mrpt::maps::CReflectivityGridMap2D Class Reference

Detailed Description

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

Important implemented features are:

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

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.

Changes the size of the grid, ERASING all previous contents.

If fill_value is left as NULL, the contents of cells may be undefined (some will remain with their old values, the new ones will have the default cell value, but the location of old values may change wrt their old places). If fill_value is not NULL, it is assured that all cells will have a copy of that value after resizing.
