Hello, It is 10+ years that I have last been active on this group,and on the panotools wiki as well. On the wiki my old credentials still work ;-)
In these old days I did detail that from the lens parameter set abc only the br^3 term is useful. Non-zero parameters a and c introduce singularities at r=0, something a real lens does not have. My query then was to also introduce r^5 and r^7 parameters. A few days ago I purchased a new camera in the form of the Parrot Anafi drone. The lens has some fisheye characteristics, similar to Gopro. I now discover that the available choice of lens types and parameters only allows bad alignment. It is not lens shift, it is not parallax error, it is that Barrel distortion by itself is not enough. Actually, switching on a and c parameters does make things worse :-( Where do you suggest should one further discuss this issue, where best to upload some panoramic source images?
