Detailed Description

A class for storing a map of 3D probabilistic landmarks.

Currently these types of landmarks are defined: (see mrpt::maps::CLandmark)

For "visual landmarks" from images: features with associated descriptors.
For laser scanners: each of the range measuremnts, as "occupancy" landmarks.
For grid maps: "Panoramic descriptor" feature points.
For range-only localization and SLAM: Beacons. It is also supported the simulation of expected beacon-to-sensor readings, observation likelihood,...
How to load landmarks from observations:
When invoking CLandmarksMap::insertObservation(), the values in CLandmarksMap::insertionOptions will determinate the kind of landmarks that will be extracted and fused into the map. Supported feature extraction processes are listed next:

Observation class:	Generated Landmarks:	Comments:
CObservationImage	vlSIFT	1) A SIFT feature is created for each SIFT detected in the image, 2) Correspondences between SIFTs features and existing ones are finded by computeMatchingWith3DLandmarks, 3) The corresponding feaures are fused, and the new ones added, with an initial uncertainty according to insertionOptions
CObservationStereoImages	vlSIFT	Each image is separately procesed by the method for CObservationImage observations
CObservationStereoImages	vlColor	TODO...
CObservation2DRangeScan	glOccupancy	A landmark is added for each range in the scan, with its appropiate covariance matrix derived from the jacobians matrixes.

virtualinherited

Computes the matching between this and another 2D point map, which includes finding:

The set of points pairs in each map
The mean squared distance between corresponding pairs.

The algorithm is:

For each point in "otherMap":
- Transform the point according to otherMapPose
- Search with a KD-TREE the closest correspondences in "this" map.
- Add to the set of candidate matchings, if it passes all the thresholds in params.

This method is the most time critical one into ICP-like algorithms.

Parameters

otherMap	[IN] The other map to compute the matching with.
otherMapPose	[IN] The pose of the other map as seen from "this".
params	[IN] Parameters for the determination of pairings.
correspondences	[OUT] The detected matchings pairs.
extraResults	[OUT] Other results.

Parameters

takenFrom	The robot's pose the observation is supposed to be taken from.
obs	The observation.

Returns: This method returns a likelihood value > 0.

[in]	sensorLocationOnRobot	The 3D position of the sensor on the robot
[out]	observations	The results will be stored here.
[in]	sensorDetectsIDs	If this is set to false, all the landmarks will be sensed with INVALID_LANDMARK_ID as ID.

[out]	real_associations	If it's not a NULL pointer, this will contain at the return the real indices of the landmarks in the map in the same order than they appear in out_Observations. Useful when sensorDetectsIDs=false. Spurious readings are assigned a std::string::npos (=-1) index.
[in]	spurious_count_mean	The mean number of spurious measurements (uniformly distributed in range & angle) to generate. The number of spurious is generated by rounding a random Gaussin number. If both this mean and the std are zero (the default) no spurious readings are generated.
[in]	spurious_count_std	Read spurious_count_mean above.

Note: The fields "CObservationBearingRange::fieldOfView_*","CObservationBearingRange::maxSensorDistance" and "CObservationBearingRange::minSensorDistance" MUST BE FILLED OUT before calling this function.; At output, the observation will have CObservationBearingRange::validCovariances set to "false" and the 3 sensor_std_* members correctly set to their values. An observation will be generated for each beacon in the map, but notice that some of them may be missed if out of the sensor maximum range or field of view-
