Detailed Description

Declares a class that represents any robot's observation.

This is a base class for many types of sensors observations. Users can add a new observation type creating a new class deriving from this one.
IMPORTANT: Observations doesn't include any information about the robot pose beliefs, just the raw observation and, where aplicable, information about sensor position or orientation respect to robotic coordinates origin.

mrpt::slam::CObservation::CObservation ( )

Constructor: It sets the initial timestamp to current time.

Member Function Documentation

static const mrpt::utils::TRuntimeClassId* mrpt::slam::CObservation::_GetBaseClass ( ) [static, protected]

Reimplemented from mrpt::utils::CSerializable.

CObject* mrpt::utils::CObject::clone ( ) const [inline, inherited]

Cloning interface for smart pointers.

Reimplemented in mrpt::opengl::CRenderizable, and mrpt::opengl::CRenderizableDisplayList.

Definition at line 154 of file CObject.h.

virtual CObject* mrpt::utils::CObject::duplicate ( ) const [pure virtual, inherited]

Returns a copy of the object, indepently of its class.

mrpt::utils::CObjectPtr mrpt::utils::CObject::duplicateGetSmartPtr ( ) const [inline, inherited]

Returns a copy of the object, indepently of its class, as a smart pointer (the newly created object will exist as long as any copy of this smart pointer).

Definition at line 151 of file CObject.h.

virtual const mrpt::utils::TRuntimeClassId* mrpt::slam::CObservation::GetRuntimeClass ( ) const [virtual]

Returns information about the class of an object in runtime.

Reimplemented from mrpt::utils::CSerializable.

virtual void mrpt::slam::CObservation::getSensorPose ( CPose3D & out_sensorPose ) const [pure virtual]

A general method to retrieve the sensor pose on the robot.

Note that most sensors will return a full (6D) CPose3D, but see the derived classes for more details or special cases.

See also:: setSensorPose

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

A general method to retrieve the sensor pose on the robot.

Note that most sensors will return a full (6D) CPose3D, but see the derived classes for more details or special cases.

template<class METRICMAP >

bool mrpt::slam::CObservation::insertObservationInto	(	METRICMAP *	theMap,
		const CPose3D *	robotPose = `NULL`
	)		const `[inline]`

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 NULL (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).

Definition at line 122 of file CObservation.h.

virtual void mrpt::slam::CObservation::load ( ) const [inline, virtual]

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.

Reimplemented in mrpt::slam::CObservation3DRangeScan.

Definition at line 159 of file CObservation.h.

virtual void mrpt::utils::CSerializable::readFromStream	(	mrpt::utils::CStream &	in,
		int	version
	)		`[protected, pure virtual, inherited]`

Introduces a pure virtual method responsible for loading from a CStream This can not be used directly be users, instead use "stream >> object;" for reading it from a stream or "stream >> object_ptr;" if the class is unknown apriori.

Parameters:

in	The input binary stream where the object data must read from.
version	The version of the object stored in the stream: use this version number in your code to know how to read the incoming data.

Exceptions:

std::exception On any error, see CStream::ReadBuffer

Implemented in mrpt::math::CMatrixD, and mrpt::math::CMatrix.

virtual void mrpt::slam::CObservation::setSensorPose ( const CPose3D & newSensorPose ) [pure virtual]

A general method to change the sensor pose on the robot.

Note that most sensors will use the full (6D) CPose3D, but see the derived classes for more details or special cases.

void mrpt::slam::CObservation::setSensorPose ( const mrpt::math::TPose3D & newSensorPose )

A general method to change the sensor pose on the robot.

Note that most sensors will use the full (6D) CPose3D, but see the derived classes for more details or special cases.

void mrpt::slam::CObservation::swap ( CObservation & o ) [protected]

Swap with another observation, ONLY the data defined here in the base class CObservation. It's protected since it'll be only called from child classes that should know what else to swap appart from these common data.

virtual void mrpt::slam::CObservation::unload ( ) [inline, virtual]

Unload all images, for the case they being delayed-load images stored in external files (othewise, has no effect).

virtual void mrpt::utils::CSerializable::writeToStream	(	mrpt::utils::CStream &	out,
		int *	getVersion
	)		const `[protected, pure virtual, inherited]`

Introduces a pure virtual method responsible for writing to a CStream.

This can not be used directly be users, instead use "stream << object;" for writing it to a stream.

Parameters:

out	The output binary stream where object must be dumped.
getVersion	If NULL, the object must be dumped. If not, only the version of the object dump must be returned in this pointer. This enables the versioning of objects dumping and backward compatibility with previously stored data.

Exceptions:

std::exception On any error, see CStream::WriteBuffer
