  • Patent number: 11875537
    Abstract: A system for registering one or more cameras and/or creating an accurate three-dimensional (3D) model of a world space environment including back projecting at least one image from at least one of a plurality of camera views to the 3D model based on a set of existing camera parameters. The back projected image is added as a texture for the 3D model. This texture is automatically compared to one or more images from other camera views using a color space comparison of images to determine a set of differences or errors. The camera parameters and the 3D model are automatically adjusted to minimized the differences or errors. Over time, the parameters and the 3D model converge on a state that can be used to track moving objects, insert virtual graphics and/or perform other functions.

  • Patent number: 11870967
    Abstract: Methods and apparatus for supporting the capture of images of surfaces of an environment visible from a default viewing position and capturing images of surfaces not visible from the default viewing position, e.g., occluded surfaces, are described. Occluded and non-occluded image portions are packed into one or more frames and communicated to a playback device for use as textures which can be applied to a model of the environment where the images were captured. An environmental model includes a model of surfaces which are occluded from view from a default viewing position but which maybe viewed is the user shifts the user's viewing location. Occluded image content can be incorporated directly into a frame that also includes non-occluded image data or sent in frames of a separate, e.g., auxiliary content stream that is multiplexed with the main content stream which communicates image data corresponding to non-occluded environmental portions.

  • Patent number: 11863902
    Abstract: Responsive to a zoom command when presenting a first video, a second video is combined with the first video and presented. The first and second videos are generated from substantially the same camera location as each other at substantially the same time with substantially the same resolution. However, the second video is generated by a physical or virtual lens having a field of view (FOV) smaller than the FOV of a physical or virtual lens used in generating the first video. The technique gives the appearance of zooming without loss of resolution.

  • Patent number: 11799936
    Abstract: A vehicle remote support system includes a communication system that operates over a plurality of parallel wireless network connections to provide low-latency video from vehicle to a remote support server that provides remote support to the vehicle dependent on real-time video. The vehicle includes a source that encodes multiple versions of the original video segments (e.g., one per wireless network connection) and transmits the multiple versions of the segments to a sink at the remote support server over the respective wireless connections. This redundant multi-path communication system rationally allocates network resources to the managed video streams and balances bandwidth against latency in order to avoid network congestion and safety issues associated with single-path transmissions. In other embodiments, a similar communication system that transmits video or other real-time messages between a source and a sink may be utilized in cloud robotics applications.
