Tag configuration matcher for geo-tagging

Abstract

It is common today for even consumer-grade cameras to tag images and videos with the location of the imagery on the earth's surface. Some imagery, however, does not have a geo-location tag and it thus becomes necessary to ascertain the location of the camera, image, or objects in the scene. For such imagery, users must work hard to deduce geo-locations using reference data. Geo-tagging of such image/video is an extremely time-consuming and labor-intensive activity that often meets with limited success. In this paper, we propose a system to estimate the geo-location and viewing direction of a query photo using geometric configuration of objects in the query. Our experiment using a set of ground-truth data within our proposed system shows promising results.
