We used photogrammetry on a very large outdoor compact range reflector to align the individual panels to ensure they fit the parabolic section curve needed.
Interesting tech. We had to print YUGE sheets to place on the structure with various sized dots so that the image could map the structural excursions. We checked to see if the dots should all be the same size and were told they would produce better results if they were varied. Fun stuff. Long ago and far far away.
