[Rtk-users] Simulating geometric error on detector

[김창환]

Dear all,

I am now generating the simulation data with geometric distortions on the
detector, by using RTK.

Translation can be easily implemented by adjusting the parameters
(proj_iso_x and proj_iso_y).
However, for the rotation, it seems that there are only two parameters I
can manage. (in_angle and out_angle).
Thus, at this moment, tilt and skew are available to implement, but for the
slant, it seems that there is no such way.

Please let me know if there is any way to implement rotation about one
other axis.
