Meaning of traslations TrX, TrY, TrZ, Tpy, Tpp

[Oswaldo Alejandro Bayona Andrade]

I would like to better understand the meaning of the translation parameters and the projection planes (the wiki information is not enough), because I have georeferenced images and I would like to use the GPS positions to approximate the real values of TrX, TrY, TrZ and Get a better mosaic. Could someone please tell me if there is any way to do this?

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.

Any particular reason for 1.0 being equal to a hectometre?

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