Detailed Description

CorrespondenceRejectorFeatures implements a correspondence rejection method based on a set of feature descriptors.

Given an input feature space, the method checks if each feature in the source cloud has a correspondence in the target cloud, either by checking the first K (given) point correspondences, or by defining a tolerance threshold via a radius in feature space.

Todo:
explain this better.

Member Function Documentation

applyRejection()

void pcl::registration::CorrespondenceRejectorFeatures::applyRejection ( pcl::Correspondences & correspondences )
inlineoverrideprotectedvirtual

Apply the rejection algorithm.

Parameters
[out] correspondences the set of resultant correspondences.

Implements pcl::registration::CorrespondenceRejector.

Definition at line 151 of file correspondence_rejection_features.h.

getRemainingCorrespondences()

void pcl::registration::CorrespondenceRejectorFeatures::getRemainingCorrespondences ( const pcl::Correspondences & original_correspondences,
pcl::Correspondences & remaining_correspondences
)
overridevirtual

Get a list of valid correspondences after rejection from the original set of correspondences.

Parameters
[in] original_correspondences the set of initial correspondences given
[out] remaining_correspondences the resultant filtered set of remaining correspondences

Implements pcl::registration::CorrespondenceRejector.

getSourceFeature()

template<typename FeatureT >
pcl::PointCloud< FeatureT >::ConstPtr pcl::registration::CorrespondenceRejectorFeatures::getSourceFeature ( const std::string & key )
inline

Get a pointer to the source cloud's feature descriptors, specified by the given key.

Parameters
[in] key a string that uniquely identifies the feature (must match the key provided by setSourceFeature)

Definition at line 64 of file correspondence_rejection_features.hpp.

getTargetFeature()

template<typename FeatureT >
pcl::PointCloud< FeatureT >::ConstPtr pcl::registration::CorrespondenceRejectorFeatures::getTargetFeature ( const std::string & key )
inline

Get a pointer to the source cloud's feature descriptors, specified by the given key.

Parameters
[in] key a string that uniquely identifies the feature (must match the key provided by setTargetFeature)

Definition at line 86 of file correspondence_rejection_features.hpp.

References features_map_.

hasValidFeatures()

bool pcl::registration::CorrespondenceRejectorFeatures::hasValidFeatures ( )
inline

Test that all features are valid (i.e., does each key have a valid source cloud, target cloud, and search method)

setDistanceThreshold()

template<typename FeatureT >
void pcl::registration::CorrespondenceRejectorFeatures::setDistanceThreshold ( double thresh,
const std::string & key
)
inline

Set a hard distance threshold in the feature FeatureT space, between source and target features.

Any feature correspondence that is above this threshold will be considered bad and will be filtered out.

Parameters
[in] thresh the distance threshold
[in] key a string that uniquely identifies the feature

Provide a boost shared pointer to a PointRepresentation to be used when comparing features.

Parameters
[in] key a string that uniquely identifies the feature
[in] fr the point feature representation to be used

Definition at line 107 of file correspondence_rejection_features.hpp.

void pcl::registration::CorrespondenceRejectorFeatures::setSourceFeature ( const typename pcl::PointCloud< FeatureT >::ConstPtr & source_feature,
const std::string & key
)
inline

Provide a pointer to a cloud of feature descriptors associated with the source point cloud.

Parameters
[in] source_feature a cloud of feature descriptors associated with the source point cloud
[in] key a string that uniquely identifies the feature

setTargetFeature()

template<typename FeatureT >
void pcl::registration::CorrespondenceRejectorFeatures::setTargetFeature ( const typename pcl::PointCloud< FeatureT >::ConstPtr & target_feature,
const std::string & key
)
inline

Provide a pointer to a cloud of feature descriptors associated with the target point cloud.

Parameters
[in] target_feature a cloud of feature descriptors associated with the target point cloud
[in] key a string that uniquely identifies the feature

Member Data Documentation

features_map_

FeaturesMap pcl::registration::CorrespondenceRejectorFeatures::features_map_
protected

An STL map containing features to use when performing the correspondence search.

Definition at line 180 of file correspondence_rejection_features.h.

Referenced by getSourceFeature(), getTargetFeature(), setDistanceThreshold(), setFeatureRepresentation(), setSourceFeature(), and setTargetFeature().

max_distance_

float pcl::registration::CorrespondenceRejectorFeatures::max_distance_
protected

The maximum distance threshold between two correspondent points in source <-> target.

If the distance is larger than this threshold, the points will not be ignored in the alignment process.
