  • Patent number: 9020529
    Abstract: In the field of mobile computing, a user of a mobile device takes a picture of a nearby landmark or building or street and transmits that picture via his device's wireless link to a remote server. The server has the capability of identifying the location from the photo by matching it against publicly available online collections of images, such as Flickr. The server executes a location identification algorithm to match the received photo to those in the collection to determine the actual location of the photo. Typically the images in the collections have metadata, such as textual tags. Upon identifying the most likely location of the received photo from the user, the server transmits back to the user's mobile computing device an indication of the location, such as a textual location description from the tag, a map or directions to a particular location. This is especially useful in a city or dense urban environment and where the mobile computing device does not have GPS capability or its GPS is inoperative.
