Detailed Description

Representation of the range based detector. The class represents the range based detector defined in the paper. It extracts blobs (extrema of the second derivative) on the range signal. This is equivalent of applying the theory behind the SIFT detector on the monodimensional range image.

Constructor & Destructor Documentation

RangeDetector::RangeDetector ( const PeakFinder peak,
unsigned int  scales = 5,
double  sigma = 1.6,
double  step = 1.4,
SmoothingFilterFamily  filterType = BESSEL 
)

Constructor. Constructs and initialize the range based detector.

Parameters:
peak The peak finder used to detect maxima in the signal.
scales The number of different scales to consider.
sigma The standard deviation of the smoothing kernel for the initial scale ($ t_0 $ in the paper).
step The scale increment at every new scale ($ t_i $ in the paper). The standard deviation of the kernel at scale $ s $ is $ t_0 \cdot (t_i)^s $
filterType The smoothing kernel used in the detector.

Member Function Documentation

void RangeDetector::computeDifferentialBank (  )  [protected, virtual]

Computes the bank for the second derivative at different scales.

Implements MultiScaleDetector.

unsigned int RangeDetector::computeInterestPoints ( const LaserReading reading,
const std::vector< double > &  signal,
std::vector< InterestPoint * > &  point,
std::vector< std::vector< unsigned int > > &  indexes,
std::vector< unsigned int > &  maxRangeMapping 
) const [protected, virtual]

Computes the interst point locations and (when possible) orientation. The points are extracted from the laser reading according to the indexes.

Implements MultiScaleDetector.

void RangeDetector::computeSignal ( const LaserReading reading,
std::vector< double > &  signal,
std::vector< unsigned int > &  maxRangeMapping 
) const [protected, virtual]

Computes the monodimensional signal from which extracts the features.

Implements MultiScaleDetector.
