class mrpt::maps::CLandmarksMap

Overview

A minimal landmarks map: a container of CLandmark objects.

This is a simplified version for MRPT v3.0, retaining only the functionality needed and removing the computer vision part.

Typedefs

typedef std::shared_ptr<mrpt::maps ::CLandmarksMap> Ptr

A type for the associated smart pointer.

Methods

virtual const mrpt::rtti::TRuntimeClassId* GetRuntimeClass() const

Returns information about the class of an object in runtime.

virtual mrpt::rtti::CObject* clone() const

Returns a deep copy (clone) of the object, indepently of its class.

void simulateRangeBearingReadings(
    const mrpt::poses::CPose3D& robotPose,
    const mrpt::poses::CPose3D& sensorOnRobot,
    mrpt::obs::CObservationBearingRange& obs,
    bool sensorDistinguishesLandmarks = true,
    double sigmaRange = 0,
    double sigmaYaw = 0,
    double sigmaPitch = 0,
    std::vector<size_t>* out_indices = nullptr,
    double spuriousMean = 0,
    double spuriousStd = 0
    ) const

Simulate a range-bearing sensor observation from this landmark map.

Parameters:

robotPose	Global pose of the robot.
sensorOnRobot	Pose of the sensor relative to the robot.
obs	Output observation (sensedData will be filled). obs.fieldOfView_yaw, maxSensorDistance, minSensorDistance must be set by the caller.
sensorDistinguishesLandmarks	If true, each observation has the actual landmark ID; if false, they are all set to -1.
sigmaRange	Noise standard deviation for range (meters).
sigmaYaw	Noise standard deviation for yaw (radians).
sigmaPitch	Noise standard deviation for pitch (radians, use 0 for 2D).
out_indices	If non-null, stores the GT landmark index for each observation; spurious detections get index std::string::npos.
spuriousMean	Mean number of spurious detections.
spuriousStd	Std of the number of spurious detections.

virtual bool isEmpty() const

Returns true if the map is empty/no observation has been inserted.

virtual std::string asString() const

Returns a human-friendly textual description of the object.

For classes with a large/complex internal state, only a summary should be returned instead of the exhaustive enumeration of all data members.

virtual void getVisualizationInto(mrpt::viz::CSetOfObjects& o) const

Inserts 3D primitives representing this object into the provided container.

Note that the former contents of o are not cleared.
