  • Patent number: 10692234
    Abstract: Methods and apparatus for making environmental measurements are described. In some embodiments different devices are used to capture environmental information at different times, rates and/or resolutions. Environmental information, e.g., depth information, from multiples sources captured using a variety of devices is processed and combined. Some environmental information is captured during an event. Such information is combined, in some embodiments, with environmental information that was captured prior to the event. Environmental depth model is generated in some embodiments by combining, e.g., reconciling, depth information from at least two different sources including: i) depth information obtained from a static map, ii) depth information obtained from images captured by light field cameras, and iii) depth information obtained from images captured by stereoscopic camera pairs.

  • Publication number: 20200186779
    Abstract: 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.

  • Patent number: 10523920
    Abstract: Stereoscopic image processing methods and apparatus are described. Left and right eye images of a stereoscopic frame are examined to determine if one or more difference reduction operations designed to reduce the luminance and/or chrominance differences between the left and right frames is within a range used to trigger a difference reduction operation. A difference reduction operation may involve assigning portions of the left and right frames to different depth regions and/or other region categories. A decision on whether or not to perform a difference reduction operation is then performed on a per regions basis with at the difference between the left and right eye portions of at least one region being reduced when a difference reduction operation is to be performed. The difference reduction process may, and in some embodiments is, performed in a precoder which processes left and right eye images of stereoscopic frames prior to stereoscopic encoding.

  • Patent number: 10447994
    Abstract: 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 camera rig includes 3 mounting locations corresponding to 3 different directions 120 degrees apart. One or more of the mounting locations may be used at a given time. When a single camera pair is used the rig can be rotated to capture images corresponding to the locations where a camera pair is not mounted. Static images from those locations can then be combined with images corresponding to the forward direction to generate a 360 degree view. Alternatively camera pairs or individual cameras can be included in each of the mounting locations to capture video in multiple directions.

  • Publication number: 20190313075
    Abstract: An unobstructed image portion of a captured image from a first camera of a camera pair, e.g., a stereoscopic camera pair including fisheye lenses, is combined with a scaled extracted image portion generated from a captured image from a second camera in the camera pair. An unobstructed image portion of a captured image from the second camera of the camera pair is combined with a scaled extracted image portion generated from a captured image from the first camera in the camera pair. As part of the combining obstructed image portions which were obstructed by part of the adjacent camera are replaced in some embodiments. In some embodiments, the obstructions are due to adjacent fisheye lens. In various embodiments fish eye lenses which have been cut to be flat on one side are used for the left and right cameras with the spacing between the optical axis approximating the spacing between the optical axis of a human person's eyes.

  • Patent number: 10432910
    Abstract: Methods and apparatus for allowing a user to switch viewing positions and/or perspective while viewing an environment, e.g., as part of a 3D playback/viewing experience, are described. In various embodiments images of the environment are captured using cameras placed at multiple camera positions. During viewing a user can select which camera position he/she would like to experience the environment from. While experiencing the environment from the perspective of a first camera position the user may switch from the first to a second camera position by looking at the second position. A visual indication is provided to the user to indicate that the user can select the other camera position as his/her viewing position. If a user input indicates a desired viewing position change, a switch to the alternate viewing position is made and the user is presented with images captured from the perspective of the user selected alternative viewing position.

  • Patent number: 10412382
    Abstract: 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.

  • Patent number: 10397538
    Abstract: Methods and apparatus for supporting the capture of images of surfaces of an environment visible from a default viewing position and capturing images of surfaces not visible from the default viewing position, e.g., occluded surfaces, are described. Occluded and non-occluded image portions are packed into one or more frames and communicated to a playback device for use as textures which can be applied to a model of the environment where the images were captured. An environmental model includes a model of surfaces which are occluded from view from a default viewing position but which maybe viewed is the user shifts the user's viewing location. Occluded image content can be incorporated directly into a frame that also includes non-occluded image data or sent in frames of a separate, e.g., auxiliary content stream that is multiplexed with the main content stream which communicates image data corresponding to non-occluded environmental portions.

  • Patent number: 10397543
    Abstract: Methods and apparatus for streaming or playing back stereoscopic content are described. Camera dependent correction information is communicated to a playback device and applied in the playback device to compensate for distortions introduced by the lenses of individual cameras. By performing lens dependent distortion compensation in the playback device edges which might be lost if correction were performed prior to encoding are preserved. Distortion correction information maybe in the form of UV map correction information. The correction information may indicate changes to be made to information in a UV map, e.g., at rendering time, to compensate for distortions specific to an individual camera. Different sets of correction information maybe communicated and used for different cameras of a stereoscopic pair which provide images that are rendered using the same UV map. The communicated correction information is sometimes called a correction mesh since it is used to correct mesh related information.

  • Patent number: 10279925
    Abstract: A head mounted virtual reality (VR) device including an inertial measurement unit (IMU) is located in a vehicle which may be, and sometimes is, moving. Detected motion attributable to vehicle motion is filtered out based on one or more or all of: vehicle type information, information derived from sensors located in the vehicle external to the head mounted VR device, and/or captured images including a reference point or reference object within the vehicle. An image portion of a simulated VR environment is selected and presented to the user of the head mounted VR device based on the filtered motion information. Thus, the image portion presented to the user of the head mounted VR device is substantially unaffected by vehicle motion and corresponds to user induced head motion.
