initUndistortRectifyMap function

(Mat, Mat) initUndistortRectifyMap(
  1. InputArray cameraMatrix,
  2. InputArray distCoeffs,
  3. InputArray R,
  4. InputArray newCameraMatrix,
  5. (int, int) size,
  6. int m1type, {
  7. OutputArray? map1,
  8. OutputArray? map2,
})

InitUndistortRectifyMap computes the joint undistortion and rectification transformation and represents the result in the form of maps for remap
