Member Function Documentation

computeSSOBetweenObservations()

virtual bool mrpt::hmtslam::CTopLCDetectorBase::computeSSOBetweenObservations ( const THypothesisID &  hypID, const TPoseID &  poseID1, const TPoseID &  poseID2, double &  out_SSO  )

inlinevirtualinherited

If implemented, this method provides the evaluation of an additional term to be added to the SSO between each pair of observations.

Parameters

out_SSO

The output, in the range [0,1].

Returns

true if computed SSO is meaningful. The default virtual method returns false.

Definition at line 61 of file CTopLCDetectorBase.h.

References MRPT_UNUSED_PARAM.

computeTopologicalObservationModel()

CPose3DPDF::Ptr CTopLCDetector_FabMap::computeTopologicalObservationModel ( const THypothesisID &  hypID, const CHMHMapNode::Ptr &  currentArea, const CHMHMapNode::Ptr &  refArea, double &  out_log_lik  )

virtual

This method must compute the topological observation model.

Parameters

out_log_lik

The output, a log-likelihood.

Returns

nullptr (empty smart pointer), or a PDF of the estimated translation between the two areas (can be a multi-modal PDF).

Parameters

out_log_lik

The output, a log-likelihood.

Returns

nullptr, or a PDF of the estimated translation between the two areas (can be a multi-modal PDF).

Implements mrpt::hmtslam::CTopLCDetectorBase.

createNewInstance()

static CTopLCDetectorBase* mrpt::hmtslam::CTopLCDetector_FabMap::createNewInstance ( CHMTSLAM *  hmtslam )

inlinestatic

A class factory, to be implemented in derived classes.

References CTopLCDetector_FabMap().

OnNewPose()

void CTopLCDetector_FabMap::OnNewPose ( const TPoseID &  poseID, const mrpt::obs::CSensoryFrame *  SF  )

virtual

Hook method for being warned about the insertion of a new poses into the maps.

This should be independent of hypothesis IDs.

Reimplemented from mrpt::hmtslam::CTopLCDetectorBase.

Definition at line 78 of file CTopLCDetector_FabMap.cpp.

References mrpt::obs::CSensoryFrame::getObservationByClass(), and MRPT_UNUSED_PARAM.

reset()

virtual void mrpt::hmtslam::CTopLCDetectorBase::reset ( )

inlinevirtualinherited

Reset the internal state of the TLCD, if any.

This is needed since the objects are created while loading HMT-SLAM options, but the algorithm may be re-started after that at any time.
