X error (cm) - root mean square error for X coordinate for all the cameras.
Y error (cm) - root mean square error for Y coordinate for all the cameras.
Z error (cm) - root mean square error for Z coordinate for all the cameras.
this three sections contains negative result in GCPs, is that correct?
it is interesting that the total RMSE remain positive result.
another question: Total (cm): 15 and Image (pix): 0.6, is it good result for GCPs?
