getCurrentlyBuiltMap()

virtual void mrpt::slam::CMetricMapBuilder::getCurrentlyBuiltMap ( CSimpleMap &  out_map ) const

pure virtual

Fills "out_map" with the set of "poses"-"sensory-frames", thus the so far built map.

Implemented in mrpt::slam::CMetricMapBuilderRBPF, and mrpt::slam::CMetricMapBuilderICP.

getCurrentlyBuiltMapSize()

virtual unsigned int mrpt::slam::CMetricMapBuilder::getCurrentlyBuiltMapSize ( )

pure virtual

Returns just how many sensory-frames are stored in the currently build map.

Implemented in mrpt::slam::CMetricMapBuilderRBPF, and mrpt::slam::CMetricMapBuilderICP.

getCurrentlyBuiltMetricMap()

virtual CMultiMetricMap* mrpt::slam::CMetricMapBuilder::getCurrentlyBuiltMetricMap ( )

pure virtual

Returns the map built so far.

NOTE that for efficiency a pointer to the internal object is passed, DO NOT delete nor modify the object in any way, if desired, make a copy of ir with "duplicate()".

Implemented in mrpt::slam::CMetricMapBuilderRBPF, and mrpt::slam::CMetricMapBuilderICP.

getCurrentPoseEstimation()

initialize()

virtual void mrpt::slam::CMetricMapBuilder::initialize ( const CSimpleMap &  initialMap = CSimpleMap(), CPosePDF *  x0 = NULL  )

pure virtual

Initialize the method, starting with a known location PDF "x0"(if supplied, set to NULL to left unmodified) and a given fixed, past map.

Implemented in mrpt::slam::CMetricMapBuilderRBPF, and mrpt::slam::CMetricMapBuilderICP.

leaveCriticalSection()

void mrpt::slam::CMetricMapBuilder::leaveCriticalSection ( )

inlineprotected

Leave critical section for map updating:

printf_debug()

static void mrpt::utils::CDebugOutputCapable::printf_debug ( const char *  frmt,   ...  )

staticinherited

Sends a formated text to "debugOut" if not NULL, or to cout otherwise.

processActionObservation()

virtual void mrpt::slam::CMetricMapBuilder::processActionObservation ( CActionCollection &  action, CSensoryFrame &  observations  )

pure virtual

Parameters

action	The estimation of the incremental pose change in the robot pose.
observations	The set of observations that robot senses at the new pose.

Implemented in mrpt::slam::CMetricMapBuilderRBPF, and mrpt::slam::CMetricMapBuilderICP.

saveCurrentEstimationToImage()

virtual void mrpt::slam::CMetricMapBuilder::saveCurrentEstimationToImage ( const std::string &  file, bool  formatEMF_BMP = true  )

pure virtual

A useful method for debugging: the current map (and/or poses) estimation is dumped to an image file.

Parameters

file	The output file name
formatEMF_BMP	Output format = true:EMF, false:BMP

Implemented in mrpt::slam::CMetricMapBuilderRBPF, and mrpt::slam::CMetricMapBuilderICP.
