Abstract

An augmented reality display system comprises a passable world model data comprises a set of map points corresponding to one or more objects of the real world. The augmented reality system also comprises a processor to communicate with one or more individual augmented reality display systems to pass a portion of the passable world model data to the one or more individual augmented reality display systems, wherein the piece of the passable world model data is passed based at least in part on respective locations corresponding to the one or more individual augmented reality display systems.

Claims

1. An augmented reality system, comprising:

a first augmented reality display system corresponding to a first location, wherein the first individual augmented reality display system captures data pertaining to the first location;

a second augmented reality display system corresponding to a second location, wherein the second individual augmented reality display system captures data pertaining to the second location; and

a server comprising a processor to receive the captured data from the first individual augmented reality display system and the second individual augmented reality display system, and to construct at least a portion of a map of the real world comprising the first and second locations based at least in part on the received captured data from the first and the second individual augmented reality display systems.

2. The augmented reality system of claim 1, wherein the first augmented reality display system is a head-mounted augmented reality display system.

3. The augmented reality display system of claim 1, wherein the first augmented reality display system is a room-based sensor system.

4. The augmented reality display system of claim 1, wherein the constructed map is transmitted to at least one of the first and second augmented reality display systems.

5. The augmented reality display system of claim 4, wherein a virtual object is projected to at least one of the first and second augmented reality display systems based at least in part on the constructed map of the real world.

6. The augmented reality display system of claim 1, wherein the captured data is at least an image captured at the first or second location.

7. The augmented reality display system of claim 1, wherein the captured data corresponds to sensor data.

8. The augmented reality display system of claim 1, wherein the processor extracts a set of map points from the data captured from the first and second augmented reality display systems, and wherein the set of map points are used to construct the map of the real world.

9. The augmented reality display system of claim 1, wherein a part of the map corresponding to the first augmented reality display system is transmitted to the second augmented reality display system.

10. The augmented reality display system of claim 1, wherein the captured data comprises pose tagged images corresponding to the first location.

11. The augmented reality display system of claim 1, wherein the captured data comprises pose information of the first and second augmented reality display systems, wherein the map is constructed based at least in part on the pose information.
