Yes, hopefully the PTO file has the optimisation parameters correctly set up 
for a mosaic project rather than a traditional panorama - there is a tutorial 
on the Hugin website that explains how aligning scanned images works.

Each control point in the PTO file is a line that starts with 'c', you can 
delete them without corrupting the file. The file format is documented here: 
http://hugin.sourceforge.net/docs/nona/nona.txt

[hugin-ptx] Re: Could not decode image error in 2019.0 beta 1

2019-02-15 Thread Abrimaal
*In beta2 Pre-Release 2019.0.0.75168618c648 the problem has grown.*

There is no "All Files" filter in "Add Images". It means that it became 
impossible to right click a .pto file and open it in another instance of 
Hugin.
"Add Images" window is the fastest method for quick preview of a finished 
panorama, because it opens the folder, where the panoramas and .pto files 
are saved.
If the panorama did not look perfectly, it was very simple to send the .pto 
file to another Hugin instance and work on it without running around drives 
and folders.

Re: [hugin-ptx] Automatic stitch scans of engineering drawings hopeless?

Hello
Thanks for your suggestion.  After slightly modifying the sticth-scan... Python 
script I have an output.pto I can open in hugin and add control points.  I 
assume need remove points on repeated features as well, optimize and stich.

Is that basically correct,
and can I delete control points en masse from .pto with vim
and where might I look for basic info such as this preferably in scan/mosaic 
(only a guess that) context?

I realize this is my problem not yours - thanks again.

Regards
Jc

Re: [hugin-ptx] Automatic stitch scans of engineering drawings hopeless?

2019-02-15 Thread Bruno Postle
Any automated tool like this is going to fail some of the time, especially if 
your images have repetitive features.

I'm not familiar with stitch-scanned-images, but I would expect that in 
addition to producing a stitched image, it would also provide a PTO project 
that you can open in Hugin to fix any errors.

[hugin-ptx] Automatic stitch scans of engineering drawings hopeless?

2019-02-15 Thread jim cullen
Hello
I'm trying to stitch 24 scans into a 2x3 foot drawing using 
stitch-scanned-images which is a python script on sf gethub.(Running hugin 
2018.0.0 macosx)

First row alone works well.

First 2 of second row fine.

Third scan row 2 has a couple of features with very much in common with second 
scan row 2 and it gets rejected from stitching.

Is it even possible to automate the stitching of scans in this case?  There are 
good reasons the drawings seem so repetitive.

Any direction in this most appreciated.

Jc
