class mrpt::poses::CPose3DPDFParticles

Overview

Declares a class that represents a Probability Density function (PDF) of a 3D pose.

This class is also the base for the implementation of Monte-Carlo Localization (MCL), in mrpt::slam::CMonteCarloLocalization2D.

See the application “app/pf-localization” for an example of usage.
