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:

• These three fields are private data member (since MRPT 1.5.0) for safety and to ensure data consistency. Read them with the backwards-compatible proxies scan, intensity, validRange or (preferred) with the new get_*, set_* and resize() methods:
  • CObservation2DRangeScan::scan -> A vector of float values with all the range measurements (in meters).
  • CObservation2DRangeScan::validRange -> A vector (of identical size to scan), has non-zeros for those ranges than are valid (i.e. will be zero for non-reflected rays, etc.)
  • CObservation2DRangeScan::intensity -> A vector (of identical size to scan) a unitless int values representing the relative strength of each return. Higher values indicate a more intense return. This is useful for filtering out low intensity(noisy) returns or detecting intense landmarks.
• CObservation2DRangeScan::aperture -> The field-of-view of the scanner, in radians (typically, M_PI = 180deg).
• CObservation2DRangeScan::sensorPose -> The 6D location of the sensor on the robot reference frame (default=at the origin).

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.

writeToMatlab()

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

inlinevirtualinherited

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.

Definition at line 89 of file CSerializable.h.

writeToStream()

void CObservation2DRangeScan::writeToStream ( mrpt::utils::CStream &  out, int *  getVersion  ) const

overrideprotectedvirtual

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 nullptr, 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.
