Fisheye calibration gives a wrong parameters

When I use the fisheye model to calibrate my camera,the error is more than 200 pixels.And I use the three elevation calibration plates to do this.When I reduce the corners of the boundary,it can work and get a small error.But if the parameter is getted without the corners of the boundary,the distortion can't be rectified very well.So what can I do with this?

I change the fuction that computes Mat H,this can help to get a almost right initExtrinsics.But I find another problem that the error is about 3 pixels.I think the optimization algorithm is not good for the three elevation calibration.So is any suggestion?
