To reconstruct curved surfaces from uncalibrated cameras Kutulakos [7] exploited a purposive control of camera motions under the assumption of orthographic projections.
For perspective projection, Sato and Cipolla [12] showed that if the camera motions are unknown but pure translations and if the camera is uncalibrated but its internal parameters do not change under the camera motions, then the surfaces can be reconstructed up to an affine ambiguity. This result agrees with the case where fixed features are available [9].
