determining whether objects recognized from the area are transient in the area;

associating the objects recognized from the area with metadata related to whether the objects are transient in the area; and

based on determining that at least a first object from the area is not transient, including a representation of the first object in the 3D model, the determining that the first object is not transient being based at least in part on identifying a first object type for the first object;

wherein the determining that the first object from the area is not transient is performed at least in part by processing metadata associated with the first object type from a database that associates respective object types with metadata related to whether objects of the respective object type are transient.

8. The method of claim 7 , wherein the method comprises:

responsive to receiving input from a user to show, in the 3D model, representations of objects from the area that are transient, including in the 3D model representations of objects from the area that are transient and presenting the 3D model on a display.

9. The method of claim 7 , wherein the method comprises:

responsive to receiving input from a user to not show, in the 3D model, representations of objects from the area that are transient, presenting the 3D model on a display without showing representations of objects from the area that are transient.

10. The method of claim 7 , comprising:

based on determining that at least a second object from the area is transient, declining to include a representation of the second object in the 3D model.

11. The method of claim 10 , comprising:

determining that the second object from the area is transient at least in part by processing metadata from a database that associates respective object types with metadata related to whether objects of the respective object type are transient.

12. The device of claim 1 , wherein the at least one the object is associated with time-related metadata based on a comparison of images that are generated at different times.

13. The device of claim 1 , wherein the establishing of the 3D model and the associating of the at least one object is performed responsive to receipt of user input directed to a selector presented on a user interface (UI), the UI presented on a display.

14. The method of claim 7 , wherein the generating of the 3D model and the associating of the objects is performed responsive to receipt of user input directed to a selector presented on a user interface (UI), the UI presented on a display.

15. A device, comprising:

at least one computer readable storage medium that is not a transitory signal, the computer readable storage medium comprising instructions executable by at least one processor to:

generate a three-dimensional (3D) model of an area;

determine whether objects recognized from the area are transient in the area;

associate the objects recognized from the area with metadata related to whether the objects are transient in the area; and

based on determining that at least a first object from the area is not transient, include a representation of the first object in the 3D model, the determining that the first object is not transient being based at least in part on identifying a first object type for the first object;

wherein the determining that the first object from the area is not transient is performed at least in part by processing metadata associated with the first object type from a database that associates respective object types with metadata related to whether objects of the respective object type are transient.

16. The device of claim 15 , comprising the at least one processor.

17. The device of claim 16 , comprising a camera accessible to the at least one processor, wherein the 3D model of the area is generated based at least in part on at least one image from the camera.

18. The device of claim 15 , wherein the instructions are executable to:

responsive to receipt of input from a user to show, in the 3D model, representations of objects from the area that are transient, include in the 3D model representations of objects from the area that are transient and present the 3D model on a display.

19. A method, comprising:

receiving at least one image from a camera;

based at least in part on the at least one image from the camera, establishing a three-dimensional (3D) model of at least a portion of a location shown in the at least one image, the 3D model being different from the location itself that is shown in the at least one image;

identifying at least a first object shown in the at least one image from the camera; and

associating the first object shown in the at least one image with time-related metadata;

wherein the time-related metadata comprises metadata regarding the permanence of the first object; and
