Abstract

A system, method, and device for creating an environment and sharing an experience using a plurality of mobile devices having a conventional camera and a depth camera employed near a point of interest. In one form, random crowdsourced images, depth information, and associated metadata are captured near said point of interest. Preferably, the images include depth camera information. A wireless network communicates with the mobile devices to accept the images, depth information, and metadata to build and store a 3D model of the point of interest. Users connect to this experience platform to view the 3D model from a user selected location and orientation and to participate in experiences with, for example, a social network.

Claims

1. A system for creating and sharing an environment comprising:

a network for receiving metadata including range metadata from one or more devices each having a depth camera employed near a point of interest to capture associated metadata near said point of interest, wherein the associated metadata includes a location of the device, an orientation of the camera and range between the depth camera and one or more targets near said point of interest;

an image processing server connected to the network for receiving said metadata including range metadata, wherein the server processes the metadata including range metadata to determine the location of said one or more targets to build a 3D model of said one or more targets proximate the point of interest based at least in part on said range metadata;

an experience platform connected to the image processing server for storing the 3D model of one or more targets, whereby users can connect to the experience platform to view the point of interest from a user selected location and orientation, and view the 3D model of one or more targets.

2. The system of claim 1 wherein the network includes wireless access and some of the devices are mobile, wherein random images and metadata including range are crowdsourced and acquired at random from users of the mobile devices.

3. The system of claim 2, wherein said images include advertising based on context.

4. The system of claim 1, wherein the experience platform includes a plurality of images associated with locations near the point of interest and a user connected to the experience platform can view images associated with a user selected location and orientation.

5. The system of claim 1, wherein the processing server is operable to stitch a number of images together to form a panorama.

6. The system of claim 5, wherein a user connected to the experience platform can view panoramas associated with a user selected location and orientation.

7. A method for creating an environment for use with a location based experience, comprising:

capturing a plurality of images comprising associated metadata near a point of interest with a plurality of mobile devices accompanying a number of contributors, each mobile device having a depth camera, wherein the associated metadata for said image includes a location of the mobile device, an orientation of the camera, and range between the depth camera and one or more targets near said point of interest;

communicating said metadata from said mobile devices to a wireless network;

receiving said metadata including range metadata at an image processing server connected to the network; and

processing the metadata including range metadata to determine the location of one or more targets in the images and to build a 3D model of one or more targets near the point of interest, using the range between the depth camera and one or more targets near said point of interest.

8. The method of claim 7, the depth camera comprising a time of flight camera, a structured light sensor, a plenoptic camera or stereo triangulation cameras.

9. The method of claim 7, wherein said processing step includes using an existing 3D model of a target and enhancing said existing 3D model using said captured images and metadata.

10. The method of claim 7, wherein said images are crowdsourced from a plurality of contributors and acquired at random without coordination among said users.

11. A portable device for assisting in capturing 3D information near a point of interest, comprising:

a conventional optical camera for capturing an image of the point of interest;

a depth camera for capturing range metadata comprising the range between the depth camera and one or more targets near said point of interest and excluding depth of field,

 

said depth camera using one or more of the following sensors—

sheet of light, structured light, time of flight, interferometry, coded aperture, LIDAR, light field or stereo triangulation;

memory for storing metadata associated with said image or range metadata or both;

a communication link to an experience server, operable to load information relevant to the point of interest to the device, operable to transmit said range metadata to build a 3D model proximate the point of interest and to download at least a portion of said 3D model proximate the point of interest; and

a display operable to view a perspective view of said 3D model of said point of interest from said device position proximate said point of interest, said display operable to show at least some of said load information as an artificial reality (“

AR”

) message.

12. The device of claim 11, wherein said portable device comprises glasses that include a transparent display operable to view at least a portion of said point of interest and to view said artificial reality message.

13. The device of claim 11, wherein said display includes goggles wearable by a user to view a point of interest with at least some portion of the point of interest enhanced with artificial reality.

14. The device of claim 11, the depth camera including light field range metadata between the depth camera and a plurality of targets near said point of interest.

15. The device of claim 14, the display operable to view at least a portion of said 3D model including light field range metadata.

16. A method of sharing content in a location based experience, comprising:

capturing a plurality of images and associated metadata near a point of interest, including range metadata comprising range between a depth camera and a target in an image;

processing the captured images, range, and associated metadata to build a 3D model of one or more targets near said point of interest;

storing the 3D model of one or more targets in an experience platform connected to a network;

accessing the experience platform using the network to access the 3D model of one or more targets;

and

viewing the 3D model of one or more targets using glasses wearable by a user.

17. The method of claim 16, including viewing the 3D model of one or more targets and an advertisement based on context.

18. The method of claim 16, wherein said images are captured by crowdsource from users equipped with mobile devices and acquired at random without coordination of targets or lime of acquisition among users.

19. The method of claim 18, wherein at least one of the mobile devices includes a depth camera comprising a time of flight camera, a structured light sensor, a plenoptic camera, or a stereo triangulation camera and said range excluding depth of field.

20. The method of claim 16, wherein said processing step includes receiving an existing 3D model of a target and enhancing said preexisting 3D model using said captured images and range metadata acquired at random.

21. The method of claim 16, wherein said viewing step includes a user remote from said selected location.
