Hi
I've not got a 6 chunk model with a total of 1973 images. I have about 400 low accuracy (10m) GPS camera positions (2 chunks) and about 20 high accuracy (5cm) ground control points. I've processed all the chunks (align: high, build geom: med) and I've aligned them all (point based, high). Everything looks pretty good so far.
Now I want to optimise this model. Since I only have 20 GCPs, there are only 2-3 per chunk. Should I merge all the chunks before I optimise? I have 16 gig RAM so according to the Photoscan wiki, I can re-build the geometry on medium just like I already did.
