  • Patent number: 10885701
    Abstract: An augmented reality (AR) application allows for the specification of various lighting conditions, or lighting states, that can be simulated for an augmented reality view of a scene. This can include, for example, specifying a time of day to cause the view to be rendered with a specific amount of sunlight, or specifying a state of various light sources that can impact the illumination of the scene. A light map and lighting state data can be determined for the scene. A change to the lighting state data can result in a filter being applied to the live view of the scene to cause the overall appearance to correspond to the target lighting state. Augmented reality content displayed with respect to the live view can be rendered to have an appearance that corresponds to the altered live view. AR content can also be used to update the appearance of shadows.

  • Patent number: 10803665
    Abstract: Multiple devices executing an augmented reality (AR) application in a specific area can capture position data for objects in that area, which can be used to determine how to render the AR content. Since accuracy of this data falls off with distance, the data from the various devices can be collected by a dedicated server that can aggregate the position data to attempt to obtain a more accurate authoritative data set for the positions of objects and features in the area. At least relevant portions of the authoritative data set are transmitted back the individual devices such that the devices can use the more accurate data to render location- and scale-appropriate AR content over a live camera view captured by that device. Devices may receive data for the current field of view or other portions of the authoritative data set, as well as appropriate updates.

  • Patent number: 10777010
    Abstract: An environment map, such as a cube map, can be dynamically generated for a scene using image data captured by a device executing an augmented reality (AR) application. The current orientation of the device, along with field of view information for the camera, can be used to determine a portion of the environment map that corresponds to the captured image data. The image data can be used to fill in that portion, and subsequent image data captured for other orientations used to fill the remaining portions. The generated environment map can then be used to render AR content to be displayed with a live view of the scene. This can include determining the illumination and/or reflections effects for the AR content. The rendered AR content can be displayed as an overlay with respect to a live view of the scene.

  • Patent number: 10754418
    Abstract: Parts of the body of a user can be used as surfaces for rendering content, such as augmented reality (AR) content. A computing device executing an AR application can detect body parts in an augmented reality view, such as a hand within a field of view of a camera capturing image data for the application. A type of content to be displayed can be determined based on the type and orientation of the body part, in addition to the location and orientation of the device. The content can vary with changes in the orientation of the body part or motion to cause another body part to be visible. A user can make a selection or input for the content by contacting the surface of the body part onto which the content is projected, providing tactile feedback to the user as well as a determinable action for the device.

  • Patent number: 10607567
    Abstract: An environment map, such as a cube map, can be obtained for a scene that is appropriate for the current lighting state. A grayscale image representation is generated that represents physical objects visible in the scene. The grayscale representation is provided to a device for rendering AR content. A color lookup table (LUT) is generated for coloring the grayscale image representation. The color LUT can be appropriate for the current lighting conditions of the scene. As the lighting state changes, such as over the course of a day, different color LUTs can be sent to the device for purposes of updating the environment map. The grayscale image representation, once colored, can serve as an environment map for purposes of creating reflection effects on AR content to be rendered with respect to a live view of the scene.

  • Patent number: 10559121
    Abstract: Realistic reflections can be generated for augmented reality content displayed with respect to a view of a physical scene. A device executing an AR application obtains a three dimensional representation of the scene. The representation is used to determine surface orientation information for various physical objects in the physical scene, indicating how incident light would be reflected from those surfaces. The device can also use an infrared detector or transceiver to obtain an infrared view of the scene. The infrared data can be analyzed to determine the reflectivity of the various surfaces in the scene. Utilizing the surface orientation and reflectivity data, reflections from various AR content rendered for the scene can be determined. The corresponding pixels of the live view of the scene can then be color adjusted to account for the reflection, or an overlay can be generated that simulates the color adjustment for the reflection.
