Detailed Description

template<typename ContainerT = OutofcoreOctreeDiskContainer<pcl::PointXYZ>, typename PointT = pcl::PointXYZ>
class pcl::outofcore::OutofcoreOctreeBase< ContainerT, PointT >

This code defines the octree used for point storage at Urban Robotics.

Note
Code was adapted from the Urban Robotics out of core octree implementation. Contact Jacob Schloss jacob.nosp@m..sch.nosp@m.loss@.nosp@m.urba.nosp@m.nrobo.nosp@m.tics.nosp@m..net with any questions. http://www.urbanrobotics.net/. This code was integrated for the Urban Robotics Code Sprint (URCS) by Stephen Fox ( foxst.nosp@m.ephe.nosp@m.nd@gm.nosp@m.ail..nosp@m.com). Additional development notes can be found at http://www.pointclouds.org/blog/urcs/.

The primary purpose of this class is an interface to the recursive traversal (recursion handled by pcl::outofcore::OutofcoreOctreeBaseNode) of the in-memory/top-level octree structure. The metadata in each node can be loaded entirely into main memory, from which the tree can be traversed recursively in this state. This class provides an the interface for:

  1. Point/Region insertion methods
  2. Frustrum/box/region queries
  3. Parameterization of resolution, container type, etc...

For lower-level node access, there is a Depth-First iterator for traversing the trees with direct access to the nodes. This can be used for implementing other algorithms, and other iterators can be written in a similar fashion.

The format of the octree is stored on disk in a hierarchical octree structure, where .oct_idx are the JSON-based node metadata files managed by pcl::outofcore::OutofcoreOctreeNodeMetadata, and .octree is the JSON-based octree metadata file managed by pcl::outofcore::OutofcoreOctreeBaseMetadata. Children of each node live in up to eight subdirectories named from 0 to 7, where a metadata and optionally a pcd file will exist. The PCD files are stored in compressed binary PCD format, containing all of the fields existing in the PCLPointCloud2 objects originally inserted into the out of core object.

A brief outline of the out of core octree can be seen below. The files in [brackets] exist only when the LOD are built.

At this point in time, there is not support for multiple trees existing in a single directory hierarchy.

std::uint64_t pcl::outofcore::OutofcoreOctreeBase< ContainerT, PointT >::addPointCloud_and_genLOD ( pcl::PCLPointCloud2::Ptr & input_cloud )

Recursively add points to the tree.

Recursively add points to the tree. 1/8 of the remaining points at each LOD are stored at each internal node of the octree until either (a) runs out of points, in which case the leaf is not at the maximum depth of the tree, or (b) a larger set of points falls in the leaf at the maximum depth. Note unlike the old implementation, multiple copies of the same point will not be added at multiple LODs as it walks the tree. Once the point is added to the octree, it is no longer propagated further down the tree.

Parameters
[in] input_cloud The input cloud of points which will be copied into the sorted nodes of the out-of-core octree
Returns
The total number of points added to the out-of-core octree.
