mrpt::slam::CGridMapAligner Class Reference

Detailed Description

A class for aligning two multi-metric maps (with an occupancy grid maps and a points map, at least) based on features extraction and matching.

The matching pose is returned as a Sum of Gaussians (poses::CPosePDFSOG).

This class can use three methods (see options.methodSelection):

  • amCorrelation: "Brute-force" correlation of the two maps over a 2D+orientation grid of possible 2D poses.
  • amRobustMatch: Detection of features + RANSAC matching
  • amModifiedRANSAC: Detection of features + modified multi-hypothesis RANSAC matching as described in was reported in the paper http://www.mrpt.org/Paper%3AOccupancy_Grid_Matching

See CGridMapAligner::Align for more instructions.

◆ Align()

CPosePDF::Ptr CMetricMapsAlignmentAlgorithm::Align ( const mrpt::maps::CMetricMap m1,
const mrpt::maps::CMetricMap m2,
const mrpt::poses::CPose2D grossEst,
float *  runningTime = nullptr,
void info = nullptr 
)
inherited

The method for aligning a pair of metric maps, aligning only 2D + orientation.

The meaning of some parameters and the kind of the maps to be aligned are implementation dependant, so look into the derived classes for instructions. The target is to find a PDF for the pose displacement between maps, thus the pose of m2 relative to m1. This pose is returned as a PDF rather than a single value.

Parameters
m1[IN] The first map
m2[IN] The second map. The pose of this map respect to m1 is to be estimated.
grossEst[IN] An initial gross estimation for the displacement. If a given algorithm doesn't need it, set to CPose2D(0,0,0) for example.
runningTime[OUT] A pointer to a container for obtaining the algorithm running time in seconds, or nullptr if you don't need it.
info[OUT] See derived classes for details, or nullptr if it isn't needed.
Returns
A smart pointer to the output estimated pose PDF.

◆ AlignPDF()

CPosePDF::Ptr CGridMapAligner::AlignPDF ( const mrpt::maps::CMetricMap m1,
const mrpt::maps::CMetricMap m2,
const mrpt::poses::CPosePDFGaussian initialEstimationPDF,
float *  runningTime = nullptr,
void info = nullptr 
)
virtual

The method for aligning a pair of 2D points map.

The meaning of some parameters are implementation dependant, so look for derived classes for instructions. The target is to find a PDF for the pose displacement between maps, thus the pose of m2 relative to m1. This pose is returned as a PDF rather than a single value.

NOTE: This method can be configurated with "options"

Parameters
m1[IN] The first map (Must be a mrpt::maps::CMultiMetricMap class)
m2[IN] The second map (Must be a mrpt::maps::CMultiMetricMap class)
initialEstimationPDF[IN] (IGNORED IN THIS ALGORITHM!)
runningTime[OUT] A pointer to a container for obtaining the algorithm running time in seconds, or NULL if you don't need it.
info[OUT] A pointer to a TReturnInfo struct, or NULL if result information are not required.
Note
The returned PDF depends on the selected alignment method:
  • "amRobustMatch" –> A "poses::CPosePDFSOG" object.
  • "amCorrelation" –> A "poses::CPosePDFGrid" object.
Returns
A smart pointer to the output estimated pose PDF.
