Haha, cool, thanks Götz.
For the GCPS, I’m still confused about what exactly to use. There are those chili tags perhaps? https://github.com/chili-epfl/chilitags
Understood about the “best possible”. We’re using this for a scientific project, quantifying the branching of trees. So, basically, the better we can do, the better. I think your rule of thumb of a dozen pixels of the finest feature is a good one.
Finally, re: distances, I assume the reason for the differing distances is to 1) build the overall structural model that ties everything together at a large distance with lots of overlap between each photo, and 2) capturing detail at closer distances, but not necessarily covering the entire structure… is that about right?
Thanks for your feedback…
