Hello,
I'm just getting started with panoramic photography.
I noticed that each time I process a batch of pictures to detect the panorama, the image size changes.
E.g.
Batch 1 has 9 pictures all taken at 40º intervals ---> stitched image size is 20143x3051
Batch 2 has 9 pictures all taken at 40º intervals, same camera / tripod / lens etc. ------> stitched image size is 20630x2987
So my question is, how can I make sure that all panoramas produce images of the same size in the end?
I'm asking because I want to make a virtual tour, and having images of the same size is a must.
Thanks!

1 way and 1 opinion which may not be satisfying for you...
1. crop the panos in autopano using the cropping tool
2. if you create a tour no one of your users will see that pano1 is 150 pixel smaller in x or y than pano2, because the distance from camera to object on each pano is different, different focals may be used, different light conditions and many other factors will give the viewer the feeling to always look at different sized panos, even if they are exactly same sized...
Liebe Gruesse,
Georg
PS: if you have on nadir or zenith a white wall or wooden floor... than you could enlage the too small panos and using retouche to add "the missing pixels..."
in fact, even if you take the same 50 images of your pano and you create 10 different project with the same images you will see that the pixel dimensions will differ..

While I agree with you, for my project I need panos to be very consistent and predictable.
I have a plugin that visualizes a series of panos in sequence (like a tour, or like street view if you want). Now, these panos have hotspots at specific locations on the image (eg. a blue window in Pano1 located at 500x800 pixels). When I move to Pano2 (the next "step") the plugin recalculates the position of the hotspot to place it again over that blue window.
That's why I need the pano's to be the same size and aspect, and most of all they need to be consistent with each other. I understand I could crop, but that might mean that in Pano1 the horizon line is at a different height than in Pano2, in turn that would screw up the hotspot location.
P.S. I know there are flash plugins and software to easily make virtual tours, but I must absolutely use the plugin I described above.

I would not rely on the content to give you absolute exact number ( focal, could have changed a little because of focus point not at the same location ).
So in your case, instead of rendering at 100%, just enter the same number as width and it will work ( 20000 for example ).
