Hi Pierangelo, Thanks for this advice, i’ve downloaded the Pix4dreact trial and it processed this well. It’s got some small gaps but great coverage for the full extent of the seagrass beds. So it’d be good to know how best to proceed with the fix- Would this involve the purchase of Pix4dreact?
Additionally to this problem is another large piece of our photogrammetry work we have has been trying to create photogrammetry mosaics from underwater video (similar to this conversation - Importing Photos Extracted From Video). Again I hadn’t really understood the differentiation of the different Pix4d packages and thought Pix4dMatic would cover these needs. I have been attempting to create the correct Metadata using EXIF tool and ffmpeg for extracted frames but not got there yet. It may be worth having a quick call at this point if that’s possible?
