voxel_array_from_point_cloud: Convert a point cloud to a voxel array

In niknap/slidaRtools: Tools for lidar simulation and lidar processing

Convert a point cloud to a voxel array

Description

Function that takes a point cloud in XYZ-data.frame format and returns a 3D array of custom horizontal and vertical voxel resolution.

Usage

voxel_array_from_point_cloud(
  XYZ.df,
  global.h.max = NA,
  res.xy = 5,
  res.z = 5,
  value.var = "Z",
  func = "count"
)

Arguments

XYZ.df	Lidar point cloud in XYZ-data.frame format
global.h.max	Maximal Z of the array (if not set, the maximal Z of the point cloud is taken)
res.xy	Horizontal sidelength of the voxels
res.z	Vertical sidelength of the voxels
value.var	Variable (data.frame column) from which to derive the voxel values
fun	Aggregation function ("bool", "count", "min", "mean", "max", "sum")

Value

3D array
