mrpt::obs::CObservation2DRangeScan Class Reference

Detailed Description

A "CObservation"-derived class that represents a 2D range scan measurement (typically from a laser scanner).

The data structures are generic enough to hold a wide variety of 2D scanners and "3D" planar rotating 2D lasers.

These are the most important data fields:

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.

◆ swap()

void CObservation::swap ( CObservation o)
protectedinherited

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.

A general method to truncate the scan by defining a minimum valid distance and a maximum valid angle as well as minimun and maximum heights (NOTE: the laser z-coordinate must be provided).

◆ writeToMatlab()

virtual mxArray* mrpt::serialization::CSerializable::writeToMatlab ( ) const

Introduces a pure virtual method responsible for writing to a mxArray Matlab object, typically a MATLAB struct whose contents are documented in each derived class.

Returns
A new mxArray (caller is responsible of memory freeing) or nullptr is class does not support conversion to MATLAB.

◆ deltaPitch

double mrpt::obs::CObservation2DRangeScan::deltaPitch {0}

If the laser gathers data by sweeping in the pitch/elevation angle, this holds the increment in "pitch" (=-"elevation") between the beginning and the end of the scan (the sensorPose member stands for the pose at the beginning of the scan).
