PAPER ABSTRACTS

Photographing Long Scenes with Multi-Viewpoint Panoramas

We present a system for producing multi-viewpoint panoramas of long, roughly planar scenes, such as the facades of buildings along a city street, from a relatively sparse set of photographs captured with a handheld still camera that is moved along the scene.

Our work is a significant departure from previous methods for creating multiviewpoint panoramas, which composite thin vertical strips from a video sequence captured by a translating video camera, in that the resulting panoramas are composed of relatively large regions of ordinary perspective. In our system, the only user input required beyond capturing the photographs themselves is to identify the dominant plane of the photographed scene; our system then computes a panorama automatically using Markov Random Field optimization.

Users may exert additional control over the appearance of the result by drawing rough strokes that indicate various high-level goals. We demonstrate the results of our system on several scenes, including urban streets, a river bank, and a grocery store aisle.

Photo Tourism: Exploring Photo Collections in 3D

We present a system for interactively browsing and exploring a large unstructured collection of photographs of a scene using a novel 3D interface. Our system consists of an image-based modeling front end, which automatically computes the viewpoint of each photograph as well as a sparse 3D model of the scene and image to model correspondences.

Our photo navigation tool uses imagebased 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, as well as to annotate image details, which are automatically transferred to other relevant images in the collection. We demonstrate our system on several large personal photo collections as well as images gathered from photo sharing Web sites on the Internet.
