Publication number: 20240137664Abstract: An image sensor suitable for use in an augmented reality system to provide low latency image analysis with low power consumption. The augmented reality system can be compact, and may be small enough to be packaged within a wearable device such as a set of goggles or mounted on a frame resembling ordinary eyeglasses. The image sensor may receive information about a region of an imaging array associated with a movable object and selectively output imaging information for that region. The region may be updated dynamically as the image sensor and/or the object moves. Such an image sensor provides a small amount of data from which object information used in rendering an augmented reality scene can be developed. The amount of data may be further reduced by configuring the image sensor to output indications of pixels for which the measured intensity of incident light changes.Type: ApplicationFiled: January 3, 2024Publication date: April 25, 2024Applicant: Magic Leap, Inc.Inventors: Martin Georg Zahnert, Alexander Ilic, Erik Fonseka

Patent number: 11885871Abstract: An augmented reality device has a radar system that generates radar maps of locations of real world objects. An inertial measurement unit detects measurement values such as acceleration, gravitational force and inclination ranges. The values from the measurement unit drift over time. The radar maps are processed to determine fingerprints and the fingerprints are combined with the values from the measurement unit to store a pose estimate. Pose estimates at different times are compared to determine drift of the measurement unit. A measurement unit filter is adjusted to correct for the drift.Type: GrantFiled: May 24, 2019Date of Patent: January 30, 2024Assignee: Magic Leap, Inc.Inventors: Alexander Ilic, Martin Georg Zahnert, Koon Keong Shee

Patent number: 11809613Abstract: A high-resolution image sensor suitable for use in an augmented reality (AR) system to provide low latency image analysis with low power consumption. The AR system can be compact, and may be small enough to be packaged within a wearable device such as a set of goggles or mounted on a frame resembling ordinary eyeglasses. The image sensor may receive information about a region of an imaging array associated with a movable object, selectively output imaging information for that region, and synchronously output high-resolution image frames. The region may be updated dynamically as the image sensor and/or the object moves. The image sensor may output the high-resolution image frames less frequently than the region being updated when the image sensor and/or the object moves. Such an image sensor provides a small amount of data from which object information used in rendering an AR scene can be developed.Type: GrantFiled: October 30, 2019Date of Patent: November 7, 2023Assignee: Magic Leap, Inc.Inventors: Martin Georg Zahnert, Alexander Ilic

Patent number: 11798130Abstract: A smartphone may be freely moved in three dimensions as it captures a stream of images of an object. Multiple image frames may be captured in different orientations and distances from the object and combined into a composite image representing an image of the object. The image frames may be formed into the composite image based on representing features of each image frame as a set of points in a three dimensional point cloud. Inconsistencies between the image frames may be adjusted when projecting respective points in the point cloud into the composite image. Quality of the image frames may be improved by processing the image frames to correct errors. Reflections and shadows may be detected and removed. Further, optical character recognition may be applied. As the scan progresses, a direction for capturing subsequent image frames is provided to a user as a real-time feedback.Type: GrantFiled: August 30, 2021Date of Patent: October 24, 2023Assignee: Magic Leap, Inc.Inventor: Alexander Ilic

Patent number: 11631213Abstract: Forming a 3D representation of an object using a portable electronic device with a camera. A sequence of image frames, captured with the camera may be processed to generate 3D information about the object. This 3D information may be used to present a visual representation of the object as real-time feedback to a user, indicating confidence of 3D information for regions of the object. Feedback may be a composite image based on surfaces in a 3D model derived from the 3D information given visual characteristics derived from the image frames. The 3D information may be used in a number of ways, including as an input to a 3D printer or an input, representing, in whole or in part, an avatar for a game or other purposes. To enable processing to be performed on a portable device, a portion of the image frames may be selected for processing with higher resolution.Type: GrantFiled: December 30, 2016Date of Patent: April 18, 2023Assignee: Magic Leap, Inc.Inventors: Erik Fonseka, Alexander Ilic
