Hi guys , I'm newbi with photo scan so need help .
My problem is that i have 3 aerial photos and want to create point cloud from these photos . In the camera calibration tools i define focal length and pixel size , also i set x y z coordinate  center in gps/ins tab and photoscan create my point cloud .
The problem is the coordinates it gives me is not what they are in real world they are local and the scale not what i need and want calculate some volume , so i can't use these coordinate .
What elese do i need to aquire real world coordinate from photoscan ?
