Function Documentation

int accl_mario_orient	(	double *	quat_mario,
		double *	quat
	)

Calculate the transformation to convert from accelerometer's earth-global frame to MARIONET frame of ref.

The function calculates the transformation that converts data in accelerometer system's reference frame (which expresses orientation with respect to the earth-fixed global frame) to the co-ordinates expressed in terms of reference system fixed to the MARIONET.

Parameters:

[in]	quat_mario	Quaternion describing orientation of MARIONET w.r.t earth fixed system
[in,out]	quat	Quaternion describing orientation of acclerometer w.r.t earth fixed system. The function calculates the quaternion w.r.t MARIONET and stores it back here.
