camera lens distortion correction

rw55 — Mon, 26 Feb 2007 16:37:21 GMT

Hi all,

the function:

ippiCreateMapCameraUndistort_32f_C1R

should create an "undistortion map" usingradial and tangential distortion coefficients, and focal lengths.

How do i use those parameters?

what is the effect of each one of them on the output image?

Thanks.

Hi,

The output of function are images pxMap and pyMap containing undistorted x and y coordinated.

These arrays can be used by ippiRemap function to correct distortion. the interpolation type is an argument of ippRemap.

Thanks,

Alexander
