Many times I do my first optimization of yaw and pitch only, leaving roll=0, perhaps this could help you; further optimizations can/should consider roll, of course, but your values seen fine I did that. First only yaw for all except my position anchor image, then only pitch, then both yaw and pitch, then yaw, pitch and roll. Then I deselect yaw, pitch and roll when I optimize the other values, then deselect the other values and re-optimize yaw, pitch and roll, etc. HAHA! please, turn off the translations X, Y and Z, they should be used only for flat images, aka mosaics. Why? I thought they were for if I move the location of the camera between taking the pictures, which I indeed did (although not by very much in relation to the distance of what I took pictures of). Anyway, doing the whole optimization from scratch for the fourth time, now leaving x, y and z zeroed, seemed to have fixed it.

[hugin-ptx] 360 degree panorama *very* distorted
Hi, This is probably something simple, but I really can't figure out what I'm doing wrong. In hugin I have 15 images connected using 421 control points (mean error 0.2px, max 2.4). After the optimization the images range from yaw=-133.7 to yaw=173.4. That's ~307 degrees, but why not 360? 307 degrees is close, but now when I press Calculate Field of View on the Stitcher tab it gives 180x76 which is nowhere close to 360 degrees horizontally. The final image becomes extremely distorted. After changing the field of view to 360x80 the stiching produces this: https://lh3.googleusercontent.com/-kANvDRS4djc/UDFuiSY4NAI/ACY/ZHbUS-XaFcc/s1600/DienteDeInca_blended_fused.png This is supposed to be a landscape, but is so distorted you can't even see that. The image list looks like this: https://lh5.googleusercontent.com/-jPTWT3bvgHk/UDFuqXKOfUI/ACg/TYIq-RCOD9E/s1600/image-list.png Any ideas? -- You received this message because you are subscribed to the Google Groups Hugin and other free panoramic software group.

Re: [hugin-ptx] 360 degree panorama *very* distorted
Hi Marcus! Have you checked if the first and last images have control points linking them togheter? Once I had the same problem of not getting 360 deg field of view, in a row of pictures, using automatic control points. But I can´t recall my pano being so distorted as yours. Many times I do my first optimization of yaw and pitch only, leaving roll=0, perhaps this could help you; further optimizations can/should consider roll, of course, but your values seen fine HAHA! please, turn off the translations X, Y and Z, they should be used only for flat images, aka mosaics.

You might like to take a look at a related problem I had recently: http://www.lemis.com/grog/diary-aug2012.php?topics=p#D-20120813-000547 and http://.lemis.com/grog/diary-aug2012.php?topics=p#D-20120814-235244 (they're both on the same page, so you can just page down from the first). I don't mention it there, but these images were all taken with an 18 mm equivalent wide-angle lens spaced at 45 degrees. Greg -- Sent from my desktop computer.
