Large data set Alignment Tips
« on: October 08, 2015, 11:23:57 PM »
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.
