The precision of GPS embedded devices in cameras or smartphones is not enough for geopositionning. In the best scenario, GPS precision of this devices is about 3-5 meters. Neither the integrated GPS in a Faro Focus Scanner, only is suitable to do the registration process in Faro SCENE easier.
To georreference a pointcloud, I think that is needed to give coordiantes to at least a point and an orientation (or two points).
Usually the way to do this is setting targets on the field that can be registered by your scanner (or camera) and a total station or GPS that could obtain the "real and accurate" coordinates, and then assign this coordinates to the matching target in ReCap.
Leica C or P scanner series can be stationed on a known point with known coordinates, and then if this point have its coordinates georreferenced, then the point cloud would be georreferenced too.
