stitch portraits together not landscape

[Michael Havens]

I've been trying to do indoor panorama with no success. Until I turned the camera on it's side and took a series of 5 portrait oriented photographs. The resulting panorama was on it's side but other than that it was perfect.   

 The attached file is the final image after it has been rotated

[Michael Havens]

I struggled with sharing that because I am afraid that now that I shared this it is going to be 'fixed' but the fix will make it worse.

Hard to see how a fix will make it worse.

It would be helpful to at least provide your .pto file for your original
project (the one which was unsuccessful).
If you were able to also provide your original 5 images (via Dropbox or
similar service) we might be able to get a clear idea of what is going on,
so we can either point out what you can do to overcome the issue, or to
decide if hugin has a bug.

Cheers,

Also what version of Hugin? I had a version or two ago that would not
properly align a vertical pano made from portrait shots, but would
happily produce the same pano (rotated horizontally) if I rotated each
image outside of Hugin before trying.

Haven't had that problem for a while though. One of the updates seems to
have fixed it.

I also included the first portrait pano I did. It was less successful than this one butbetter than any other I had done before.

I loaded your images into hugin-2016.2.00-RC1, and didn't have any
problems at all, see the screenshot attached. I have also included my .pto
file.
You provided the portrait images...I thought your initial problem was that
hugin couldn't handle your images shot in landscape, so why provide the
portrait images?

What OS and version of hugin are using

loaded the images into the latest hugin, generated control points and
vertical lines for all the images and then went through the optimization
steps up to everything without translation. autocropped the file and
saved it. loaded into gimp to auto correct the white balance. this was
done on linux.

I thought that it may have been that I didn't optimize but that turned out not to be the problem. When I run align it automatically finds vertical lines so it doesn't ask me to do it. Well, after fiddling with it a bit I find that if I click 'straighten' in the align/move tab it gives me what I want but when I click the 'create panorama' button only a small part of of the desired image is stitched together (images two and three). Any Ideas as to what is wrong?

OK, thanks for that.

So, is there still a problem with landscape images that we need to sort
out?

[Michael Havens]

well, I figured out that I got lucky with this panorama. most of my indoor panoramas don't turn out. I am told this is due to paralax.

OK, that is a common problem shooting handheld and particularly indoors
where you often have items close to the camera.
You can reduce parallax by being careful with the way you rotate the
camera, to ensure you do it about the nodal point, and by using masking to
selectively avoid the parallax errors in the stitch.
If you haven't already done so, do a bit of reading on how to find your
nodal point, and search for methods of shooting handheld panos. The string
and drop-weight trick is a good one to help you get a good idea of how to
do it.
Let's know if you still have any other problems with hugin.

[Michael Havens]

okay, but what about this image were it mostly works? How do I get that light rectange (which is what is showing up in the panorama)  to be bigger?

Do you think installing the release candidate will fix this?

[RizThon]

Concerning the "light rectange", is Hugin simply cropping too much for some reasons? That is it's keeping only that small part of the image? Can you check the "Crop" tab?

Did you set those crop boundaries or did it just happen to be like that?
If I understand your problem correctly, just go to the Crop tab and drag
the boundaries to where you want them, or simply select 'autocrop', then
you can manually adjust the boundaries from there.

Not sure, I can't recall any of the recent versions doing that.
If you start the project from scratch (i.e. don't load in an existing
.pto), by loading your images, finding control points and optimising, then
open the Fast Panorama preview window, does it display a cropped image, or
is the crop boundary set to it's maximum i.e at the edges of the FPp
window?

[Abrimaal]

I usually take photos for panoramas in the portrait orientation, because it is simpler to stitch less rows of photos that cover almost the same area.
In this case you should
- when you take photos, rotate the camera around its axes, that the matrix is always in the same place, it will avoid parallax shift.
- adjust the vertical lines, remove the wrong ones and add some manually
- use cylindrical, equirectangular or Mercator projection
- remove some control points placed on the nearest objects

[Michael Havens]

How do you place/remove vertical lines?

Regardless, I started the computer today, opened a .pto and the crop was correct. I'll look at the crop tab next time this happens.

Thanks.

Have a read of tutorials if you haven't already done so, I think much of
this covered but probably using the old interface. If it all still a
mystery please ask again and I'm sure someone will give some detailed help.

[Abrimaal]

Open the Panorama Editor
View the same image in two panels
To remove: click on the point and Delete
To add: click on the picture in panel 1 and panel 2, then Fine-Tune
Next image pair, repeat for all
Align again

[Michael Havens]

thank you for that!
