  • Patent number: 11399141
    Abstract: An example holographic video recording system comprises: a first group of cameras positioned at a first position, a second group of cameras positioned at a second position, and a third group of cameras including a third infrared camera. The first group of cameras includes a first infrared camera and a first color camera; the second group of cameras includes a second infrared camera and a second color camera; and the third group of cameras includes a third infrared camera spatially positioned between the first and second infrared cameras. A depth map may be calculated using the first infrared camera and the second infrared camera in accordance with determining that an object is beyond a predefined distance from the holographic video recording system; or the first infrared camera and the third infrared camera in accordance with determining that the object is within the predefined distance from the holographic video recording system.

  • Patent number: 11398059
    Abstract: A mobile device comprises: a mesh loader manages configured to download compressed mesh sequences from a remote server into a local storage buffer; a mesh decoder that is configured to decode compressed mesh sequences into frames of meshes in real-time; a mesh decoder manager that is configured to request compressed mesh sequences from the mesh loader and to request the mesh decoder to decode the compressed mesh sequences; a player manager that is configured to decode texture video and to request corresponding decoded mesh from the mesh decoder manager and to maintain synchronizations between requesting the corresponding decoded mesh and decoding the texture video; and a renderer that is configured to render, using a rendering engine, the decoded mesh on a canvas; and a camera controller that is configured to detect one or more user actions and control a hardware camera in accordance with the one or more user actions.
