I think focal lengtn(f_x, f_y) is Unique value so always get same value.....maybe is my idea wrong? and i think principal points(c_x, c_y) are value of my image(value of my imshow size). this is right idea? help me....
how exactly are you doing the calibration ? what is the the rms from that ?
as long as your results differ that much, you're probably doing something wrong there
I think so...can you help me ?
there is my git and that is my src...can you check?
if possible I'd appreciate your help
