Abstract:

© 1994, Springer Verlag. All rights reserved. The three-dimensional structure of a scene consisting of at least five points whose images are identified in two perspective views taken from different positions with a relative object-camera translation in between, can be reconstructed up to a 3D affine transformation. Hence, a more detailed reconstruction is possible using less information when compared to the results reported on arbitrary stereo views with uncalibrated, perspective cameras. The forementioned result is then further specialised towards single views of objects containing parallel structures and translations in camera coordinate planes. In the former case four points suffice for affine reconstruction, whereas the latter case allows the direct use of relatively simple stereo coordinates.
