Volume Measurement in 3D
•
Tick the check box
within the Measure line:
−
The volume parameters are calculated and displayed to the right of the image.
−
To copy / save the content displayed, click with the right mouse button into the shown tables and
decide to copy or save. The values can be imported to other programs (e.g.: MS Word or MS Excel)
via the
Paste
function.
•
Setting the
Z-level
slider enables you to change the height level of the topography. The portion of the
topography lying below the set height level is filled with "water" (blue color) and the volume
parameters are calculated online only for the projecting part of the topography.
To use the
Z-level
function, load the
Profiles
3D display mode containing the
Glowscale
or
Grey
channel color to obtain optimum display.
•
If the
Measure
function
Bearing area ration
is also activated, a red marker line shows the position
of the height level in the percentage of contact area curve.
Within the Volume measurement also the ratio of
valid
data points (means signal intensities within a
given intensity threshold) is displayed.
Parameters
The following parameters are calculated:
Z
:
height level (selectable with the
Z-Threshold
and
Fill Level
sliders). The setting of this
value influences the following parameters.
Vm (z)
:
material volume above chosen height level
Vv (z)
:
void volume below chosen height level
Smr (z)
:
material volume ratio
