  • Patent number: 10650590
    Abstract: Methods and systems use a video sensor grid over an area, and extensive signal processing, to create a model-based view of reality. Grid-based synchronous capture, point cloud generation and refinement, morphology, polygonal tiling and surface representation, texture mapping, data compression, and system-level components for user-directed signal processing, is used to create, at user demand, a virtualized world, viewable from any location in an area, in any direction of gaze, at any time within an interval of capture. This data stream is transmitted for near-term network-based delivery, and 5G. Finally, that virtualized world, because it is inherently model-based, is integrated with augmentations (or deletions), creating a harmonized and photorealistic mix of real, and synthetic, worlds. This provides a fully immersive, mixed reality world, in which full interactivity, using gestures, is supported.

  • Patent number: 10621779
    Abstract: Artificial intelligence based techniques are used for analysis of 3D objects in conjunction with each other. A 3D model of two or more 3D objects is generated. Features of 3D objects are matched to develop a correspondence between the 3D objects. Two 3D objects are geometrically mapped and an object is overlayed on another 3D object to obtain a superimposed object. Match analysis of 3D objects is performed based on machine learning based models to determine how well the objects are spatially matched. The analysis of the objects is used in augmented reality applications.
