Hello everyone!
I use Metashape to create orthophotos from aerial drone missions over forests.
Most of the time, I fly a DJI Mavic 3M at an altitude of 120 metres (the maximum regulatory height in Europe), which produces orthophotos at around 4 cm/px. This resolution is more than sufficient for our forestry needs.
However, I sometimes have problems aligning the photos, especially when flying low (60 m) above a dense canopy. This seems normal as the shots look the same and it is difficult to distinguish one tree from another.
However, last week I experienced alignment issues during a flight at 120 m.
No matter how much I adjust the alignment settings, a few photos still don't align.
Could someone who has mastered this step give me some advice?
If automated alignment fails, can you manually enter matching points between the photos?
(Attached are a few screenshots to illustrate the problem and the nature of the photos to be processed.)
