Image-based geo-hunt

摘要

During a communication technique, an image and information specifying a location of an electronic device when the image was captured are received. Then, a reference image, associated with a second location (which is at least proximate to the location), in a predefined set of one or more reference images is accessed. These predefined set of one or more reference images are associated with a set of one or more locations along a geographic route that includes the second location. Moreover, the image is compared to the reference image. If the comparison indicates a match between the image and the reference image, a message is provided indicating that a milestone in navigating the geographic route has been achieved. Otherwise, a second message is provided indicating that the milestone in navigating the geographic route has not been achieved.

主权项

1. A computer-implemented method for providing feedback, the method comprising:
receiving an image and information specifying a location of an electronic device when the image was captured; accessing a reference image, associated with a second location, in a predefined set of one or more reference images stored in a computer-readable memory based on the location, wherein the predefined set of one or more reference images are associated with a set of one or more locations along a geographic route that includes the second location, and wherein the location is at least proximate to the second location; using the computer, comparing the image to the reference image; if the comparison indicates a match between the image and the reference image, providing a message indicating that a milestone in navigating the geographic route has been achieved; and otherwise, providing a second message indicating that the milestone in navigating the geographic route has not been achieved.
