Panorama superposition: different stiching size

by tranceorbitale » Mon Jan 25, 2016 6:45 pm

Hello,
I want to make 3 panos 360° that can be perfectly layered. I made them by shooting at 0/90/180/270 with a fisheye. The support didn't move b

0/90/180/270 - original
0/90/180/270 - 1 thing changed at 90°
0/90/180/270 - 1 thing changed at 180°

However, when I stitch them in Autopano Giga 2.5, I get 3 panoramas with different size:
-9800x4488
-9848x4500
-9824x4512

Do you have an idea on how I could make them layered perfectly ? With exact same size ?

hi,
maybe one way to try to do that : put your first images in PTP, render, control points, line,etc ... save the project with the option extended ( include the files ), render the first equirectangular. Quit APG.
in the folder associate to the project, change the first files by the second one, after giving the second one the same same name than the first one, open the project, render without modifying anything else ... an other way if you are fluent with xml is to use the import, papywizard and xml file, but you have to write a xml setup of importation before

Good idea but it doesn't seems to work for a perfect layering.

When I open the saved project with modified images, APG restart automatically projection. And as images have little difference, it changes the stich a little so when I get my final render, there is not a perfect superposition for the view I replaced.

Is it in the same scene but with slight differences? If they are similar enough, why not try bracketing them?
That way each layer will be a separate panorama, aligned and all the same dimensions, which you can then render separately.

It's a bracket pano of 12 images (4x3).

I made twice one angle with little difference (something moved), and I'd like the 2 bracket panos to be layered perfectly

Could you show your images? It would be easier to try and find a solution.

photos unstiched to download: download


For first stitch you have to use 12 pictures without "c", for second stitch you have to replace 3 by the "c" ones.

hum, I just saw that my unstitched pictures are not perfectly layered, so a big part of the problem comes from here...
I'll take new photos

So you want three panoramas out of those images? or two (one with the c images, one without)?

Or six? (each bracket layer times two for the c photo variants?)

I use autopano 2.5

I want 2 panos, one with "c" photos, the other without "c", with a mixed exposition.

Quick test:
15 107_0000.jpg
15 107_0001.jpg


It isn't perfect because the brackets weren't correctly aligned, so there is some ghosting, like in the ladder. And I didn't bother with the fusion.

My workflow, using Autopano Giga 4.2.3:
1) Input all the images into a detection group (c photos and non c version)
2) Manually stacked them by groups of three, so i have a stack of my c photos
3) Detect
4) Open the panorama editor
5) In the layers editor, uncheck all the c photos
6) Do all your colorimetry and fusion edits, and render
7) Uncheck all the non c versions, and check the c photos
8) Repeat step 6.

My layers look like this:

I don't know if it is possible in APG 2.5, Autopano's detection capacities have improved quite a bit since that version.

The method is perfect but I have a strange result.

After unchecking one or the other, preview get actualised. So for each pano I make rendering.
However, the result gives 2 same panos with mixed images "c" and "not c"

I managed to do something in a second test, I had first pano not mixed contrary to previous time, and I had the second one good but only after deleting photos from groups.
If I just uncheck, it is the same pano that is rendered.

I do not undertsand how it worked this time so I am not sure to reproduce it successfully
