Sub-align photos into project with laser scans 2.2.0
« on: January 17, 2025, 05:24:17 AM »

I’m trying to align additional photos in a project that combines pictures taken on the ground, by drone, and with a terrestrial laser scanner. My method involves adding the new photos into a group, selecting the photos and scans that are already aligned and enabling them to align with the new pictures (for example, those covering the same area with sufficient overlap), while disabling the others (those without overlap). I place markers on the pictures (more than 4) and then run the alignment process.

This procedure worked perfectly in the previous version of Metashape, but now, with version 2.2.0, the result is problematic: the new pictures end up completely upside down, and I can’t figure out why. The coordinate system is correctly set up. It used to work like a charm and was incredibly useful, but now I’m stuck.

What am I missing?
Thanks a lot!

Adding some informations here, because this problem is serious :
configuration of sub alignment
key points are saved
parameters of alignment : Generic preselection, reference preselection, estimated, 50000 key points, 4000 tie points, High accuracy. 4 markers on photos (non aligned and aligned), i disabled photos outside the new pictures zone (952 photos to be aligned)
Windows 10 Professionnel version 22H2
In 2.2.0 complete failure : photos are aligned but located unnacurately
2.0.2 working perfectly
2 files attached illustrating tie point cloud with uncorrect alignment, and one with pictures aligned correctly
