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.

Abstract translation: 在移动计算领域，移动设备的用户拍摄附近地标或建筑物或街道的照片，并通过他的设备的无线链路将该图片发送到远程服务器。 服务器能够通过将照片与公开可用的在线图像集合（如Flickr）进行匹配来识别照片的位置。 服务器执行位置识别算法以将接收到的照片与集合中的照片相匹配，以确定照片的实际位置。 通常，集合中的图像具有元数据，例如文本标签。 在从用户识别接收到的照片的最可能位置时，服务器向用户的移动计算设备发送该位置的指示，诸如来自标签的文本位置描述，地图或到特定位置的方向。 这在城市或密集的城市环境中特别有用，并且移动计算设备没有GPS能力或其GPS不起作用。
