Abstract
Determining a location. An initial image is captured at an image capturing device. The initial image is compared with images in a database of images which have associated locations to determine the location of the image capturing device. A user receives a notification if a location cannot be determined.
Claims18
A method for determining a location, said method comprising:
- capturing an initial image of a scene at an image capturing device;
- uploading features of said initial image to a cloud server for comparing said features of said initial image to a database of features of images having associated locations to determine a location of said image capturing device;
- and
- provided said cloud server is unable to determine said location of said image capturing device based on said features of said initial image, receiving a notification from said cloud server wherein said notification comprises information to narrow a set of possible locations, wherein said notification comprises instructions for capturing a second image and indicating a second direction to capture said second image, wherein said instructions for capturing said second image comprises indicating an area to capture said second image, wherein said second image assists in determining said location, wherein said second direction dictates where said image capturing device should be moved to capture said second image to determine said location of said image capturing device, wherein said second direction is determined at least in part by a remote location determining service associated with said cloud server, wherein said area to capture said second image is determined based at least in part on said remote location determining service.

A method for providing a location to a device comprising:
- receiving features of an image from a device at a remote location determining service;
- comparing, at said remote location determining service, said features of said image to features of images within a database of features of images having locations associated with said features of images;
- and
- provided said location cannot be determined at said remote location determining service, sending a notification to said device from said remote location determining service wherein said notification comprises information to narrow a set of possible locations, wherein said notification comprises instructions for capturing a second image and indicating a second direction to capture said second image, wherein said instructions for capturing said second image comprises indicating an area to capture said second image, wherein said second image assists in determining said location, wherein said second direction dictates where said image capturing device should be moved to capture said second image to determine said location of said image capturing device, wherein said second direction is determined at least in part by a remote location determining service associated with a cloud server, wherein said area to capture said second image is determined based at least in part on said remote location determining service.
1 more element
A method for determining a location, said method comprising:
- capturing an initial image at an image capturing device;
- comparing said initial image to a database of features of images having locations associated with said images;
- provided said location cannot be determined after said comparing, capturing a second image at said image capturing device and comparing said second image to said database of features of images having locations associated with said images, wherein said second image is captured in a second direction indicated by a notification wherein said second direction dictates where said image capturing device should be moved to capture said second image to determine said location, wherein capturing said second image comprises indicating an area to capture said second image, wherein said second image assists in determining said location, wherein said second direction is determined at least in part by a remote location determining service associated with a cloud server, wherein said area to capture said second image is determined based at least in part on said remote location determining service;
- and
- determining said location.
