Linear features for photogrammetric restitution and object completion

Rigorous formulation in terms of only feature descriptors is given for: two- and three- dimensional transformations, photogrammetric conditions, and linear feature geometric constraints. Experimental results, considering control and pass features, from single photo resection (recovering both interior and exterior orientation elements) and two-photo triangulation (estimating pass lines for object completion), using simulated data and some real image data. Geometric constraints are used to provide redundancy in place of straight lines in stereo pairs. Extensive investigation is continuing.
