I fully agree that this hFOV and vFOV nonsense should stop. It is really annoying for beginners and experienced folks alike!

The 'normalization' Helmut built into the radial polynomial, to keep one dimension of the image fixed, is not a good idea when dealing with lens correction. It mixes a linear scale factor -- analogous to focal length -- into what should properly be a dimensionless function. The practical effect is that the focal length computed by PanoTools depends on the image dimensions. But it is absurd to think that putting a different sensor behind a lens can change its focal length. -- You received this message because you are subscribed to the Google Groups "Hugin and other free panoramic software" group.
