Please @paulinus can you tell me when is gcp used inside the reconstruction ?
Is it absolutely necessary for images to have exif data ?

@btchouston regarding your questions :
- GCP are used through the SfM reconstruction process during bundle adjustment.
- No necessarily, but it will definitely helps and makes the difference between a bad or average reconstruction and a very good one.
