Thanks, I´ll do it.
While I was searching I read this (Extracted from: Agisoft photoscan pro_1_4_en):
"In the Reference preselection mode the overlapping pairs of photos are selected based on the
measured camera locations (if present). For oblique imagery it is necessary to set Ground altitude
value (average ground height in the same coordinate system which is set for camera coordinates data)
in the Settings dialog of the Reference pane to make the preselection procedure work efficiently.
Ground altitude information must be accompanied with yaw, pitch, roll data for cameras. Yaw, pitch,
roll data should be input in the Reference pane.
You can switch on both options to speed up the processing even more."
Can you explain me the bolded part please.
Thank you in advance.
