  • Patent number: 11989834
    Abstract: Devices and techniques are generally described for three dimensional room modeling. In various examples, 3D mesh data representing a room may be received. Plane data comprising a plurality of planes may be received. Each plane of the plurality of planes may represent a planar surface detected in the room. In some cases, a first plurality of wall candidates for a 3D model of the room may be determined based at least in part on the plane data. A second plurality of wall candidates for the 3D model of the room may be determined by modifying the first plurality of wall candidates based on a comparison of the first plurality of wall candidates to the 3D mesh data. The 3D model of the room may be generated based at least in part on the second plurality of wall candidates.

  • Patent number: 11922489
    Abstract: A camera is used to capture image data of representations of a physical environment. Planes and surfaces are determined from a representation. The planes and the surfaces are analyzed using relationships there between to obtain shapes and depth information for available spaces within the physical environment. Locations of the camera with respect to the physical environment are determined. The shapes and the depth information are analyzed using a trained neural network to determine items fitting the available spaces. A live camera view is overlaid with a selection from the items to provide an augmented reality (AR) view of the physical environment from an individual location of the locations. The AR view is enabled so that a user can port to a different location than the individual location by an input received to the AR view while the selection from the items remains anchored to the individual location.

  • Patent number: 11776211
    Abstract: Images of various views of objects can be captured. An object mesh structure can be created based at least in part on the object images. The object mesh structure represents the three-dimensional shape of the object. Alpha masks indicating which pixels are associated with the object can be used to refine the object mesh structure. A request can be made to view the object from an arbitrary viewpoint which differs from the viewpoints associated with the captured images. A subset of the captured images can be used to create a synthetic image. Different weights can be assigned to the captured image to render a synthetic image that represents the view from the arbitrary viewpoint selected. The input images for the synthetic image can be prefetched, or loaded into memory before the arbitrary view is requested. The images can also be cached for future use or to avoid reloading them for another synthetic image.

  • Publication number: 20220356754
    Abstract: The present invention provides a multi-directional opening flap pet door, relating to the technical field of pet bearing devices, which comprises: a supporting door frame, a bearing door frame, a locking seat and a blocking door panel. When a locking column slides into a bidirectional locking hole, the blocking door panel is locked bidirectionally, and when the locking column slides into an entrance-exit sliding hole, the blocking door panel is open bidirectionally. It solves the problem that most of the pet doors currently rotate in one direction, and the pet door needs to be adjusted manually, which limits the applicability of pet boxes or pet cages for pet bearing.

  • Publication number: 20220221976
    Abstract: A virtual vertical surface in a three-dimensional space that represents a physical room may be detected. Responsive to a first user input gesture, movement of a virtual object within the three-dimensional space may be displayed. The movement may be to a first location in which a portion of the virtual object intersects a portion of the virtual vertical surface. A virtual vertical surface designator may be displayed corresponding to the virtual vertical surface based at least in part on the portion of the virtual object intersecting the portion of the virtual vertical surface. Upon determining that a second user input gesture meets or exceeds a movement threshold, movement of the three-dimensional object from the first location to a second location within the three-dimensional space may be displayed. The second location may appear beyond the virtual vertical surface.

  • Patent number: 11093748
    Abstract: Various embodiments of the present disclosure provide systems and method for visual search and augmented reality, in which an onscreen body of visual markers overlayed on the interface signals the current state of an image recognition process. Specifically, the body of visual markers may take on a plurality of behaviors, in which a particular behavior is indicative of a particular state. Thus, the user can tell what the current state of the scanning process is by the behavior of the body of visual markers. The behavior of the body of visual markers may also indicate to the user recommended actions that can be taken to improve the scanning condition or otherwise facilitate the process. In various embodiments, as the scanning process goes from one state to another state, the onscreen body of visual markers may move or seamlessly transition from one behavior to another behavior, accordingly.

  • Publication number: 20210248798
    Abstract: Approaches in accordance with various embodiments provide for the presentation of augmented reality (AR) content with respect to optically challenging surfaces. Such surfaces can be difficult to locate using conventional optical-based approaches that rely on visible features. Embodiments can utilize the fact that horizontal surfaces can be located relatively easily, and can determine intersections or boundaries of those horizontal surfaces that likely indicate the presence of another surface, such as a vertical wall. This boundary can be determined automatically, through user input, or using a combination of such approaches. Once such an intersection is located, a virtual plane can be determined whose relative location to a device displaying AR content can be tracked and used as a reference for displaying AR content.
