Fake bracketed

[Jerome Boccon-Gibod]

Hi, I would like to align as precise as possible 5 drone panoramas taken (almost) at the same position at different times.
I was thinking of "faking" bracketed images to be able to align them but not link them, and then to export the different "fake expositions".
Doesn't looks it possible, or I haven't found how.
Or maybe someone has another clever solution ?
Many thanks

Jerome, In principle, you can align the set of images just like any other images.  Load them in, create control points, run the Optimizer and generate individual output layers as jpeg or tiff files (or whatever you need).  This is a simple operation if you are working with full 360x180 images, but complications may arise if your input images have been cropped assymetrically- e.g. to remove black space.  Probably use individual lens parameters.  If you roughly align the images manually by dragging/rotating in the Panorama Editor window, you can use the Generate control points here function to help things along.

You could do it in two ways. One is to first stitch each panorama, and
then load all panorama in a new project (as source images) and align the
panoramas.

Or you can just load the source images for all panoramas in a single
project (fake bracketing is not necessary). Hit Align Images. Then in
the Create Panorama tab use the 'include images' list to output a
panorama for only one set of images.

Both have their trade offs. If the images were taken from exactly the
same viewpoint, without parallax, the second method would work best.

If the drone was moved a bit between panoramas, the second method will
cause stitching errors within the panoramas. The first method would give
good panoramas, just the alignment between them might be off.

Kind regards,

Thanks for your replies !
I finally dropped all the images in Ptgui and the result even if not perfect is quite good : https://www.360images.fr/visites-virtuelles/insolite/time-pano-panorama-360-temporel.html
