  • Patent number: 11677921
    Abstract: A system for generating high-resolution de-warped omni-directional stereo image from captured omni-directional stereo image by correcting optical distortions using projection patterns is provided. The system includes a projection pattern capturing arrangement, a projector or a display, and a de-warping server. The projection pattern capturing arrangement includes one or more omnidirectional cameras to capture projection patterns from the captured omni-directional stereo image from each omni-directional stereo camera. The projector or the display displays the projection patterns. The de-warping server obtain the projection patterns and processes the projection patterns to generate high resolution de-warped omni-directional stereo image by correcting optical distortions in the captured omni-directional stereo image and mapping the captured omni-directional stereo image and the high resolution de-warped omni-directional stereo image.

  • Patent number: 11523101
    Abstract: A method of calibrating cameras used to collect images to form an omni-stereo image is disclosed. The method may comprise determining intrinsic and extrinsic camera parameters for each of a plurality of left eye cameras and right eye cameras arranged along a viewing circle or ellipse and angled tangentially with respect to the viewing circle or ellipse; categorizing left-right pairs of the plurality of left eye cameras and the plurality of right eye cameras into at least a first category, a second category or a third category; aligning the left-right pairs of cameras that fall into the first category; aligning the left-right pairs of cameras that fall into the second category; and aligning the left-right pairs of cameras that fall into the third category by using extrinsic parameters of the left-right pairs that fall into the first category, and of the left-right pairs that fall into the second category.

  • Patent number: 11025888
    Abstract: A system for capturing Omni-Stereo videos using multi-sensor includes left cameras, right cameras and a viewing circle. A method of capturing omni stereo videos using multi-sensor approach includes steps of: capturing images of a scene using left cameras, capturing images of a scene using right cameras, processing each image from the left camera and right camera using a computation method, and obtaining a final omni stereo frame through the computation method.
