Thanks for the comments, much appreciated.
I will see if I can generate some non-sensitive, photogrammetry suited sample data. In the meantime, You can find some DNG's here: https://drive.google.com/drive/folders/1TACxCBcZrJ2P-qQNLdbzphU_5G0CVjcB
I managed to make ChatGPT 4 make me a python script, that would split the images into seperate folders, so Metashape would easily import these as a multi camera project. After trying to figure out pixelpitch and focal length (this was a pain, with little to no hard spec on the sensor), I managed to get a very decent result, where some manual markers had 0.3 px precision as compared to the 3 px precision when I was using the equirectangular images made with Insta360 Studio.
So far, so good!
