Hi all,
I really stuck with sine-wave horizon on a few panos. Here is a crop:
I drew a cyan line just to show the problem. The "How to straighten a panorama" article on Autopano wiki didn't help. Tried "Automatic horizon", "Central point" and "Vertical lines" - nothing helped with the problem. Tried to add control points to the horizon - the Autopano just doesn't want to add any. The main problem is that horizon on each image was curved by Autopano. Here is the example:
The original image with straight horizon (not leveled by straight) is on left and the Autopano image for stitching in on the right. Gee wiz it was just wide angle shot but not a fish-eye one!!! What happened? Sure if the Autopano curved the horizon on each photo then it's impossible to make it straight on the pano. And it happens on almost all panos when the horizon is visible and the shot is made with wide angle lens.
I tried PTGui - it made straight horizon but it has another problem so I don't want to use it.
Read all Autopano doco, did a search this forum and Internet with no luck. Any ideas how to solve this problem? Appreciate any help.

Hi dewynter
I have run across something similar at times and found the solution was in making sure all the EXIF data was correct.

Hi Tim,
Just double-checked - EXIF seems to be fine. And Autopano recognised the focal length, camera, aperture, shutter speed and correctly re-calculated focal length to 35mm equiv.

Hi dewynter
I should have said, it was that the EXIF said that the lens was fisheye instead of standard, that caused the problem.

Do you have CP at first plan (water?)? Try to remove them, and let only those near the horizon.

Tim, it's recognised as standard lens, not fish-eye.
fma38, thanks! Will try and advise about results.

fma38, you are a genius! That is exactly what I needed!!! Thank you very much!!!!
After that Autopano made almost perfect image that I barely touched in Photoshop (I'm not talking about colour correction).
Ok... here exactly what I did.
1. Created a new project form the scratch.
2. Went through all images and images pairs in Control Point editor and added CPs for horizon. Autopano immediately started complaining about bad RMS.
3. Went through all images and images pairs and deleted all CPs for foreground.
4. Run Optimizer.
5. Deleted some bad links I missed and added a few more CPs for horizon.
6. Run Optimizer again.
7. Straighten horizon and put correct Center point using standard buttons. After that Autopano advised that the global RMS is good.
8. Crop and render.
Now I've got perfect result!
fma38, thanks a lot again!!! You've just saved my life!!! :-)
