class mrpt::obs::CObservationRange

Declares a class derived from “CObservation” that encapsules a single range measurement, and associated parameters.

This can be used for example to store measurements from infrared proximity sensors (IR) or ultrasonic sensors (sonars).

Fields

float minSensorDistance {0}

The data members.

float sensorConeAperture = mrpt::d2f(20.0_deg)

Cone aperture of each ultrasonic beam, in radians.

TMeasurementList sensedData

All the measurements.

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.
