1. 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, each video frame having an array of image pixels, comprising:

  • determining a camera position of the digital video camera for each video frame;

    determining a smoothed camera path responsive to the camera positions;

    determining a sequence of target camera positions spaced out along the smoothed camera path such that video frames captured at the target camera positions have at least a target level of overlapping scene content;

    selecting a sequence of target video frames from the temporal sequence of video frames based on the target camera positions; and

    analyzing the target video frames using a three-dimensional reconstruction process to determine a three-dimensional model of the scene;

    wherein the method is implemented at least in part by a data processing system.
