Should this have worked better?
This workaround shouldn't be necessary if you have autopano-sift-C
2.5.1, you can use these parameters in the Preferences (the list of
input photos is supplied within a temporary file):
Program: autopano-sift-c
Parameters: --maxmatches %p %o %s
Also completed a trial using imagemagic to mask the coloudy bits
and the lower foreground (i.e letterbox 8) did control point
detection etc. on three images at a time, and combining them as
you suggested with pto_merge. The output from this was worse
unfortunatley. 57 disconnected regions vs 35 from hugin.
It is difficult to say without seeing the project. Can you open any
of these three-photos project files in Hugin and see anything wrong?

That is the question tho. what parameters should I optimize? I
have a linear panorama, all points should be good, and no matter
what optimization I do I get nothing like what I would expect. all
images are lumped together. Henc I revert to asking the gurus
8).... what is *supposed* to work for linear panorama? (bearing in
mind it was a 10-22mm Canon efx (1.6x) lense at 11mm so lots of
distortion).
For a linear panorama where the camera changes positions, the
subject is a flat surface (like a mural), and the initial estimate
of field of view is approximately right. With the current Hugin
trunk, you only need to optimise 'Positions and translation'. After
that you can try optimising 'barrel and view' too and see if this
improves things.
