class mrpt::obs::CObservationRFID

This represents one or more RFID tags observed by a receiver.

See also:

CObservation, mrpt::hwdrivers::CImpinjRFID for a software sensor capable of reading this kind of observations.

Fields

mrpt::poses::CPose3D sensorPoseOnRobot

The location of the sensing antenna on the robot coordinate framework.

std::vector<TTagReading> tag_readings

The vector of individual tag observations.

Construction

CObservationRFID()

Constructor.

Methods

virtual void getSensorPose(mrpt::poses::CPose3D& 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.
