Patent number: 11368657Abstract: The present disclosure relates to a method for calibrating a projector. In one example, the method includes receiving by a processing element light field data corresponding to a calibration image projected by a projector and captured by a light field capturing device, and modeling by a processing element one or more intrinsic properties of the projector using the light field data and the calibration image. The calibration image may be projected by the projector directly into the light field capturing device.Type: GrantFiled: September 28, 2017Date of Patent: June 21, 2022Assignee: DISNEY ENTERPRISES, INC.Inventors: Anselm Grundhöfer, Daisuke Iwai

Patent number: 11170521Abstract: In an exemplary process for determining a position of an object in a computer-generated reality environment using an eye gaze, a user uses their eyes to interact with user interface objects displayed on an electronic device. A first direction of gaze is determined for a first eye of a user detected via the one or more cameras, and a second direction of gaze is determined for a second eye of the user detected via the one or more cameras. A convergence point of the first and second directions of gaze is determined, and a distance between a position of the user and a position of an object in the computer-generated reality environment is determined based on the convergence point. A task is performed based on the determined distance between the position of the user and the position of the object in the computer-generated reality environment.Type: GrantFiled: August 5, 2019Date of Patent: November 9, 2021Assignee: Apple Inc.Inventors: Mohamed Selim Ben Himane, Anselm Grundhöfer

Patent number: 11115633Abstract: The present disclosure relates to a method for calibrating a projector. The method includes projecting a test pattern onto a scene or an object within the scene and capturing the test pattern using a camera. Once the test pattern image has been captured by the camera, the method further includes estimating by a processing element a perspective projection matrix, warping the estimated projection matrix based on a non-linear distortion function, and modifying the projector to project light based on the distortion function. The present disclosure also relates to a presentation or projection system including two types of projectors for projecting an output presentation having a second image overlaid on a first image.Type: GrantFiled: August 9, 2018Date of Patent: September 7, 2021Assignee: DISNEY ENTERPRISES, INC.Inventor: Anselm Grundhöfer

Patent number: 9997134Abstract: Methods and systems for calibrating devices reproducing high dimensional data, such as calibrating High Dynamic Range (HDR) displays that reproduce chromatic data. Methods include mapping input data into calibrated data using calibration information retrieved from spatial data structures that encode a calibration function.
