Member Function Documentation

void sample_consensus::SACModelNormalPlane::getDistancesToModel	(	const std::vector< double > &	model_coefficients,
		std::vector< double > &	distances
	)		`[virtual]`

Compute all distances from the cloud data to a given plane model.

Parameters:

model_coefficients	the coefficients of a plane model that we need to compute distances to
distances	the resultant estimated distances

Reimplemented from sample_consensus::SACModelPlane.

Definition at line 144 of file sac_model_normal_plane.cpp.

virtual int sample_consensus::SACModelNormalPlane::getModelType ( ) [inline, virtual]

Return an unique id for this model (SACMODEL_NORMAL_PLANE).

Reimplemented from sample_consensus::SACModelPlane.

Definition at line 97 of file sac_model_normal_plane.h.

void sample_consensus::SACModelNormalPlane::selectWithinDistance	(	const std::vector< double > &	model_coefficients,
		double	threshold,
		std::vector< int > &	inliers
	)		`[virtual]`

Select all the points which respect the given model coefficients as inliers.

Parameters:

model_coefficients	the coefficients of a plane model that we need to compute distances to
inliers	the resultant model inliers
threshold	a maximum admissible distance threshold for determining the inliers from the outliers

Note:: : To get the refined inliers of a model, use: ANNpoint refined_coeff = refitModel (...); selectWithinDistance (refined_coeff, threshold);

Reimplemented from sample_consensus::SACModelPlane.

Definition at line 58 of file sac_model_normal_plane.cpp.

void sample_consensus::SACModelNormalPlane::setAxis ( const geometry_msgs::Point32 & ax ) [inline]

Set the axis along which we need to search for a plane perpendicular to.

Parameters:

ax	a pointer to the axis.

Definition at line 67 of file sac_model_normal_plane.h.

void sample_consensus::SACModelNormalPlane::setDist ( double d ) [inline]

Set the distance we expect the plane to be from the origin.

Parameters:

d	distance from the template plane to the origin

Definition at line 84 of file sac_model_normal_plane.h.

void sample_consensus::SACModelNormalPlane::setEpsAngle ( double ea ) [inline]

Set the angle epsilon (delta) threshold.

Parameters:

ea	the maximum allowed difference between the plane normal and the given axis

Definition at line 78 of file sac_model_normal_plane.h.

void sample_consensus::SACModelNormalPlane::setEpsDist ( double delta ) [inline]

Set the distance epsilon (delta) threshold.

Parameters:

delta the maximum allowed deviation from the template distance from the origin

Definition at line 90 of file sac_model_normal_plane.h.

void sample_consensus::SACModelNormalPlane::setNormalDistanceWeight ( double w ) [inline]

Set the normal angular distance weight.

Parameters:

w	the relative weight (between 0 and 1) to give to the angular distance (0 to pi/2) between point normals and the plane normal. (The Euclidean distance will have weight 1-w.)
