Detailed Description

template<typename PointT, typename LeafContainerT = OctreePointCloudAdjacencyContainer<PointT>, typename BranchContainerT = OctreeContainerEmpty>
class pcl::octree::OctreePointCloudAdjacency< PointT, LeafContainerT, BranchContainerT >

Octree pointcloud voxel class which maintains adjacency information for its voxels.

This pointcloud octree class generates an octree from a point cloud (zero-copy). The octree pointcloud is initialized with its voxel resolution. Its bounding box is automatically adjusted or can be predefined.

The OctreePointCloudAdjacencyContainer class can be used to store data in leaf nodes.

An optional transform function can be provided which changes how the voxel grid is computed - this can be used to, for example, make voxel bins larger as they increase in distance from the origin (camera).

Note: See SupervoxelClustering for an example of how to provide a transform function.

◆ addPointIdx()

template<typename PointT , typename LeafContainerT , typename BranchContainerT >

void pcl::octree::OctreePointCloudAdjacency< PointT, LeafContainerT, BranchContainerT >::addPointIdx ( uindex_t point_idx_arg )

overrideprotectedvirtual

Add point at index from input pointcloud dataset to octree.

Parameters

[in] point_idx_arg The index representing the point in the dataset given by setInputCloud() to be added

Note: This virtual implementation allows the use of a transform function to compute keys.

Reimplemented from pcl::octree::OctreePointCloud< PointT, OctreePointCloudAdjacencyContainer< PointT >, OctreeContainerEmpty >.

◆ addPointsFromInputCloud()

template<typename PointT , typename LeafContainerT , typename BranchContainerT >

void pcl::octree::OctreePointCloudAdjacency< PointT, LeafContainerT, BranchContainerT >::addPointsFromInputCloud

Adds points from cloud to the octree.

Note: This overrides addPointsFromInputCloud() from the OctreePointCloud class.

protected

Fills in the neighbors fields for new voxels.

Parameters

[in]	key_arg	Key of the voxel to check neighbors for
[in]	leaf_container	Pointer to container of the leaf to check neighbors for

template<typename PointT , typename LeafContainerT , typename BranchContainerT >

void pcl::octree::OctreePointCloudAdjacency< PointT, LeafContainerT, BranchContainerT >::computeVoxelAdjacencyGraph ( VoxelAdjacencyList & voxel_adjacency_graph )

Computes an adjacency graph of voxel relations.

Warning: This slows down rapidly as cloud size increases due to the number of edges.

Parameters

[out] voxel_adjacency_graph Boost Graph Library Adjacency graph of the voxel touching relationships. Vertices are PointT, edges represent touching, and edge lengths are the distance between the points.

Generates octree key for specified point (uses transform if provided).

Parameters

[in]	point_arg	Point to generate key for
[out]	key_arg	Resulting octree key

template<typename PointT , typename LeafContainerT , typename BranchContainerT >

LeafContainerT * pcl::octree::OctreePointCloudAdjacency< PointT, LeafContainerT, BranchContainerT >::getLeafContainerAtPoint ( const PointT & point_arg ) const

Gets the leaf container for a given point.

Parameters

[in] point_arg Point to search for

Returns: Pointer to the leaf container - null if no leaf container found.

◆ setTransformFunction()

template<typename PointT , typename LeafContainerT = OctreePointCloudAdjacencyContainer<PointT>, typename BranchContainerT = OctreeContainerEmpty>

void pcl::octree::OctreePointCloudAdjacency< PointT, LeafContainerT, BranchContainerT >::setTransformFunction ( std::function< void(PointT &p)> transform_func )

inline

Sets a point transform (and inverse) used to transform the space of the input cloud.

This is useful for changing how adjacency is calculated - such as relaxing the adjacency criterion for points further from the camera.

Parameters

[in] transform_func A boost:function pointer to the transform to be used. The transform must have one parameter (a point) which it modifies in place.

		const PointXYZ &	camera_pos = `PointXYZ(0, 0, 0)`
	)

Tests whether input point is occluded from specified camera point by other voxels.

Parameters

[in]	point_arg	Point to test for
[in]	camera_pos	Position of camera, defaults to origin

Returns: True if path to camera is blocked by a voxel, false otherwise.
