While the homest package by Lourakis is a nice piece of work, I think that it would be better to stick with the physical model that panotools uses, as that also handle lens distortions properly and would allow using fisheye and cylindrical cameras, too. This would mean that one "just" needs to implement the right transformation functions, and reuse the exiting optimisation algorithms. The only problem is that all current panotools transformations have not been build with moving viewpoints in mind, so the panotools projections code would probably need some reorganisation/rewrite to allow this cleanly. Having a mode for properly mosaicing planar scenes would be an extremly welcome addition to hugin. ciao Pablo --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.
