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
// Build the filter
range_filt.setCondition (range_cond);
range_filt.setKeepOrganized (false);

setKeepOrganized()

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

setUserFilterValue()

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
val the user given value that the filtered point dimensions should be set to
