Detailed Description

A class for interfacing Inertial Measuring Units (IMUs) of the type "XSens MTi" It uses a serial port connection to the device.

The class implements the generic See also the application "rawlog-grabber" for a ready-to-use application to gather data from the scanner.

void mrpt::hwdrivers::CGenericSensor::appendObservation ( const mrpt::utils::CSerializablePtr & obj )

inlineprotectedinherited

Like appendObservations() but for just one observation.

Definition at line 155 of file CGenericSensor.h.

void mrpt::hwdrivers::CGenericSensor::appendObservations ( const std::vector< mrpt::utils::CSerializablePtr > & obj )

protectedinherited

This method must be called by derived classes to enqueue a new observation in the list to be returned by getObservations.

Passed objects must be created in dynamic memory and a smart pointer passed. Example of creation:

CObservationGPSPtr  o = CObservationGPSPtr( new CObservationGPS() );
o-> .... // Set data
appendObservation(o);

If several observations are passed at once in the vector, they'll be considered as a block regarding the grabbing decimation factor.

static CGenericSensor* mrpt::hwdrivers::CGenericSensor::createSensor ( const std::string & className )

staticinherited

Creates a sensor by a name of the class.

Typically the user may want to create a smart pointer around the returned pointer, whis is made with:

CGenericSensorPtr sensor = CGenericSensorPtr( CGenericSensor::createSensor("XXX") );

Returns: A pointer to a new class, or NULL if class name is unknown.

static CGenericSensorPtr mrpt::hwdrivers::CGenericSensor::createSensorPtr ( const std::string & className )

inlinevirtualinherited

Set the path where to save off-rawlog image files (will be ignored in those sensors where this is not applicable).

An empty string (the default value at construction) means to save images embedded in the rawlog, instead of on separate files.

std::exception If the directory doesn't exists and cannot be created.
