echoSegment.TSD: Extracts a subvolume of the data enclosed in the bounding box...

In arnejohannesholmin/cpplot3d: 3D-plotting and segmentation of sonar data

Extracts a subvolume of the data enclosed in the bounding box or ellipsoid specified in the input, and calculates the total echo energy in the subvolume. Optionally the bounding object is plotted on top of an existing plot.

Description

Extracts a subvolume of the data enclosed in the bounding box or ellipsoid specified in the input, and calculates the total echo energy in the subvolume. Optionally the bounding object is plotted on top of an existing plot.

Usage

echoSegment.TSD(
  data = NULL,
  object = c("ellipsoid", "cuboid"),
  par = c(1, 1, 1),
  center = c(0, 0, 0),
  angle = 0,
  plot = TRUE,
  seg.col = "green",
  alpha = 0.2,
  subdivide = 3,
  excl.neg = TRUE,
  full.out = FALSE,
  ...
)

Arguments

data	is a list containing the acoustic data and the vessel data, as returned from read.event(var=c("vbsc","voxels","vessel")).
object	is string representing the type of object to use. Currently implemented are "ellipsoid" and "cuboid" (may be abbreviated).
par	is a vector of three elements representing the semi axis lengths for ellipsoid and the x-width, y-depth and z-height of cuboid.
center	is a vector of three elements representing the centre position of the object.
angle	is the angle of the major axis of the ellipsoid in the x-y-plane, in the case that object=="ellipsoid".
plot	is TRUE if the object should be plotted as an rgl-object.
seg.col	is the color of the object in case plot==TRUE.
alpha	is the transparacy of the object in case plot==TRUE.
subdivide	is the density of points on the plotted ellipsoid.
excl.neg	is FALSE if negative mass values are to be included in the calculation of the centers of mass of the school.
full.out	is TRUE to return voxel positions, volumes and acoustic data inside the segmente, as well as the segmentation mask.
