Undistorts 2D points using fisheye model

undistorted = cv.fisheyeUndistortPoints(distorted, K, D);
[...] = cv.fisheyeUndistortPoints(..., 'OptionName',optionValue, ...);

Input

• distorted Object points. An Nx2, 1xNx2, or Nx1x2 array, where N is the number of points in the view.
• K Camera matrix 3x3, K = [fx 0 cx; 0 fy cy; 0 0 1].
• D Input vector of distortion coefficients [k1,k2,k3,k4].

Output

• undistorted Output array of image points.

Options

• R Rectification transformation in the object space (3x3 matrix or 1x3/3x1 vector).
• P New camera matrix (3x3) or new projection matrix (3x4).
