Hi there,

I've used ImageMagick to calibrate my camera and obtain the a,b,c lens distortion parameters. How do I convert these a,b,c parameters to OpenCV style (k1,k2,p1,p2...)?

Best approach is to use opencv to calibrate your camera. If you want absolutely use imagemagick parameter and convert to opencv model you have to use matlab like software(scilab octave mathematica....) to adjust model parameter....

Yes, that is the best solution, but I just want to avoid the tediousness of a new calibration in OpenCV. Anyway I guess I'll have to do it sooner or later... Thanks.

I've found the relation here:

  • a = k2 * (width/2) ^ 3
  • b = 0
  • c = k1 * (width/2)
  • d = 1
