Patent ID: 8774527

Claim:
A computer-implemented method comprising: obtaining, using one or more computing devices, (i) an image of an object and (ii) one or more signal strength measurements that indicate a strength of a signal broadcast by a particular base station; determining a value that reflects a quantity of base stations in a vicinity of the particular base station; determining, using the one or more computing devices, an uncorrected location associated with the image based at least on the one or more signal strength measurements and the value that reflects the quantity of base stations in the vicinity of the particular base station; identifying, using the one or more computing devices, from among a collection of reference images that are each associated with a respective location, a set of reference images that are each associated with the uncorrected location associated with the image determined based at least on the one or more signal strength measurements and the value that reflects the quantity of base stations in the vicinity of the particular base station; identifying, using the one or more computing devices, a subset of the reference images that are classified as images of the object; and generating, using the one or more computing devices, a corrected location to associate with the image of the object based on the respective locations associated with the reference images of the subset.
