Omnidirectional catadioptric lens with odd aspheric contour or multi-lens

A generally conical element is defined about a vertical axis and having a tip on the vertical axis, and a generally conical odd aspheric contour mirror surface that is defined upward from the tip relative to the vertical axis. A toroidal lens element, disposed to capture light data input of a surrounding scene reflected from the odd aspheric contour mirror surface, has a cross-section shape defined relative to a plane passing through the toroidal lens element and including the vertical axis and is defined by revolving a convex or concave lens surface cross-section shape around the vertical axis, the convex or concave lens surface cross-section shape defined from another axis parallel to the vertical axis but offset, wherein the toroidal lens element cross-sectional shape is constant in rotation about the vertical axis and imparts a toroid shape to the toroidal lens element relative to the vertical axis.

Calibration Step for use in Connection with Method and System for Creating Wide-Screen Picture-Dominance Effect in a Conventional Motion-Picture Theater
20210227172 · 2021-07-22 ·

A calibration step is disclosed for use with a system and a method for creating a wide-screen picture-dominance effect in an auditorium located in a motion-picture theater. This is accomplished by an operator viewing a test image or images of horizontal and vertical lines projected onto a deeply-curved screen in said auditorium and adjusting the projection of said test image or images until the horizontal and vertical lines in said image or images appear straight and orthonormal, with the result that viewers watching motion pictures in said auditorium will observe images that appear wider than the physical confines of the auditorium in said theater.

Electronic device depth camera systems having a reduced number of outwardly-facing optical components are disclosed. Monocular depth camera systems, including basic depth camera systems as well as RGB-D camera systems, have exactly one window on a housing panel of the device through which light is transmittable out of and into the device housing. An optical emitter and detector(s) are located within the device housing. Binocular RGB-D camera systems have exactly two outwardly-facing optical components on the housing panel. One of the components, such as an optical emitter or an exit window, is associated with illumination light leaving the device, and the other optical component is an entrance window associated with transmitting detection light into the housing.

Method and apparatus for remapping pixel locations

An apparatus and method for optically remapping projected pixels to maximize the utilization and to optimize the distribution of remapped projection pixels to achieve optimal visual performance (generally uniform resolution and luminance). A device interposed between a projector and an imaging surface for optically remapping projected pixel locations with minimal aberration. When this device is interposed between a projector and an imaging surface, it changes the terminal location of each focused pixel such that it maximally coincides with the imaging surface, which is often a surface of complex curvature and very different from the native focal surface of the projector. One implementation of the technology includes a device that uses multiple optical surfaces.

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.

Panoramic stereoscopic imaging systems

An optical system for panoramic stereoscopic imaging can include an outer reflector and an inner reflector, which can both be configured to reflect light to a camera. The outer reflector can include striations or other reflection elements to turn the light that is reflected to the camera such that first and second light rays that are parallel and offset from each other (e.g., suitable for stereoscopic 3D viewing) can be reflected by the respective outer and inner reflectors to the camera. The outer reflector can be partially reflective and partially transmissive so that some light can pass through the outer reflector to be reflected by the inner reflector to the camera. The camera can capture a single image having a first portion that corresponds to a view generated by the inner reflector, and a second portion that corresponds to a stereoscopically offset view generated by the outer reflector.
