Abstract
The velocities of points in an image taken by a moving camera depend on the motion of the camera relative to the environment and on the distances to the object points from which they arise. It is these dependencies that allow the reconstruction of the camera velocity and the shape of the scene from the image velocities. If the full camera calibration is known then reconstruction yields the angular velocity of the camera, the direction of the translational velocity and the shape of the scene up to a single unknown scale factor. Reconstruction from image velocities is a limiting case of reconstruction from image correspondences, as the distances between corresponding points become small. In the limit the underlying equations are simplified, but many of the properties of reconstruction from image correspondences are retained, most notably in the ambiguous case.
