voxelize_points {lidR}

Voxelize a point cloud

Description

Reduce the number of points by voxelizing the point cloud. If the Intensity is part of the attributes it is preserved and aggregated as mean(Intensity). Other attributes cannot be aggregated and are lost.

Usage

voxelize_points(las, res)

Arguments

las

An object of class LAS or LAScatalog.

res

numeric. The resolution of the voxels. res = 1 for a 1x1x1 cubic voxels. Optionally res = c(1,2) for non-cubic voxels (1x1x2 cuboid voxel).

Value

If the input is a LAS object, returns a LAS object. If the input is a LAScatalog, returns a LAScatalog.

Examples

LASfile <- system.file("extdata", "Megaplot.laz", package="lidR")
las = readLAS(LASfile, select = "xyz")

las2 = voxelize_points(las, 5)
#plot(las2, voxel = TRUE)
