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.

System and method for generating dewarped image using projection patterns captured from omni-directional stereo cameras

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.

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.

A system for capturing horizontal disparity stereo panorama is disclosed. The system includes a multi surface selective light reflector unit, a secondary reflector and a computing unit. The multi surface selective light reflector unit (a) obtains light rays from a 3D scene of outside world that are relevant to create (i) a left eye panorama and (ii) a right eye panorama and (b) reflects the light rays without internal reflections between the light rays. The secondary reflector (a) obtains the reflected light rays from the multi surface selective light reflector unit and (b) reflects the light rays through the viewing aperture. The computing unit captures (i) the reflected light rays from the secondary reflector and (ii) the upper part of the 3D scene from a concave lens as a warped image and processes the warped image to (a) the left eye panorama and (b) the right eye panorama.
