Detailed Description

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

PointRepresentation provides a set of methods for converting a point structs/object into an n-dimensional vector.

Note:

This is an abstract class. Subclasses must set nr_dimensions_ to the appropriate value in the constructor and provide an implemention of the pure virtual copyToFloatArray method.

Member Function Documentation

template<typename PointT>

virtual void pcl::PointRepresentation< PointT >::copyToFloatArray	(	const PointT &	p,
		float *	out
	)			const [pure virtual]

Copy point data from input point to a float array. This method must be overriden in all subclasses.

Parameters:

	p	The input point
	out	A pointer to a float array.

Implemented in pcl::DefaultPointRepresentation< PointDefault >, pcl::DefaultPointRepresentation< PointXYZ >, pcl::DefaultPointRepresentation< PointXYZI >, pcl::DefaultPointRepresentation< PointNormal >, pcl::DefaultPointRepresentation< PFHSignature125 >, pcl::DefaultPointRepresentation< FPFHSignature33 >, and MyPointRepresenationXY.

template<typename PointT>

int pcl::PointRepresentation< PointT >::getNumberOfDimensions

(

)

const [inline]

Return the number of dimensions in the point's vector representation.

Definition at line 127 of file point_representation.h.

template<typename PointT>

virtual bool pcl::PointRepresentation< PointT >::isValid

(

const PointT &

p

)

const [inline, virtual]

Verify that the input point is valid.

Parameters:

p

The point to validate

Definition at line 74 of file point_representation.h.

template<typename PointT>

void pcl::PointRepresentation< PointT >::setRescaleValues

(

const float *

rescale_array

)

[inline]

Set the rescale values to use when vectorizing points.

Parameters:

rescale_array

The array/vector of rescale values. Can be of any type that implements the [] operator.

Definition at line 119 of file point_representation.h.

template<typename PointT>

template<typename OutputType >

void pcl::PointRepresentation< PointT >::vectorize	(	const PointT &	p,
		OutputType &	out
	)			const [inline]

Convert input point into a vector representation, rescaling by alpha.

Parameters:

	p
	out	The output vector. Can be of any type that implements the [] operator.
