General / What units PS use for distortion parameters?
« on: June 12, 2011, 07:36:49 PM »
Hi,
I have a guestion, what units use PS for distortion parameters.
More preciselly, what units are used for radial and tangencial distortion parameters because it seems clear fx, fy, cx, cy are stated in pixels.
For k1, .., k3 are usually use (mm^-2,mm^-4,mm^-6) or (pixel^-2,pixel^-4,pixel^-6) but it is not the case of PS.
I would like to use calibration parameters from PhotoModeler (where mm are used) and I'm not sure about conversion.
Thanks
