You could try dealing with the groups that actually connect separately and merge the panos after. Just save under a different name and throw out the 'other ' bunch. And if you then manually connect just two images, one from the first and one from the second bunch, it should all snap into place so well that you can take it from there. But you may want to reset all image positions first then and start with a fresh optimize from anchor. Don't be too attached to any positionings you may already have. > I bet I don't have keyfiles since I didn't know I needed those! How > do I generate those?

Keyfiles are a bit of a thing from the past. They have to do with the way how control points are found. First, all images are scanned for 'feature points', which have certain mathematical properties that make it likely that they can be recognized in another image. These feature points, or key points, can be stored in a file, one file per image is made. These keyfiles ar then put into a matching algorithm to look for the best candidtates (those which very high correspondence of the feature vectors) - after a bit of cleaning up these become the control points. Nowadays, where memory is cheap, the writing-to-disc of keyfiles is usually omitted, but some programs can still do it. If cpfind, for example, is called with -k, it will produce keyfiles. The approach has a certain appeal, because the feature vectors can be calculated once for each image, and in subsequent matchings they can be reused. It is used today when the matching pattern suggests that the feature point information will need to be reused several times (multirow stitching) > Emaad, I'm glad to know I'm not alone here!

And believe me, it's often easier to first make partial panos and combine them laster than trying to force it with all the images straight away. And once you're in some local minimum, you may not get out, no matter how hard you try, so starting with the positions reset can often help. And do try to use --fullscale or such for images that you find hard to match, it makes a big difference. > I'm going to get myself a robotic pano head, probably a Gigapan Pro > and that will make stitching these things easier.

What do you do - lanscapes, architectural? Some imagery is near- impossible to find control points in (sky, repetitive textures...) - no matter what hardware you use! You might want to consider using 'overview' images shot with a fisheye. These can be very helpful to have a sort of backdrop to 'nail' the other images to. Takes some fiddling and a well-calibrated lens, but it's well worth a try. > Is there a page somewhere that tells where to get all the optional > bits for Hugin and how to configure them? I admit it's a bit of an uphill struggle. I found the best information on the sites of the CPGs, so if you have a look at http://user.cs.tu-berlin.de/~nowozin/autopano-sift/ http://autopano.kolor.com/ this might give you a good starting point.
