R Documentation

Estimate crown volume by voxelization

Description

This function volume of a 'LAS' object by thinning to a resolution specified by 'resolution', and estimating volume using the equation

Volume_{crown} = N_{occupied voxel} * Volume_{voxel}

Usage

get_crown_volume_voxel(las, resolution = 0.1)

Arguments

`las`	'LAS' object from 'lidR' package representing a tree. Crowns must be segmented using [segment_crown()].
`resolution`	numeric - resolution of voxelization

Value

A named numeric vector with element 'crown_volume_vox' (m^3).

Examples

las = lidR::readLAS(system.file("extdata", "tree_0744.laz", package="tReeTraits"))
las = clean_las(las)
cbh = get_crown_base(las, threshold=0.25, sustain=2)
las = segment_crown(las, cbh)
get_crown_volume_voxel(las)
get_crown_volume_alpha(las)
sf::st_area(convex_hull_2D(las)) #profile area, convex hull
sf::st_area(voxel_hull_2D(las)) #profile area, voxel hull
get_lacunarity(las)
