Constructor & Destructor Documentation

◆ ModelLibrary()

pcl::recognition::ModelLibrary::ModelLibrary	(	float	pair_width,
		float	voxel_size,
		float	max_coplanarity_angle = 3.0f *AUX_DEG_TO_RADIANS )

This class is used by 'ObjRecRANSAC' to maintain the object models to be recognized.

Normally, you do not need to use this class directly.

◆ ~ModelLibrary()

virtual pcl::recognition::ModelLibrary::~ModelLibrary ( )

inlinevirtual

Member Function Documentation

◆ addModel()

bool pcl::recognition::ModelLibrary::addModel	(	const PointCloudIn &	points,
		const PointCloudN &	normals,
		const std::string &	object_name,
		float	frac_of_points_for_registration,
		void *	user_data = nullptr )

Adds a model to the hash table.

Parameters

[in]	points	represents the model to be added.
[in]	normals	are the normals at the model points.
[in]	object_name	is the unique name of the object to be added.
[in]	frac_of_points_for_registration	is the number of points used for fast ICP registration prior to hypothesis testing
[in]	user_data	is a pointer to some data (can be NULL)

Returns true if model successfully added and false otherwise (e.g., if object_name is not unique).

◆ addToHashTable()

bool pcl::recognition::ModelLibrary::addToHashTable	(	Model *	model,
		const ORROctree::Node::Data *	data1,
		const ORROctree::Node::Data *	data2 )

protected

Returns true if the oriented point pair was added to the hash table and false otherwise.

◆ clear()

void pcl::recognition::ModelLibrary::clear ( )

protected

Removes all models from the library and destroys the hash table.

This method should be called upon destroying this object.

Referenced by ~ModelLibrary().

◆ getHashTable()

const HashTable & pcl::recognition::ModelLibrary::getHashTable ( ) const

inline

Returns the hash table built by this instance.

Definition at line 227 of file model_library.h.

References hash_table_.

◆ getModel()

const Model * pcl::recognition::ModelLibrary::getModel ( const std::string & name ) const

inline

Definition at line 233 of file model_library.h.

References models_.

◆ getModels()

const std::map< std::string, Model * > & pcl::recognition::ModelLibrary::getModels ( ) const

inline

Definition at line 243 of file model_library.h.

References models_.

◆ ignoreCoplanarPointPairsOff()

void pcl::recognition::ModelLibrary::ignoreCoplanarPointPairsOff ( )

inline

Call this method in order to add all point pairs (co-planar as well) to the hash table.

The default behavior is ignoring co-planar points on.

Definition at line 207 of file model_library.h.

References ignore_coplanar_opps_.

◆ ignoreCoplanarPointPairsOn()

void pcl::recognition::ModelLibrary::ignoreCoplanarPointPairsOn ( )

inline

Call this method in order NOT to add co-planar point pairs to the hash table.

The default behavior is ignoring co-planar points on.

Definition at line 199 of file model_library.h.

References ignore_coplanar_opps_.

◆ removeAllModels()

void pcl::recognition::ModelLibrary::removeAllModels ( )

Removes all models from the library and clears the hash table.

◆ setMaxCoplanarityAngleDegrees()

void pcl::recognition::ModelLibrary::setMaxCoplanarityAngleDegrees ( float max_coplanarity_angle_degrees )

inline

This is a threshold.

The larger the value the more point pairs will be considered as co-planar and will be ignored in the off-line model pre-processing and in the online recognition phases. This makes sense only if "ignore co-planar points" is on. Call this method before calling addModel.
