Constructor.

Methods

virtual void processOneLMH(CLocalMetricHypothesis* LMH, const mrpt::obs::CActionCollection::Ptr& act, const mrpt::obs::CSensoryFrame::Ptr& sf) = 0

Main entry point from HMT-SLAM: process some actions & observations.

The passed action/observation will be deleted, so a copy must be made if necessary. This method must be in charge of updating the robot pose estimates and also to update the map when required.

Parameters:

LMH	The local metric hypothesis which must be updated by this SLAM algorithm.
act	The action to process (or nullptr).
sf	The observations to process (or nullptr).

    const mrpt::obs::CSensoryFrame* observation,
    const bayes::CParticleFilter::TParticleFilterOptions& PF_options
    ) = 0

The PF algorithm implementation.
