Expand description

Distorts 2D points using fisheye model.

Parameters

undistorted: Array of object points, 1xN/Nx1 2-channel (or vector<Point2f> ), where N is the number of points in the view.
K: Camera intrinsic matrix $inline formula$ .
D: Input vector of distortion coefficients $inline formula$ .
alpha: The skew coefficient.
distorted: Output array of image points, 1xN/Nx1 2-channel, or vector<Point2f> .

Note that the function assumes the camera intrinsic matrix of the undistorted points to be identity. This means if you want to transform back points undistorted with #fisheye::undistortPoints you have to multiply them with $inline formula$ .
