The control points appear to be fine. It's the position of the images that is completely wrong. In this simple left-to-right set of images, the roll angles are detected as: 12.9 -173 167.2 -19.4 -0.7 13.9 Turns out there is a 10M per file limit preventing upload of an archive of all the pictures anyway. I've put them here temporarily: http://www.wonkity.com/~wblock/autopano-sift/ There's a readme.txt there also with steps to duplicate the problem. > I find it difficult to believe that this is a resource problem: do you > see any output on the command line that looks suspicious?

Tried adding --maxdim 4000 to the autopano-sift command line just now. It takes much longer to run, of course. The first (0/1) and last (4/5) pair of images are aligned with each other. #2 is upside down and misplaced, and #3 is just misplaced. > If the images are from a fish-eye or a ultrawide angle lens, have you > tried using the stereographic projection feature? Just a Canon SD950 point-and-shoot at its widest angle (36mm equiv). -Warren Block * Rapid City, South Dakota USA -- You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.
