CameraCaliberation example computes NAN

I am using OpenCV 3.0's example project for achieving CameraCalibration. I have a chessboard checker printed which I use to check for a 4 x 6 pattern of checkers.

When I run the program, it computes NAN for (fx and fy) of the CameraMatrix as well as (k1 and k2) of the DistortionCoefficients.

Any advice would be greatly appreciated. Thanks,
