https://docs.opencv.org/2.4/doc/tutor... I saw the equation here, in the first 2 equations X_corrected and Y_corrected value can be huge!

I tried to use the OpenCV sample file for camera calibration and using the obtained distortion vector to correct a pixel position. it corrected 1230,760 to something close to 10e20.

Did I make a mistake about the input value of this equation? In another word, what is the x and y value in this equation?

Thank you

x and y are distorted pixel coordinates.

And the p values are usually reallly small.
