Re: [hugin-ptx] Help aligning multiple panoramas

[Carlos Eduardo G. Carvalho (Cartola)]

Have you tried to align them after they are finished? Don't know if this is the best option, but I did it in this case here:

The second picture was taken more than one year after the other and I aligned the two equirectangular at the end. I did it manually into hugin, but it is probably an easy task to automate.

Hi,

I just started using hugin recently, and while I've been reading a lot, I could use some help/guidance from the experts here.

Case at hand:
I have multiple 360 panoramas, taken from the same position, at different times of day, using a motorized head.
However, there are slight rotation differences between each set of pictures (and probably the whole rig moved a little bit).

I have a papywizard template that I've used to set up a generic .pto to read in Hugin. Now, I can go in and add CPs, optimize, etc, and get a good panorama for each one of the sets, but if I do each one separately, they are all slightly different (in rotation, but also different areas get warped differently).
Ultimately, I'd need all panoramas to line up perfectly with each other.

Ant tips for the best way to go about that? I've tried extracting rotation differences for each set, and then using that to modify the master .pto file to create a "rotated" one for each set. But by the time I add CPs and optimize, I still get panoramas that don't line up with each other.

Help! and Thanks!

Just put all your photos for all panoramas in one project and align
them together. Then stitch it several times, enabling one set of
photos at a time.

Though the loss of data from remapping a second time is negligible, so
I wouldn't worry about this very much.

I share this opinion.

Another option (besides stitch all toguether as Bruno said) is to use the equirectangular just to align the next set of images, keeping it as anchor and don't stitch it again.
