Special 'Linear Panorama' - Input wanted

[David Haberthür-3]

Dear all.
I'm returning from a longer hiatus to this list and start with a  
question for a special 'panorama' I've set up at a wedding of a friend.
The idea behind my project is that all the guests are sitting on a  
very long sofa. A friend of mine once setup the same idea with his  
(big) familiy, as seen here: http://arua.ch/pics/40.html
The first quick test of my image-set showed that it should be feasible  
to get the expected result; a lot of wedding-guests on a very long sofa.
I've loaded all the images with ImageJ, and cropped them to a common  
denominator, leading to these images:

http://habi.gna.ch/tmp/gyrenbad/crop_DSC_4443.jpg (yours truly)
http://habi.gna.ch/tmp/gyrenbad/crop_DSC_4444.jpg (my girlfriend)
...
http://habi.gna.ch/tmp/gyrenbad/crop_DSC_4447.jpg

Using the 'mosaic'-function of ImageJ i managed to get a quick-and-
dirty result

http://habi.gna.ch/tmp/gyrenbad/Montage.jpg

Since the thought of blending layers for 69 images by hand in The Gimp  
is not a happy thought and to look for more creative uses for hugin,  
I've thought about adapting the common panorama-workflow a bit.

After setting some points by hand I've edited the .pto-file (http://habi.gna.ch/tmp/gyrenbad/DSC_4443-DSC_4447.pto 
) by hand to iterate the control points joining the sofa in the first  
two images to all the images, or at least to the five images i'm  
testing at the moment.

The result with hugin is quite pleasing already (http://habi.gna.ch/tmp/gyrenbad/DSC_4443-DSC_4447.jpg 
), but two questions remain:
- The mirror [1] does not really work well. I've thought about faking  
a mirror once the panorama is finished.
- I'm thinking that there must be a better idea than "faking" 4*70  
control points in the .pto-file to get a nice panorama out of it.

Does any of the hugin-gurus have an idea on how to improve my workflow  
for this special linear panorama?

Have a nice week.
Habi

[1]: which was hanging skewed, i now know that i should have  
doublechecked with a bubble level :)

Sounds quite logical to me to fake control points the way you do...it's faster than positioning all images next to each other and then creating control points automatically, and you have real control on the output.
As for the mirror, it's anyway probably not 100% symmetrical nor horizontal...to me the best way would indeed to Gimp a fake mirror after the panorama is done. The errors on it are really obvious, but if you modify it and have errors on the wallpaper, it shouldn't be that obvious...

Based on the input images, this is how I would go about it.

1. add all the images to Hugin and *stack* them. output the layers.
2. measure the distance x0, in pixels, of a full "sinus-wave" of the
sofa (from minimum to minimum, from left-of to right-of the guest). If
the stack is right, you only need to measure this on one picture
3. offset each picture by n*x0 where n is the number of the picture
4. edit the mask of each picture
5. feed the so saved pictures to enblend


Think that you are creating a 70 frames movie where you want to
stabilize the sofa in the background so that it does not move.

Once your movie is right, simply putting the frames side by side,
offsetting them by the length of the wave of the sofa will yield the
desired positioning.

yes, fake the mirror, and clone/fake the background pattern too. It will
look better (vignetting and other light issues may introduce variations
to the background).

No faking needed. Under ideal circumstances you might not even need
Hugin (camera plane perfectly parallel to wall and placed; tripod;
neither tripod nor sofa changed position between shoots).

You'll only need to prune bad CPs.

have fun

Since I think the whole piece will maybe be too long to print and hang up in the bride and grooms living-room I was thinking about a little planet. but first I need to stitch all the images...

Thanks for your input, it's appreciated!

Do you mean that I should use Hugin to generate a stacked .tiff-Image  
of all the photos of the guests?

Can this be done with Hugin? I've searched quite a bit, but cannot  
seem to find an option for this....

> 4. edit the mask of each picture
> 5. feed the so saved pictures to enblend
I've thought of something along the lines of http://hugin.sourceforge.net/tutorials/enblend-svg/en.shtml 
  to help with the stray legs and arms...

That's what I've actually done with ImageJ, but I'd prefer the  
correctly blended result using enblend :)
Thanks again and have a nice weekend.

not a single tiff image, but many images. like many frames of a movie.

not that I know. I usually use Photoshop's offset filter.

yes the principle is the same. although you may have to add all the
layers into the blended "panorama" and re-work sharp overlaps (e.g. when
one guest's right leg goes in front (or in the back) of another guest's
left leg.

just leave enough overlap for enblend to work. so when you are doing
n*x0, make sure you crop your pictures x0+2*l wide where l is the number
of pixels you want to give enblend leeway.
