Detailed Description

PolarTransformBase implements properties and functionality common to polar transform classes in PCL.

A polar transform remaps pixel values in a two-dimensional image to encode polar coordinates on both image axes. Polar angle measured counter-clockwise with respect to the geometric center of the image is encoded linearly on the vertical (Y) axis. Radial distance to the center is encoded (linearly or not, depending on each particular transform) on the horizontal (X) axis.

Polar transforms have important applications in FFT-based image registration algorithms (e.g. as part of Fourier-Mellin transforms).

Constructor & Destructor Documentation

PolarTransformBase() [1/2]

pcl::PolarTransformBase::PolarTransformBase ( PixelInterpolation &  p )

inline

Constructs a PolarTransformBase object using the specified p pixel interpolation. The referenced interpolation object p must remain valid while this PolarTransformBase object exists.

Definition at line 96 of file PolarTransform.h.

PolarTransformBase() [2/2]

pcl::PolarTransformBase::PolarTransformBase ( const PolarTransformBase &  )

default

Copy constructor.

Member Function Documentation

FinalRotation()

float pcl::PolarTransformBase::FinalRotation ( ) const

inline

Returns the final rotation angle in radians. The default final rotation angle is 2*pi (360 degrees).

Definition at line 129 of file PolarTransform.h.

GetNewSizes()

void pcl::PolarTransformBase::GetNewSizes ( int &  width, int &  height  ) const

inlineoverridevirtual

Predicts transformed image dimensions.

Parameters

[in,out]	width	Reference to a variable whose value is a horizontal dimension in pixels (width). On output, it will receive the predicted horizontal dimension after the transformation.
[in,out]	height	Reference to a variable whose value is a vertical dimension in pixels (height). On output, it will receive the predicted vertical dimension after the transformation.

Note

This is a pure virtual member function that must be reimplemented in every derived class.

Implements pcl::GeometricTransformation.

Definition at line 161 of file PolarTransform.h.

InitialRotation()

float pcl::PolarTransformBase::InitialRotation ( ) const

inline

Returns the initial rotation angle in radians. The default initial rotation angle is zero.

Definition at line 110 of file PolarTransform.h.

SetFinalRotation()

void pcl::PolarTransformBase::SetFinalRotation ( float  angle )

inline

Sets the final rotation angle in radians.

Definition at line 137 of file PolarTransform.h.

References pcl::Swap().

SetInitialRotation()

void pcl::PolarTransformBase::SetInitialRotation ( float  angle )

inline

Sets the initial rotation angle in radians.

Definition at line 118 of file PolarTransform.h.

References pcl::Swap().

SetRotationRange()

void pcl::PolarTransformBase::SetRotationRange ( float  initialAngle, float  finalAngle  )

inline

Sets the initial and final rotation angles, initialAngle and finalAngle respectively, in radians. If the specified initial angle is greater than the final angle, both values are swapped.
