I have about a 1000 aerial photos taken with a UAV at about 50m AGL in a near nadir view. The photos do not have geo-referencing. I am having trouble with alignment. There are some large areas (100 photos or so) that do not align. As this is a large dataset, I don't want to have to run the project trying various settings as it will take a long time on my computer. Can you recommend what alignment settings would be best to have the best chance of initial alignment.
Which settings would you recommend:
Accuracy: high, medium or low ( I set medium)
Pair Selection: generic, pair selection or reference (I set generic)
Key Point limit: default (40000 I think)
Tie point limit: default (1000 I think)
And are there any other tricks to help obtain an alignment? For example can you manually set tie points to help alignment? etc.
