Lidar segmentation — wbt_lidar_segmentation • whitebox

Segments a LiDAR point cloud based on differences in the orientation of fitted planar surfaces and point proximity.

Usage

wbt_lidar_segmentation(
  input,
  output,
  radius = 2,
  num_iter = 50,
  num_samples = 10,
  threshold = 0.15,
  model_size = 15,
  max_slope = 80,
  norm_diff = 10,
  maxzdiff = 1,
  classes = FALSE,
  ground = FALSE,
  wd = NULL,
  verbose_mode = NULL,
  compress_rasters = NULL,
  command_only = FALSE
)

Arguments

input: Input LiDAR file.
output: Output LiDAR file.
radius: Search Radius.
num_iter: Number of iterations.
num_samples: Number of sample points on which to build the model.
threshold: Threshold used to determine inlier points.
model_size: Acceptable model size.
max_slope: Maximum planar slope.
norm_diff: Maximum difference in normal vectors, in degrees.
maxzdiff: Maximum difference in elevation (z units) between neighbouring points of the same segment.
classes: Segments don't cross class boundaries.
ground: Classify the largest segment as ground points?.
wd: Changes the working directory. Default: NULL will use the value in WhiteboxTools settings, see wbt_wd() for details.
verbose_mode: Sets verbose mode. If verbose mode is FALSE, tools will not print output messages. Default: NULL will use the value in WhiteboxTools settings, see wbt_verbose() for details.
compress_rasters: Sets the flag used by 'WhiteboxTools' to determine whether to use compression for output rasters. Default: NULL will use the value in WhiteboxTools settings, see wbt_compress_rasters() for details.
command_only: Return command that would be executed by system() rather than running tool. Default: FALSE.

Value

Returns the tool text outputs.
