  • Publication number: 20240087150
    Abstract: Systems and methods are described for display of a depth image (depth plus texture) using multiple focal planes. In one embodiment, a depth image (which may be a frame of a depth video, consisting of a video plus depth sequence) is mapped to a first set of image planes. The depth image (or a subsequent frame of the depth video) is mapped to a second set of image planes. Each image plane in the first and second set has a specified depth, and the first and second set differ in at least one depth. Each of the image planes is displayed in the first set at the respective depth of that image plane, and, subsequently, each of the image planes in the second set is displayed at its respective depth. Display of the first and second sets may be cyclically alternated at rate sufficiently high to avoid perceptible flicker.

  • Publication number: 20230283762
    Abstract: Some embodiments of a method may include: identifying two-dimensional (2D) content present in an image of a real-world scene; retrieving metadata comprising depth information associated with the 2D content; generating a plurality of focal plane images using the metadata, the plurality of focal plane images comprising depth cues for the 2D content; and displaying the plurality of focal plane images as a see-through overlay synchronized with the 2D content.

  • Publication number: 20230027251
    Abstract: Some embodiments of an example method may include receiving an input image with depth information; mapping the input image to a set of focal plane images; orienting the set of focal plane images using head orientation information to provide stereo disparity between left and right eyes; and displaying the oriented set of focal plane images. Some embodiments of another example method may include: receiving a description of three-dimensional (3D) content; receiving, from a tracker, information indicating motion of a viewer relative to a real-world environment; responsive to receiving the information indicating motion of the viewer, synthesizing motion parallax by altering multi-focal planes of the 3D content; and rendering an image to the multi-focal plane display using the altered multi-focal plane rendering.

  • Patent number: 11488364
    Abstract: Augmented reality (AR) telepresence systems and methods are disclosed for obtaining a 3D model of a physical location from a 3D-capture system comprising one or more 3D depth sensors disposed throughout the physical location, generating a truncated 3D model of the physical location, the truncated 3D model corresponding to the intersection of the generated 3D model and a field of view of a user terminal camera at the physical location, and transmitting the truncated 3D model to a remote location.

  • Publication number: 20210235067
    Abstract: Methods and systems are described for capturing and displaying content for multiple focal plane (MFP) displays. In one example, a plurality of texture images of a scene are captured using a large-aperture camera, each texture image having a different focal distance. For each texture image, a focal plane image is generated. To generate the focal plane image, in some embodiments, each pixel in each texture image is multiplied by a respective weight value. The weight value may be based on a measured depth of the respective pixel (e.g. as determined using a captured depth map) and/or on a level of focus (or defocus) of the respective pixel as determined through filtering. The focal plane images may be displayed on a multi-focal-plane display and may be used to generate a virtual viewpoint.

  • Patent number: 10841537
    Abstract: Systems and methods described herein are provided for managing user positions in a shared virtual geometry, capturing 360° views of a local user environment in a spatially faithful system, and computing a perspective view of a first user from the eye-point of a second user. Users may move around the shared virtual geometry, and perspective views of users may be updated. Some embodiments use a co-centric geometry for group conferencing with other users. Some embodiments may use a grid-based geometry for exploration with other users. Some embodiments may reduce transferred bitrates to enable systems and methods to be implemented in data-limited environments. Some embodiments support users moving and navigating a shared virtual geometry.
