SPECTATOR VIEW OF VIRTUAL AND PHYSICAL OBJECTS
A user may interact and view virtual elements such as avatars and objects and/or real world elements in three-dimensional space in an augmented reality (AR) session. The system may allow one or more spectators to view from a stationary or dynamic camera a third person view of the users AR session. The third person view may be synchronized with the user view and the virtual elements of the user view may be composited onto the third person view.
1 . A method, performed by an augmented reality (AR) head-mounted display system having one or more hardware computer processors and one or more non-transitory computer readable storage devices storing software instructions executable by the AR head-mounted display system to:
access images of an environment obtained from an outward-facing camera of the AR head-mounted display system;
scan the images with reference to a camera;
determine a location with reference to a world coordinate system based on at least one of the images;
determine a camera origin point and gaze direction based at least partially on the location;
transmit the determined camera origin point and gaze direction to a computing system configured to:
render one or more virtual elements of the environment from the camera origin point and gaze direction;
composite the rendered one or more virtual elements and a video feed from the camera to generate a spectator view video feed of the environment; and
transmit the spectator view video feed to one or more display devices.
2 . The method of claim 1 , wherein the images are scanned for a known two-dimensional planar image at a fixed position with reference to a camera, and the location is determined based on the known two-dimensional planar image.
3 . The method of claim 2 , wherein the known two-dimensional planar image is associated with a lens of the camera.
4 . The method of claim 1 , wherein the AR head-mounted display system is further configured to: generate a virtual marker at the determined location.
5 . The method of claim 4 , wherein the AR head-mounted display system is further configured to: determine a camera origin point and gaze direction based at least partially on the virtual marker at the determined location.
6 . The method of claim 4 , wherein the virtual marker is a virtual cube or virtual box.
7 . The method of claim 4 , wherein the virtual marker comprises virtual particle animations.
8 . The method of claim 4 , wherein the virtual marker comprises virtual annotations.
9 . The method of claim 1 , wherein the camera is stationary.
10 . The method of claim 1 , wherein the one or more virtual elements comprise a virtual avatar.
11 . The method of claim 10 , wherein the virtual avatar interacts with a user of the AR head-mounted display system by at least one of a prearranged routine, an interactive interaction, or a puppeteer.
12 . The method of claim 1 , wherein the spectator view video feed comprises images of physical objects within a physical environment.
13 . The method of claim 12 , wherein the physical objects include a user of the AR head-mounted display system.
14 . The method of claim 1 , wherein the AR head-mounted display system is further configured to: transmit the video feed to one or more display devices.
15 . The method of claim 1 , wherein the AR head-mounted display system comprises a display system headset worn by a user.
16 . The method of claim 1 , wherein the computing system is a remote computing system.
17 . The method of claim 1 , wherein the camera is moveable.
18 . The method of claim 17 , wherein the computing system is configured to update the rendering of the one or more virtual elements as movements of the camera cause a perspective of the camera to update.
