mrpt::obs::CObservationIMU Class Reference

Detailed Description

This class stores measurements from an Inertial Measurement Unit (IMU) (attitude estimation, raw gyroscope and accelerometer values), altimeters or magnetometers.

The order of the values in each entry of mrpt::obs::CObservationIMU::rawMeasurements is defined as symbolic names in the enum mrpt::obs::TIMUDataIndex. Check it out also for reference on the unit and the coordinate frame used for each value.

◆ getSensorPose() [1/2]

void CObservation::getSensorPose ( mrpt::math::TPose3D out_sensorPose) const

◆ insertObservationInto()

template<class METRICMAP >
bool mrpt::obs::CObservation::insertObservationInto ( METRICMAP *  theMap,
const mrpt::poses::CPose3D robotPose = nullptr 
) const
inlineinherited

This method is equivalent to:

map->insertObservation(this, robotPose)
Parameters
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()

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.
