MRPT  1.9.9
mrpt::obs::CObservationPointCloud Class Reference

Detailed Description

An observation from any sensor that can be summarized as a pointcloud.

The cloud can comprise plain XYZ points, or can include intensity, or RGB data; in particular, the point cloud can be any of the derived classes of mrpt::maps::CPointsMap.

The pointcloud has as frame of coordinates the sensorPose field, which may match the origin of the vehicle/robot or not.

Note
This is a mrpt::obs::CObservation class, but it is defined in the mrpt_maps_grp library, so it can use mrpt::maps::CPointsMap.

theMapThe map where this observation is to be inserted: the map will be updated.
robotPoseThe 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()

void CObservationPointCloud::load ( ) const
overridevirtual

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.
