class mrpt::poses::CPose3DPDF

A Probability Density Function (PDF) of a SE(3) pose.

This class is just the base class for unifying many diferent ways this PDF can be implemented.

For convenience, a pose composition is also defined for any PDF derived class, changeCoordinatesReference, in the form of a method rather than an operator.

For a similar class for 3D points (without attitude), see CPointPDF

See also the tutorial on probabilistic spatial representations in the MRPT.

Methods

virtual void copyFrom(const CPose3DPDF& o) = 0

Copy operator, translating if necesary (for example, between particles and gaussian representations)

createFrom2D

virtual void bayesianFusion(const CPose3DPDF& p1, const CPose3DPDF& p2) = 0

Bayesian fusion of two pose distributions, then save the result in this object (WARNING: Currently only distributions of the same class can be fused! eg, gaussian with gaussian,etc)

virtual void inverse(CPose3DPDF& o) const = 0

Returns a new PDF such as: NEW_PDF = (0,0,0) - THIS_PDF.
