This method is equivalent to:

map->insertObservation(this, robotPose)

Parameters

theMap	The map where this observation is to be inserted: the map will be updated.
robotPose	The pose of the robot base for this observation, relative to the target metric map. Set to nullptr (default) to use (0,0,0deg)

Returns: Returns true if the map has been updated, or false if this observations has nothing to do with a metric map (for example, a sound observation).

◆ load()

virtual void mrpt::obs::CObservation::load ( ) const

inlinevirtualinherited

Makes sure all images and other fields which may be externally stored are loaded in memory.

Note that for all CImages, calling load() is not required since the images will be automatically loaded upon first access, so load() shouldn't be needed to be called in normal cases by the user. If all the data were alredy loaded or this object has no externally stored data fields, calling this method has no effects.
