I have a camera mounted on a rail, so that I can digitize large pieces
of flat artwork. The rail allows me to shoot a series of pictures
parallel to the surface of the canvas, basically acting like a very
large format scanner.
To stitch them together the pictures into a huge file I use Hugin.
As an example I have is 5 columns (say 1 to 5) and 6 rows of images (say
A to F).
If I do the automatic control point finding there are endless errors, as
I end with false control points on images that have no overlap.
I've tried cp_find --multirow, but even then the program tries to match
each image with many others, not only slowing the process but creating
many points that have to be cleaned up manually.
What I would love is to create control points only for the images that
are next to each other and no others, so that each image will only be
connected with control points to max of 4 of the adjacent pictures.
something like: A1-A2-B1, then A2-A3-B2, then A3-A4-B3 and so on...
I've been creating the control points manually, selecting pairs of
images on the same row, clicking on the "create control points" button,
and then going over the same process for the columns. The results quite
accurate with this workflow.
I would love to create a script that automates all this, as it is
tiresome to process 30 images per project (and I have several paintings
to digitize)
I can't find information on how to create such a template. Any ideas
are welcome.
I don't know anything about scripting this, but does the --linearmatch
option handle matching images better? That matches image 1-2, 2-3, 3-4,
4-5, etc.
I don't know what it would do when it hit the end of each row. I suppose
it might try to match images 5 and 6 (end of one row, start of next).
Not what you want.
Perhaps you could precede these steps by using pto_gen to generate a
separate PTO file for each row of images, run cpfind's --linearmatch on
each separate PTO file, then use pto_merge to merge the resulting PTO
files all into a single project file.
Ideas?
