Hello Everyone,
I don't know if this is a stupid idea, but it seems possible in principle.
I want to stitch a very long pano that causes all versions of APP that I have (Win APP 1.4.0, Win/Linux 1.4.2, APGiga 1.9.0) to crash. Is there any way that I can use APP to stitch the two halves of the pano separately in such a way that I can put the two halves together seemlessly?
My guess is that if I do this naively then the projections will not match up.
Aeris.

Hi Aeris!
Would be interesting to know how big it has to be in the end . . 
resp. how big you tried to do.
Do you mean "two halves" to combine horizontal or vertical?
I sometimes merged panoramas - if you merge them in the editor and render them afterwards the projection should be ok.
I guess at least the APG version should work - doesn´t it? The only problem could be RAM and disk-space - maybe you should try it on a 64bit system with at least 16, better 32GB RAM and some terabyte free diskspace for APP.
How would you combine them otherwise . . 
- maybe in Photoshop after rendering the partitial panos.
best, Klaus
(tell us how you proceed!)

I don't know if this would be a solution, but it would be something I would try in a case like this.
Do everything to merge the photo set up to the point of rendering ... if you were able to get that far before. Then use the crop tool to crop the big pano down to a smaller part, half, or third or quarter, or whatever. Then render that. Then go back and change the crop to the other part(s), and render those. Batch all the renders and let them work.
I'd think that would have the best chance of lining up in the end. The worst case I can imagine is one would be half a pixel off from the other (don't know if that would matter for your situation).

Yes, that will work in theory. I've never tried it in APP. That's how I used to do gigapixel images in stitcher 4+ years ago, before any stitcher had .psb output.
Using APG, I have already optimized an image past 300k in the horizontal direction. So I would try APG. Klausesser wasn't joking either.

Thanks for all your comments and ideas. Phil's idea is an obvious one that had not occurred to me - thanks, although it does assume I can get past the stitching phase so that I have something to crop, and it is the stitching that is the problem.
With regard to Klaus's remarks, actually, there isn't a specific image that I am having trouble with. I simply had the idea of doing big stitches in two (horizontal) halves and started thinking about why it wouldn't work. Projection came to mind and also colour control. I guess I need to experiment.
Gerard, what are the specs of your system and can I have it please? :-)
My system is a quad-core Linux 64-/WIn XP 32-bit box with 4Gb ram and I don't have the money to upgrade. In fact my current system *is* an upgrade :-)
I have more examples of panoramas that don't stitch - presumably because they are too large for my system - than I care to mention. "Too large" is not well-defined but anything over 600 images is unlikely to work. My largest image group is 1500 images (3*500 bracketed).
I have APG for windows and it is very impressive in the speed that it works, but it crashes 95% of the time so I don't bother using it now. I did notice the other day that there is a version of APG for Linux but I don't know how to install linux software. It might be worth trying if someone can tell me how to install it. I am using Ubuntu 8.

Installing Autopano Pro on the Ubuntu 8.04 distribution of GNU/Linux is quite simple.
1. From your browser, click on the link for the appropriate .tar.gz file. For you this would be http://ftp.autopano.net/releases/Autopa … -10.tar.gz.
2. Save the file in a folder named AutopanoPro in your home directory: choose save file and OK, then from the file selector navigate to your home directory and select create folder. Type AutopanoPro for the name of the new folder and choose Save.
3. From the desktop, select Applications -> Accessories -> Terminal to get a shell prompt.
4. Set the current directory to the location where you downloaded the .tar.gz file: cd AutopanoPro
5. Uncompress the file: gunzip AutopanoGiga_Linux64_190A1_2008_09_10.tar.gz. Note that you can use the tab key after gunzip Auto to have the shell type the rest of the name for you.
6. Expand the .tar file: tar -xvf AutopanoGiga_Linux64_190A1_2008_09_10.tar. Again, the tab key will save you some typing.
7. Descend into the folder created by the tar command: cd APP
8. Run the program: bash AutopanoGiga.sh.
To run the program at a later time:
1. Select Applications -> Accessories -> Terminal to get a shell prompt.
2. Descend into the program's folder: cd AutopanoPro/APP
3. Run the program: bash AutopanoGiga.sh.
Please let me know if you have any difficulty with the above, or if it contains any typos. I will be happy to improve it.

When it only remains to render the pano (good RMS, etc, etc) but it's "too large for the computer" the Layer Editor is the tool to use!

John, Georges,
Thanks you both for your posts - the prospect of going even bigger than before is very exciting. And as the regular readers of this forum know, size is the only thing that matters!
Georges,
I don't quite understand. How do you create the left- and right-layers? Create new layers and simply drag the images you want onto it?
Frantically busy here with no time to experiment - I am looking at my first ever sale! This pano is proving to be very popular despite the many things that are wrong with it.

1) Create a single new layer. Names don't matter. They were (easily) changed for clarity of illustration but automatic names are OK.
2) Select then drag images from one layer to the other one. It's that easy!
...Easy but, if one have several hundred of images this could be quite tedious. Multi-selection is possible and should help. If you have several thousand of images, just ask Alexandre to add a new button to create layers using yaw values as a criterion... If he is too busy, somebody could make a script to do that from the .pano file. 
Note that this feature or script could be worth a lot of gigahertz or at least some Raid 0 disk!

Cheers Georges. Will investigate when I get back from my latest excursion. Have sweet-talked my way in to Fort Purbrook. It's interesting how many doors you can open by saying "I am ... Global Connection Project ... National Geographic Magazine ... NASA ... Google .. free advertising?" :-) (Fill in the blanks depending on your particular interest with the gigapan project.)

You are in a different place! Round there, words like global, connexion and even projet are to be handled with some cares...

None at all. I thought you might like to know that. Thanks. Maybe this could be added to the Wiki?

Thanks for testing the procedure. I have added it to the wiki here: <http://www.autopano.net/wiki/action/vie … ar.gz_file>. In moving it I tried to make it more general, so it handles both the current production version and the latest Beta. I would appreciate any feedback.
