PhotoTourism: ExploringPhotoCollectionsin3D 论文 Abstract Wepresentasystemforinteractivelybrowsingandexploringlarge unstructured collections of photographs of a scene using a novel 3D interface. Our system consists of an image-based modeling frontendthatautomaticallycomputestheviewpointofeachphotographaswellasasparse3Dmodelofthesceneandimagetomodel correspondences. Our photo explorer uses image-based rendering techniques tosmoothly transitionbetween photographs, whilealso enablingfull3Dnavigationandexplorationofthesetofimagesand worldgeometry,alongwithauxiliaryinformationsuchasoverhead maps. Our system also makes it easy to construct photo tours of scenic or historic locations, and to annotate image details, which are automatically transferred toother relevant images.
