Connected-Component Labeling
Description
Assigns an ID to each cluster of connected components in a point cloud. The point cloud is subdivided
into a 3D grid, and a classical Connected-Component Labeling algorithm is applied in 3D.
Usage
connected_components(las, res, min_pts, name = "clusterID", connectivity = 6)
Arguments
las
A LAS object representing the point cloud data.
res
Grid resolution. If two non-empty voxels are contiguous, they are considered part of
the same component.
min_pts
Minimum number of points in a cluster. If a cluster contains fewer than min_pts
points, it is assigned an ID of 0, indicating that it does not belong to any group.
name
A string specifying the name of the new attribute used to store the ID of each cluster.
connectivity
integer. 6, 18 or 26 neighbors search.
Value
A LAS object with an additional attribute named as specified by name.
