template class mrpt::maps::COctoMapBase¶

A three-dimensional probabilistic occupancy grid, implemented as an octo-tree with the “octomap” C++ library.

This base class represents a 3D map where each voxel may contain an “occupancy” property, RGBD data, etc. depending on the derived class.

As with any other mrpt::maps::CMetricMap, you can obtain a 3D representation of the map calling getAs3DObject() or getAsOctoMapVoxels()

To use octomap’s iterators to go through the voxels, use COctoMap::getOctomap()

The octomap library was presented in:

K. M. Wurm, A. Hornung, M. Bennewitz, C. Stachniss, and W. Burgard, “OctoMap: A Probabilistic, Flexible, and Compact 3D Map Representation for Robotic Systems” in Proc. of the ICRA 2010 Workshop on Best Practice in 3D Perception and Modeling for Mobile Manipulation, 2010. Software available at http://octomap.sf.net/.

Construction¶

COctoMapBase(double resolution)

Constructor, defines the resolution of the octomap (length of each voxel side)

Methods¶

virtual void getAsOctoMapVoxels(mrpt::opengl::COctoMapVoxels& gl_obj) const = 0

Builds a renderizable representation of the octomap as a mrpt::opengl::COctoMapVoxels object.
