Is it possible to set scale and orientation base only on images position without having GCP?

There are more ways how to do scaling - see this Help (F1) tutorial: Scale the Scene…
Hi Lubenko, I checked Help before but I’m still not sure how to do it properly.
In point ‘Scale Using Camera Priors’ it’s sad: ‘Alternatively, camera centers can be known from GPS or flight logs and then the scene will come properly scaled automatically’ and it is exactly what i have - my pictures have information about position (pictures from Phantom 3)
When I export model in local coordinates system scale is absolutely wrong. Is it possible to export model in local coordinates system with a proper scale base only on information about camera position? If yes, I would be extremely great full for print screen with good setting.
Second question - should I set some settings regarding to scale and orientation before alignment? Or it doesn’t matter when?
Thanks,
M.

RealityCapture uses the GPS information automatically, except when you DISABLE it.

Go to WORKFLOW->SETTINGS->COORDINATE SYSTEM and set the proper coordinate system before alignment.

How do you know it is wrong ? Have you measured it in an external application ? Can you post some screenshots so that we can better understand the issue ?

If you have GPS or use laser data, then you do not need to set anything… If they are not present, you need to use GCPs to get the proper scale and orientation…
