It's something like 6 years I'm trying harder and harder to get the best results possible with panorama photography; by now I achieved significant improvements both in experience and equipment: thanks to a robotic pano head, now taking outside panorama is easy enough for me. However i'm rather disappointed that despite of all, when doing interiors, *my panoramas are still affected by small errors*. I did calibration of my lens, i carefully placed nodal point, i personally wrote the program that moves my robotic head, but i still have to optimize because the head has an angle uncertainty of something around 0.1-0.2 deg. When i use alignment through optimization of CPs, no matter how many point i have, there are lots of small errors (example with ~9000 http://www.stareat.it/viewers/pan0.swf?panoSrc=http://www.stareat.it/img/tropicalZooPano1.jpg&tesselation=100 )
I came to the conclusion that only two ways to overcome this, are 1. to buy a more precise robotic head and avoid alignment through optimization of CPs at all 2. to do small adjustment to alignment manually, somehow Given that i would happily avoid spending lots of money for a new head at the moment,* I'm pretty surprised that Hugin is so much behind if we speak of preview/manual alignment*. Now: I'm a professional developer and I have a couple ideas on how to use GPU for a nearly perfect realtime preview allowing us to do small adjustments by hand, but i'd need the exact same formula hugin uses to obtain consistent results. I now I could dig into Hugin sources (and i surely will) but i was wondering if someone more used to it could just point me/lay it down simple, to kickstart me. *E.g. : given a unit sphere and equirectangular projection, A and B being the yaw and pitch angle of a generic point Ps on its surface, Ya and Pi being yaw and pitch of center of an already corrected and placed image, X and Y being the generic point Pi on the image, what is the exact function that maps A, B to X, Y (taking into account all the other parameters i didn't mention, too...).* I mean: I'm not even sure Hugin does it always passing by equirectangular projection, but you got the point. In the meanwhile, if someone has other tips for me to better align my images, advices are more than welcome...
