Abstract
A method for determining a three-dimensional model of a scene from a digital video captured using a digital video camera, the digital video including a temporal sequence of video frames. The method includes determining a camera position of the digital video camera for each video frame, and fitting a smoothed camera path to the camera positions. A sequence of target camera positions spaced out along the smoothed camera path is determined such that a corresponding set of target video frames has at least a target level of overlapping scene content. The target video frames are analyzed using a three-dimensional reconstruction process to determine a three-dimensional model of the scene.
