Publication number: 20230281910Abstract: A background image is also generated, e.g., by filling portions of a captured image where a foreground object was extracted and communicated to the playback device, Foreground objects are identified and point cloud representations of the foreground objects are generated and communicated to a playback device so that they can be used in generating images including the background which is communicated separately. In the case of a point cloud representation a number of points in an environment, e.g., 3D space, are communicated to the playback device along with color information. Thus in some embodiments a foreground object is represented as a set of points with corresponding color information on a per point basis. Foreground object information is communicated and processed in some embodiments at a different rate, e.g., faster rate, then the background textures. The playback device renders images which are sent to the display by first rendering a background layer using the communicated background information, e.g.Type: ApplicationFiled: May 15, 2023Publication date: September 7, 2023Inventors: Hector Medina, David Cole, Alan Moss

Patent number: 11388384Abstract: Methods and apparatus for using selective resolution reduction on images to be transmitted and/or used by a playback device are described. Prior to transmission one or more images of an environment are captured. Based on image content, motion detection and/or user input a resolution reduction operation is selected and performed. The reduced resolution image is communicated to a playback device along with information indicating a UV map corresponding to the selected resolution allocation that should be used by the playback device for rendering the communicated image. By changing the resolution allocation used and which UV map is used by the playback device different resolution allocations can be made with respect to different portions of the environment while allowing the number of pixels in transmitted images to remain constant. The playback device renders the individual images with the UV map corresponding to the resolution allocation used to generate the individual images.Type: GrantFiled: July 17, 2018Date of Patent: July 12, 2022Assignee: Nevermind Capital LLCInventors: David Cole, Alan Moss, Hector Medina

Patent number: 11348252Abstract: Methods for capturing and generating information about objects in a 3D environment that can be used to support augmented reality or virtual reality playback operations in a data efficient manner are described. In various embodiments one or more frames including foreground objects are generated and transmitted with corresponding information that can be used to determine the location where the foreground objects are to be positioned relative to a background for one or more frame times are described. Data efficiency is achieved by specifying different locations for a foreground object for different frame times avoiding in some embodiments the need to transmit an image and depth information defining the same of the foreground for each frame time. The frames can be encoded using a video encoder even though some of the information communicated are not pixel values but alpha blending values, object position information, mesh distortion information, etc.Type: GrantFiled: July 15, 2019Date of Patent: May 31, 2022Assignee: Nevermind Capital LLCInventors: Alan Moss, Krishnaprasad Jagadash, Hector Medina, Fabricio Tofoli, Joel Phillips, Jun Liu, Ramesh Panchagnula, Vassilios Mavros

Publication number: 20200019045Abstract: Camera related methods and apparatus which are well suited for use in capturing stereoscopic image data, e.g., pairs of left and right eye images, are described. Various features relate to a camera rig which can be used to mount multiple cameras at the same time. In some embodiments the rig includes pairs of front, rear, upward and downward facing cameras, e.g., one or more camera pairs in each direction, arranged in a manner that allows each camera pair to capture a 180 degree view. In some embodiments a single side camera is used to capture left and right side images. The camera arrangement provides for a compact balanced camera rig which can be adjusted with regard to height from the ground and easily set up, e.g., using a tripod or other support structure including a support pole to which the camera are secured by one or more brackets and/or screws.Type: ApplicationFiled: July 12, 2019Publication date: January 16, 2020Inventor: Hector Medina

Patent number: 9865055Abstract: Camera and/or lens calibration information is generated as part of a calibration process in video systems including 3-dimensional (3D) immersive content systems. The calibration information can be used to correct for distortions associated with the source camera and/or lens. A calibration profile can include information sufficient to allow the system to correct for camera and/or lens distortion/variation. This can be accomplished by capturing a calibration image of a physical 3D object corresponding to the simulated 3D environment, and creating the calibration profile by processing the calibration image. The calibration profile can then be used to project the source content directly into the 3D viewing space while also accounting for distortion/variation, and without first translating into an intermediate space (e.g., a rectilinear space) to account for lens distortion.Type: GrantFiled: February 23, 2016Date of Patent: January 9, 2018Assignee: NextVR Inc.Inventors: David Michael Cole, Alan McKay Moss, Hector Medina

Patent number: 7704446Abstract: The present invention relates to an apparatus for injecting gas into a vessel. The apparatus may include a gas flow duct and a central body within a forward end region of the duct. The central body and the gas flow duct form an annular nozzle for the discharge of gas from the duct. A plurality of flow directing vanes are disposed about the central body to impart swirl to a gas flow through the nozzle. The flow directing vanes have substantially straight leading end portions radiating outwardly from the central body and extending along the duct. The vanes also have substantially helical trailing end portions extending helically about the central body toward the front end of the duct and transition portions joining the leading end portions to the trailing end portions. The transition portions are shaped so as to merge smoothly with both the leading end portions and the trailing end portions and to smoothly and progressively change shape between them.Type: GrantFiled: May 31, 2006Date of Patent: April 27, 2010Assignee: Technological Resources Pty.
