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.

Constructor & Destructor Documentation

template<typename PointT>
pcl::PointRepresentation< PointT >::PointRepresentation (  )  [inline]

Empty constructor.

Definition at line 62 of file point_representation.h.


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 >, and pcl::DefaultPointRepresentation< FPFHSignature33 >.

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.

Definition at line 96 of file point_representation.h.


Member Data Documentation

template<typename PointT>
