the plurality of frame sequences for inclusion in a frame sequence subset that is customized to the particular virtual reality experience and that collectively includes data sufficient to allow the media player device to generate a virtual 3D representation of the 3D scene. The virtual reality system also provides the selected frame sequences of the frame sequence subset to the media player device.
