Gigapixel calculation problem

by pranshu14 » Fri Aug 16, 2013 5:36 am

Hello

I have 1456 images of a cityscape and i am creating a gigapixel view.
The issue is the last time I imported the images into autopano giga
it was showing me the final outcome will be 18 gigapixel

but after reimporting those images it is now showing the final size is 12 gigapixel.
Why this change is happening ???

the first import has direct from the camera (jpg) imgs
the second import was imgs with color correction in LR and then imported to the APG
but in both the cases the resolution of the imgs were same.

Then why the final outcome size is changing every time ??

Your pano 18gp shows straight borders, the second does not. Did you do a cropping on the first and not yet on the second?

greetings from germany

What was the shooting pattern.....pattern + overlap + size settings in the render page determins the maximal final outcome. The actual outcome depends on a lot of things. Not all of these are cristaline I'm affraid, since these are programmed using recursive algorithms and these tend to have some life of their own.

Indeed Adrew, that's what I thought as well. Using occams razor it's the only probable explanation.

Yes both were rendered at 100%
shooting pattern was

row wise left to right downward with 25% overlapping.
The image preview is also same in both the cases but not the resolution.

So.. did you shoot this pano with a Gigapan robotic head?

If so, did you use the APG Gigapan Import Wizard?

Hi
Small differences between two separate pano-detections from the same input files are normal.
But this one is a little bit hefty!

Have a look into the layer list at the bottom of the editor and check there the values for the calculated image focal length.
There you will see the difference that happens depending from the EXIF information that were avaible in the input files.
LR can delete some EXIFs that where needed by APG.
Regards
Martin

Show us two screenshots of the first images down in the layer list, so we can see all the values.
