None, you get to choose your own units, Hugin doesn't care what scale you use.

Re: [hugin-ptx] Meaning of traslations TrX, TrY, TrZ, Tpy, Tpp

2017-01-11 Thread 'Bruno Postle' via hugin and other free panoramic software 
These are coordinates relative to the picture plane, TrX and TrY are
parallel to the plane and TrZ is perpendicular. The distance from
0,0,0 to the picture plane is 1.0.

Say you have some drone photos, if the first photo is taken at 100m
altitude you can place it at 0,0,0, if the second photo is taken at
50m altitude then you can place it at 0,0,-0.5.

If TrZ is -1.0 then your drone has crashed.
