UndistortPoints odd results

Hi all, I've calibrated my camera and here is the distortion parameters: [ 7.0576386285112147e-02, -5.0734456409579369e+00,-1.1508247483618957e-02, -3.9730820350519589e-03, 8.0251688016585078e+01 ]

My problem is that when undistort a point (552,320) , I get (0.146645,-0.104564 ). What can be the cause of this? How can I get undistorted point in pixel coordinates for example (560,315) ?

You see the last parameter of undistortPoints? P?

Put your camera matrix into that parameter as well, otherwise it uses a default identity matrix.
