Panorama of Long Wall - Problem Stitching

HI there!

I have problems stitching a panorama of a long wall. As you can see in the first picture below the beginning and the end are stitched together - although they don't have anything to do with each other (2. picture).

I also posted the prefs below.

Here is the link to the picture set: http://uploaded.to/?id=2mb2xz

Did it with a Canon Eos 350d and the standard lens.

Distance about 3-4 meters (9-12 foot)

Hope someone can help me wink

Re: Panorama of Long Wall - Problem Stitching

???? a bit more of information would possibly be helpful . . . . cool

Which lens, camera, setup, shooting, distance - which focal-length in the lens-prefs. Why using "adjust lens distortion"?
Does your lens produce any?

best, Klaus

Re: Panorama of Long Wall - Problem Stitching

Use the Control Points editor and remove the link between the first and last image. Then Optimize and after that - use the Center Point tool to set a center point for the pano.

Re: Panorama of Long Wall - Problem Stitching

I solved it partly:

nothing was wrong with my config. Reducing the image-count did it.

There seems to be a limitation in the Aspect-Ratio of the panoramas - so you can't make VERY wide panoramas - at a specific width the panorama overlaps (as seen in my picture above).

Is this a bug or is there a setting somewhere to fix this problem? Hane not found anything

Maybe you are right. I never try APP doing a larger panorama than 360x180° lol Probably some trick can do it.

Re: Panorama of Long Wall - Problem Stitching

Dear Karlo, you are a new member, may be new to panorama first.
When you like to post pictures, we genererally prefer that members use the upload integrated in this forum than sending us to outside servers that always add some stupid "Ads"or "PopUp". Thank you.

You said having taken a "panorama" which is basically taking pictures around a center point, and user spend money for a good tripod and pano head to make sure the pictures are taken around the NPP (Non Parallax Point) of the lens.

Seeing your pictures, I guess that you just walk along a wall, taking handheld pictures, not always at same distance from the wall, not always perfectly perpendicular to the wall. This is not panorama but "orthophoto" or "like scanning".

To do this, you should stay always at same distance from the wall and take pictures perpendicular to it (just think that you are a scanner lol ).

After loading your set of pictures in the detection group, click on "images properties" button. In the "Settings" window, write 1000 in the control under "Focal (35mm eq.)

Click on the "Open settings" button, make sure "Adjust lens distortion" and "Advanced distortion"checkbox are unchecked.

Then you can launch the detection. You should have better result.

Before thinking that a software may have bugs, please, please, make sure you use it in the rigth way.

Re: Panorama of Long Wall - Problem Stitching

I haven't attempted stitching the wall yet, but may I suggest to you to shoot from left to right in future, as it makes sequencing images a a whole lot easier. Less stress on the brain! lol

Okay, I made one attempt, and I got what has become known as an Alexandroid big_smile

Re: Panorama of Long Wall - Problem Stitching

Hi DamoRed, your pano is much more beautiful than my stitching lol nice Alexandroid !
Could you check that you don't have too many links between "far" neighbourghs, I mean pict#1 -> pict#2, pict#2 -> pict#3, but also pict #1 -> pict #3. This one may be of weak quality and lead to heavy contrains in the panorama, just try to delete too far links.
Of course, don't delete this *.pano file, somebody may be interested smile

Re: Panorama of Long Wall - Problem Stitching

With apologies to Pink Floyd...    and Karlo! tongue


Karlo needs some education,
Panos need some point control,
The forum here will be your classroom
you cannot work handheld alone.

Use... tripod, leave handheld alone!
Now you go and get... another pic of the wall
Bring a tripod and get another pic of the wall





Okay, okay, I know that working handheld is possible, I've done it myself. But the conditions must be right, it doesn't work all the time. Just consider it artistic licence for now! cool

Damo

This concerns 'stress on the brain' One reason for that stress is the order in which images are displayed in the Control Point Editor  At http://www.autopano.net/wiki/action/vie … nts_Editor and 'Add Control Points' the documentation makes the point that you can display images in the reverse order by re-sorting on the image number [#] column

marco-pano is quite right. I got an excellent stitch of your image set following his advice. View it as a Flash pano:
http://www.three60views.org.uk/graffiti … ti_02.html

You might also find it interesting to try Photosynth with this sort of image set?:
http://livelabs.com/photosynth/

It's Windows only at the moment but wider platform support promised.

This is the sort of result you get:
http://photosynth.net/view.aspx?cid=57C … 7D47A34D60

There's not sufficient overlap between images - Photosynth 'likes' about 50% - to link all the images together but it has linked several subsets and left some orphans. Photosynth does quite well with these orthographic images sets.

It is a far from conventional 'stitcher' but has many interesting features and characteristics.

This is what they wrote before their website crashed my browser:
"Unfortunately, we're not cool enough to run on your OS yet. We really wish we had a version of Photosynth that worked cross platform, but for now it only runs on Windows. Trust us, as soon as we have a Mac version ready, it will be up and available on our site."

So I appear to be running Macintux! big_smile

Re: Panorama of Long Wall - Problem Stitching

Yes, a great work but unfortunately I don't have the author name. This is a 3x360° : look the picture you can see 3 times the same trees but different people in front cool

Re: Panorama of Long Wall - Problem Stitching

Marco, I love that idea. I'm thinking about trying it for a friend's wedding in a couple of weeks. First condition, if the weather is fine and suitable.. and if I can get everyone away from the bar long enough!

Just thinking about the headache it will be to organise it... 'ok, you're done, scoot...now, Sir & Madam, can you please take that spot and don't move until I come around again'.


1080º later.. "I'm dizzy, somebody get me a drink" tongue


I'm not the main photographer, (And they're not getting a wedding album anyway) so I can spend a little time on it without worrying about the 'money shots'. It may be a case where I can only get the Bridal Party and a few family and do one rotation. If so, then that's okay too, I can then close it at that and they've got a rather different image and a movie for their website.

I've photographed weddings on my own a number of times and I know how time can disappear so easily. Doing something different like this would definitely not have been possible, even if I'd known about panoramics then.
