tlsrotate3d {rTLsDeep}

Rotate TLS-derived 3D Point Clouds

Description

This function rotates TLS-derived 3D Point Clouds

Usage

tlsrotate3d(las, theta, by = "z", scale = TRUE)

Arguments

las

An object of class LAS [lidR::readLAS()].

theta

Numeric defining the angle in degrees (from 0 to 360) for rotating the 3d point cloud.

by

Character defining the rotation around x ('x'), y ('y') or z ('z') axis. Default: around z-axis.

scale

if TRUE, the xyz coordinates will be scaled to local coordinates by subtracting their values to their corresponding minimum values (e.g. x - min(x). Default is TRUE.

Value

Returns an object of class LAS containing the rotated 3d point cloud.

Examples

# Path to las file
lasfile <- system.file("extdata", "tree_c1.laz", package="rTLsDeep")

# Reading las file
las<-lidR::readLAS(lasfile)

# Visualizing las file
suppressWarnings(lidR::plot(las))

# Rotating 3d point cloud around Z-axis
lasr<-tlsrotate3d(las,theta=180, by="x", scale=TRUE)

# Visualizing rotated las file
suppressWarnings(lidR::plot(lasr))
