If you want to export control points and then use them as GCP, copy the example from attached link, then go to C:\Program Files\Capturing Reality\RealityCapture and open the controlpoints.xml file. And replace the 43rd line with this. You can also use it as separate option, but then you need to change formatID and descID to have exceptional IDs.
If you do so, you will be able to export coordinates of your control point, which will be the same in next model processes and therefore all created models will be in the same coordinate system and basically oriented (if the model won’t change its position).
