PTgui + distortion
Posted: 1 Jun 2008 at 16:22 GMT

Hello everybody.
Up untill recently I have always stitched with PAnoweaver 5.0. But I haven't been quite satisfied with the result, so after several reccomendations I have bought PTGui.
It is awsome at stitching, but now I've got an other problem: Distortion!
Especially the vertical lines are way off resulting in a strange looking panorama.
Please see an example here:
It should be obvious to see my problem.
See the same panorama stitched with Panoweaver here
What exactly am I doing wrong, and what can I do to correct this problem??
I know there is a Panorama Editor in PTGUI pro to honestly that is very difficult and confusing to use!
Also often the panoramas in PTgui stitch so it is upside down meaning that I have to rotate the image 180 degree in PS. And that is even if I rotate the images under the "crop" tab.
Can anybody give me a suggestion as to what I might be doing wrong????
Best regards
Morten

Hi, Morten!
Welcome to PtGui. I think what you mean distortion is actually levelling the verticals. John wrote an tutorial about it.

Good luck, Martin

Hi Martin
Thank you so much for the link. I will go through the tutorial tomorrow and see if I can improve my panorama.

Hi Morten,
I was having the same problems and then took John's advice. I've stitch every pano with t1 control points from then on. It's incredible how accurate your verticals become ... without a lot of fiddling. John told me it would add another 40 seconds to my stitching time - those are the best 40 seconds of the entire process in my opinion.
Looking forward to hearing how you do after reading John's tutorial.
Regards,
Tom

Hello guys.
So i tried following the tutorial (I didn't have time untill now) at a different pano, and it worked great. I just assigned 2 vertical lines to all 4 shots (4 round @ 90degree) and the 8 new control points fixed the problems 
This will most likely be part of my standard workflow from now on as most of my stitching in PTGui seems to suffer for the lack of vertical control points.
Now I just need to get the Enfuse function to work properly so I can speed up the workflow when I need to do multiple panoramas.
Best regards
MOrten

Morten, enfuse is really simple to use. After installing, you will find 3 enfuse shortcuts on your desktop. Just select all the exposures of the same image that you want to blend, and drag them on top of the Enfuse shortcut. A DOS popup will show, and the blended file will be created in the same folder as the originals.
Or you can stitch all the different exposures using the same pts file, and drag those on top of the Enfuse360 icon. This will also take care of the '360 seam'.
Regards,
Ronald

Hi! Sorry Morten for using your thread for this.
Vilmer can you post the link where I can download enfuse?
I already downloaded one but I do not know if it is the same, so I can check it out.
Thanks, regards, Martin

Good, though 8 points was overkill. 3 should be adequate.

Hello Ronald.
I am the owner of photopla.net and publish a Windows package of enfuse.
May I ask you *not* to post deep links? the version you link to is old, and there is a lot of manual work involved in setting it up.
The latest version can be always found on the download page, and this is where I kindly as you to direct people in the future:
<panospace.wordpress.com/downloads/#devel/>
If you download enblend/enfuse from there, there is no need to unpack, fiddle, or do whatever else. Just a standard Windows installer that does it all for you.
Also, if you are already on that site, please consider Hugin. We are close to having a release, and we have a group of very motivated students adding new features, sponsored by Google and by Nodal Ninja.
For details, keep checking out that blog.
Happy stitching
Yuv
