Patent number: 11677921Abstract: 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.Type: GrantFiled: January 2, 2022Date of Patent: June 13, 2023Assignee: DREAMVU INC.Inventors: Rajat Aggarwal, Anoop M Namboodiri, Parikshit Sakurikar

Patent number: 10154249Abstract: 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.Type: GrantFiled: June 19, 2017Date of Patent: December 11, 2018Inventors: Anoop M Namboodiri, Rajat Aggarwal, Amrisha Vohra
