Constructor & Destructor Documentation

HPIFit() [1/2]

INVERSELIB::HPIFit::HPIFit ( )

explicit

Default constructor.

HPIFit() [2/2]

HPIFit::HPIFit ( const SensorSet &  sensorSet )

explicit

Constructs the HPI from a SensorSet.

Parameters

[in]

SensorSet

The MEG sensorSet used for the hpi fitting.

Definition at line 93 of file hpifit.cpp.

Member Function Documentation

checkForUpdate()

void HPIFit::checkForUpdate

(

const SensorSet &

sensorSet

)

Checks if SensorSet has changed and updates member SensorSet.

Parameters

[in]

SensorSet

The MEG sensorSet used for the hpi fitting.

Definition at line 102 of file hpifit.cpp.

fit()

void INVERSELIB::HPIFit::fit	(	const Eigen::MatrixXd &	matProjectedData,
		const Eigen::MatrixXd &	matProjectors,
		const HpiModelParameters &	hpiModelParameters,
		const Eigen::MatrixXd &	matCoilsHead,
		HpiFitResult &	hpiFitResult
	)

Perform one single HPI fit.

Parameters

[in]	matProjectedData	Data to estimate the HPI positions from. Projectars should be already applied.
[in]	matProjectors	The projectors to apply.
[in]	hpiModelParameters	The model parameters to use for the Hpi Fitting, especially to compute the coil amplitudes.
[in]	matCoilsHead	The hpi coil locations in head space.
[in]	bOrderFrequencies	Order Hpi coils yes/no.
[out]	hpiFitResult	The fitting results.

storeHeadPosition()

void HPIFit::storeHeadPosition ( float  fTime, const Eigen::MatrixXf &  matTransDevHead, Eigen::MatrixXd &  matPosition, const Eigen::VectorXd &  vecGoF, const QVector< double > &  vecError  )

static

Store results from dev_Head_t as quaternions in position matrix. The format is the same as you get from Neuromag's MaxFilter.

Parameters

[in]	fTime	The corresponding time in the measurement for the fit.
[in]	matTransDevHead	The device->head transformation matrix.
[out]	matPosition	The matrix to store the results.
[in]	vecGoF	The goodness of fit per coil.
[in]	vecError	The Hpi estimation Error per coil.

ToDo: get estimated movement velocity and store it in channel 9
