I need to process drone collections which have minimum overlap (<<50%). WebODM won’t process them in normal mode, Fast Ortho is very hit/miss. There have been suggestions of using MS image composite editor, but MS has withdrawn it.
Photogrammetry is unimportant in this application. I only want the composite image for situational awareness.
ArcGIS offers a similar capability but at their prices. Maps Made Easy offers a Flat Map. This is what I need, but I’m poor and would appreciate open source.
I’ve successfully stitched quite a few large panoramas together with Hugin, but only with a regular SLR camera, not aerial drone photos. It has generally done a really good job, and I think it should work well with drone photos too.
