2014-11-19 11:59:18 -0600 asked a question Fisheye calibration throws exception

I'm trying to use the fisheye calibration introduced in OpenCV 3.0, and it doesn't seem to work for me. The StereoCalibration throws an exception:

CV_Assert(abs_max < threshold); // bad stereo pair

I looked into the code, and earlier when Calibrate is called, the resulting matrices contain ridiculously high numbers.

Is there any information available on this new method? Anything you need to take into account when aquiring calibration data? What will this method do for lenses that are pretty wide-angle, but not really fish-eye lenses?
