mrpt::maps::CHeightGridMap2D Class Reference

Detailed Description

Digital Elevation Model (DEM), a mesh or grid representation of a surface which keeps the estimated height for each (x,y) location.

Important implemented features are the insertion of 2D laser scans (from arbitrary 6D poses) and the exportation as 3D scenes.

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

This class implements generic version of mrpt::maps::CMetric::insertObservation() accepting these types of sensory data:

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.

Introduces a pure virtual method responsible for loading from a CStream This can not be used directly be users, instead use "stream >> object;" for reading it from a stream or "stream >> object_ptr;" if the class is unknown apriori.

Parameters
inThe input binary stream where the object data must read from.
versionThe version of the object stored in the stream: use this version number in your code to know how to read the incoming data.
Exceptions
std::exceptionOn any error, see CStream::ReadBuffer

inlineinherited

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.

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
outThe output binary stream where object must be dumped.
getVersionIf NULL, 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.
