void argUtilCalibHMD	(	int	targetId,
		int	thresh2,
		void(*)(ARParam *lpara, ARParam *rpara)	postFunc
	)

utility function for calibrate an HMD.

This function offers a full calibration run-time routines for an optical HMD (mono or stereo). It is useful for estimate transformation between user eye position and camera position. You will find more informations on the calibration routine on opticalcalibration.html .This function modify gsub state of left and right camera intrinsic parameters.

Parameters:

targetId	the target used for the calibration step.
thresh2	lighting threshold value to use
postFunc	a callback function used to analysis computed internal camera parameters. if your application is mono display, only lpara contains a value. lpara and rpara are NULL if the calibration failed.
