nona, verdandi and --wrap parameter

[stephan...@wanadoo.fr]

Hello !

I'm trying to use Hugin to batch stitch many partial equirectangular panorama made with my custom rig (Xiaomi Yi 2k x4)

With my images, Verdandi seems to do a better job than enblend.

But when I use theses option in my base.pto :

#hugin_blender internal
#hugin_remapper nona
#hugin_verdandiOptions --wrap --seam=blend

The script stopped with this error :

/usr/bin/nona: invalid option -- 'w'

Is that a bug ?

But I can set the --wrap parameter when I use Verdandi separately on the command line.

For partial equirectangular panos the wrap switch is not needed.

#hugin_verdandiOptions --wrap --seam=blend

The script stopped with this error :

/usr/bin/nona: invalid option -- 'w'

Is that a bug ?

The wrap parameter is automatically handled by nona/hugin_stitch_project/PTBatcherGUI depending on the output settings in the pto file. There is no need to fiddle with that parameter by hand.

Do I understand this exchange correctly? I had thought that it
implied that the --wrap option in hugin_verdantiOptions was causing
the invalid flag -w to be passed to nona. If that's the case, I would
have thought that this is a bug.

Thank you for these answers.

So, I think my problem is something different, but I don't understand:

Sometimes I have a bad blend, but not on a seam. Look at this straight vertical line:

And sometime I don't have it. I tried many parameters, methods, hugin release, operating system, and I don't see what makes the difference.

But I never have this problem with enblend.

Hi Stephane, I've never used Hugin, but those of us who are panographers use Ptgui or Autopano Giga, 

which go better!  Maybe you can try a free evaluation version, and if the problem continues, 

you will have to see if the capture is correct or not, maybe you shot with automatic white balance ... can be one of the causes!

Javi.

Okay, there is also a offset at the 360 deg border.

With these files I could reproduce the issue. This is a bug in verdandi/internal blender.

I've fixed the bug in the repository. Now the vertical line is gone and also the problematic file looks fine.

Thank you Thomas !

I'll test a release with the fix as soon as possible.
