Detailed Description

A 2D grid map representing the reflectivity of the environment (for example, measured with an IR proximity sensor).

Important implemented features are:

Insertion of mrpt::obs::CObservationReflectivity observations.
Probability estimation of observations. See base class.
Rendering as 3D object: a 2D textured plane.
Automatic resizing of the map limits when inserting observations close to the border.

Each cell contains the up-to-date average height from measured falling in that cell. Algorithms that can be used:

mrSimpleAverage: Each cell only stores the current average value.

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.
