I have been using ODM for several months and it works on most of my images.
I used to take photos at an altitude between 50 to 200 meters (using a programmed DJI mavic 2, overlapping rate at about 70%), and ODM always produces acceptable result.
Recently I am trying to stitch photos taken at 30 meters high. This time, however, ODM produces scrappy results (like the image below).
I have tired multiple times, and it seems that this only happens when the height is below 50 meters.
Why would this happen? And how can I fix this?
