Great video. It's refreshing to watch unscripted behind the scene discussion of photogrammetry applied to the extremely difficult process of bridge inspection. You described video acquisition separate from photography for photogrammetry. Have you ever tried photogrammetry from extracted video frames? Seems like it could be useful at a minimum for referencing video time codes to 3d position on the bridges. Obviously a 3d scan result would be much more accurate and high quality. I've done photogrammetry from Skydio drone video frames many times with good results. You just need to use photogrammetry software that doesn't require GPS as most video doesn't contain that data throughout the flight. I'm hopeful once remote ID is implemented GPS will be recorded every second or with every frame. Looking forward to more informative content on your channel.
I'm discovering that winds/wind gusts well within the limits of my Skydio drone wreak havoc with my 3D building scans. Some parts of resulting 3D models look really nice, and others look terrible. I'm pretty sure the terrible parts correspond to periods when the wind kicks up. It would be interesting to hear your experience and wisdom in dealing with winds when doing 3D scans.
