摘要:We present GeoPilot, a system that combines photogrammetric techniques with GIS functionality to automate the identification of images. GeoPilot can be used to "tag" photos with keywords and location information to help users manage increasingly large photo collections and to retrieve information related to a photographed object on site, providing intuitive access to location-based information. The system consists of user-interface frontends for the photo management and location-based-service tasks that provide adapted access to the base functionality. Image identification is provided by feature detection and nearest neighbour search algorithms that match images against a reference database. The integration of Web 2.0 services allows to improve coverage of database and tagging information, e.g. by drawing on tagged images in on-line photo repositories like Flickr, while additional location information (e.g. GPS or GSM phone positioning) can be used to accelerate the matching process
