Abstract
A method for determining a three-dimensional model of a scene from a collection of digital images, wherein the collection includes a plurality of digital images captured from a variety of camera positions. A set of the digital images from the collection are selected, wherein each digital image contains overlapping scene content with at least one other digital image in the set of digital images, and wherein the set of digital images overlap to cover a contiguous portion of the scene. Pairs of digital images from the set of digital images to determine a camera position for each digital image. A set of target camera positions is determined to provide a set of target digital images having at least a target level of overlapping scene content. The target digital images are analyzed using a three-dimensional reconstruction process to determine a three-dimensional model of the scene.
