Abstract (AI)
We present a system for interactively browsing and exploring large unstructured collections of photographs of a scene using a novel 3D interface. Our system consists of an image-based modeling front end that automatically computes the viewpoint of each photograph as well as a sparse 3D model of the scene and image to model correspondences. Our photo explorer uses image-based rendering techniques to smoothly transition between photographs, while also enabling full 3D navigation and exploration of the set of images and world geometry, along with auxiliary information such as overhead 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 to other relevant images. We demonstrate our system on several large personal photo collections as well as images gathered from Internet photo sharing sites.
Key Findings
1
A system was developed for interactively browsing large unstructured photo collections using a novel 3D interface.
2
An image-based modeling front end automatically computes each photograph's viewpoint, a sparse 3D scene model, and image-to-model correspondences.
3
Auxiliary information such as overhead maps can be integrated into the exploration interface.
4
The approach is demonstrated on several large personal photo collections and images gathered from Internet photo sharing sites.
5
The photo explorer uses image-based rendering to smoothly transition between photographs while enabling full 3D navigation and exploration of images and scene geometry.
6
The system supports easy construction of photo tours and annotation of image details, with annotations automatically transferred to other relevant images.
