PTGui "Align" rotating some source images. What to do?

[David Halperin]

I've done several 360 degree panos in PTGui using the same lens
(Tokina 12-24mm at 12mm) without problem. But with one batch of JPEGs
it's different. They load and display normally in the Project
Assistant, but Alignment results in a completely chaotic jumble in the
Editor window. Going back to the Project Assistant I see that PTGui
has spontaneously rotated some of the images 90 degrees (which
explains the chaos). The number of rotated images varies: has been 2,
has been 4 etc.

Why, and what can be done about it?

Thanks for any help you can offer.

[John Houghton]

David, The orientation of the images in the Project Assistant tab
simply reflects their orientation in the Panorama Editor window. The
cause of the jumble is probably misplaced control points. See the FAQ

Thanks, John.

However I suspect the problem may lie elsewhere because I have shot and pano'd this same room before with no stitching problems. It's a residential dining room so there are plenty of reference shapes for the algorithms to work on. I could understand a few control point adjustments perhaps being required, but surely not something as gross as this?

Any other ideas?

Regards

David

In fact I have checked existing control points and added a bunch of
new ones, and the problem remains

Any other ideas?

Hi David,

Sorry for the delay in your posting, it was caught by Google's spam filter.

Please post your images and project file (see 3.17:
http://www.ptgui.com/support.html#3_17), I'd be happy to take a look.

Have you checked that all of the image thumbnails are displayed in the
same orientation on the Source Images tab?

Have you checked for control points between images that are not
immediate neighbours? If any found, delete them.

How bad is the optimization report? One way to discover the errant
image(s) is to do the optimization progressively in stages:

It may help if you reset the y,p,r parameters on the Image Parameters
tab to the nominal values the shots were known to be taken at. This
can be conveniently done by applying an old project file (shot in the
same configuration) as a template via File->Apply template.

Then, on the Optimizer's Advanced tab, check only the main horizontal
row of images in the "Use control points of .." list and optimize that
row alone. (All need to have y,p,r checked except for an anchor
image).

If you fail to get a good optimization, check only the first two
images of the row (in the Use CPs of list) and optimize those two.
Then check the next image and optimize those three. Then check the
next image and optimize four etc. until you get a bad optimization
report. Then check the control points from the last image checked to
other images already checked. Make corrections and re-optimize and
proceed in like manner until all the images are included and a good
optimization is obtained.

If you cannot discover what's wrong, supply the project file and
images as Joost suggests.

This is happening to me too. 

The images are not rotated in Windows preview. 

The project assistant shows image 3, 11, and 12 rotated

The yaw, pitch, and role reads the same as the other images in the bracketed set.

I tried removing the images that had rotated, rotating the rest of the set, then throwing back in those two images. 

The rotated differently when add in again.

I was lucky and my bracketed set had enough overlapping images. 

However, this isn't a good thing. I can send the images that rotate weirdly, where do you want them sent.

Hi Julie,

Please see 3.15:
http://www.ptgui.com/support.html#3_15

If you can't fix the problem please make your project (source images +
project file) available for download. See 3.16:
http://www.ptgui.com/support.html#3_16

I am experiencing the SAME EXACT Issue.  

This has happened many times in the past and most times after an upgrade.  Exiting the program and restarting has solved this in the past but not today. 

I even tried the exact same images stitched yesterday and today they are all being turned sideways and aligning as a garbled mess.  

Please help as I have multiple projects stacking up and am at a standstill until this is resolved.

Radley, You could try stitching the images without using the Align Images function.  See thread at https://groups.google.com/forum/#!topic/ptgui/2EQTF3pav1A .  But if you cannot get anywhere, please make a set of images available for investigation - see the link Joost already mentioned: http://www.ptgui.com/support.html#3_16  .

Hi Radley,

Most likely it's this problem, see 3.1:
http://www.ptgui.com/support.html#3_1

If you're unable to solve the problem please make your source images and
project file available and we'll be happy to take a look, see 3.16:
