void FittingCurve2dSDM::addPointConstraint	(	const double &	param,
		const Eigen::Vector2d &	point,
		const Eigen::Vector2d &	normal,
		const Eigen::Vector2d &	tangent,
		double	rho,
		double	d,
		double	weight,
		unsigned &	row
	)		`[protected, virtual]`

Add minimization constraint: point-to-surface distance (squared-distance-minimization).

Definition at line 142 of file fitting_curve_2d_sdm.cpp.

void FittingCurve2dSDM::assemble ( const Parameter & parameter ) [virtual]

Assemble the system of equations for fitting.

for large point-clouds this is time consuming.
should be done once before refinement to initialize the starting points for point inversion.

Reimplemented from pcl::on_nurbs::FittingCurve2dPDM.

Definition at line 57 of file fitting_curve_2d_sdm.cpp.

void FittingCurve2dSDM::assembleInterior	(	double	wInt,
		double	rScale,
		unsigned &	row
	)		`[protected, virtual]`

Assemble point-to-surface constraints.

Reimplemented from pcl::on_nurbs::FittingCurve2dPDM.

Definition at line 212 of file fitting_curve_2d_sdm.cpp.

double FittingCurve2dSDM::solve ( double damp = 1.0 ) [virtual]

Solve system of equations using Eigen or UmfPack (can be defined in on_nurbs.cmake), and updates B-Spline curve if a solution can be obtained.

Reimplemented from pcl::on_nurbs::FittingCurve2dPDM.

Definition at line 89 of file fitting_curve_2d_sdm.cpp.

double FittingCurve2dSDM::updateCurve ( double damp ) [virtual]

Update curve according to the current system of equations.

Parameters:

[in] damp damping factor from one iteration to the other.

Reimplemented from pcl::on_nurbs::FittingCurve2dPDM.
