Detailed Description

template<typename PointT>
class pcl::ConditionalRemoval< PointT >

ConditionalRemoval filters data that satisfies certain conditions.

A ConditionalRemoval must be provided a condition. There are two types of conditions: ConditionAnd and ConditionOr. Conditions require one or more comparisons and/or other conditions. A comparison has a name, a comparison operator, and a value.

An ConditionAnd will evaluate to true when ALL of its encapsulated comparisons and conditions are true.

An ConditionOr will evaluate to true when ANY of its encapsulated comparisons and conditions are true.

Depending on the derived type of the comparison, the name can correspond to a PointCloud field name, or a color component in rgb color space or hsi color space.

Here is an example usage: // Build the condition pcl::ConditionAnd<PointT>::Ptr range_cond (new pcl::ConditionAnd<PointT> ()); range_cond->addComparison (pcl::FieldComparison<PointT>::Ptr (new pcl::FieldComparison<PointT>("z", pcl::ComparisonOps::LT, 2.0))); range_cond->addComparison (pcl::FieldComparison<PointT>::Ptr (new pcl::FieldComparison<PointT>("z", pcl::ComparisonOps::GT, 0.0))); // Build the filter pcl::ConditionalRemoval<PointT> range_filt; range_filt.setCondition (range_cond); range_filt.setKeepOrganized (false);

Constructor & Destructor Documentation

template<typename PointT>
pcl::ConditionalRemoval< PointT >::ConditionalRemoval ( int  extract_removed_indices = false) [inline]

the default constructor.

All ConditionalRemovals require a condition which can be set using the setCondition method

Parameters:
extract_removed_indicesextract filtered indices from indices vector

Definition at line 599 of file conditional_removal.h.

template<typename PointT>
pcl::ConditionalRemoval< PointT >::ConditionalRemoval ( ConditionBasePtr  condition,
bool  extract_removed_indices = false 
) [inline]

a constructor that includes the condition.

Parameters:
conditionthe condition that each point must satisfy to avoid being removed by the filter
extract_removed_indicesextract filtered indices from indices vector

Definition at line 611 of file conditional_removal.h.


Member Function Documentation

template<typename PointT >
void pcl::ConditionalRemoval< PointT >::applyFilter ( PointCloud output) [protected, virtual]

template<typename PointT >
void pcl::ConditionalRemoval< PointT >::setCondition ( ConditionBasePtr  condition)

Set the condition that the filter will use.

Parameters:
conditioneach point must satisfy this condition to avoid being removed by the filter

All ConditionalRemovals require a condition

Definition at line 663 of file conditional_removal.hpp.

template<typename PointT>
void pcl::ConditionalRemoval< PointT >::setKeepOrganized ( bool  val) [inline]

Set whether the filtered points should be kept and set to the value given through setUserFilterValue (default: NaN), or removed from the PointCloud, thus potentially breaking its organized structure. By default, points are removed.

Parameters:
valset to true whether the filtered points should be kept and set to a given user value (default: NaN)

Definition at line 628 of file conditional_removal.h.

template<typename PointT>
void pcl::ConditionalRemoval< PointT >::setUserFilterValue ( float  val) [inline]

Provide a value that the filtered points should be set to instead of removing them. Used in conjunction with setKeepOrganized ().

Parameters:
valthe user given value that the filtered point dimensions should be set to
