3 Settings for 3D / 2D Parameters in
"smart-chart"
In order to optimize the 3D / 2D measurement results for a specific structure
the following parameters can be adjusted in the Standard Management
module of "smart-chart".
3.1 Settings for 3D Topography Data (Watershed
Analysis)
Segmentation parameter
... smoothes the surface topography to avoid over / under segmentation. The
true data for the 3D analysis is not affected. The parameter range is from 1.0 to
100.0. The default setting is 10, which is also used in the instrument
firmware.
If the filter offset = 1, a strong smoothing of the input data will take place. If
the filter offset = 100, little smoothing will be done.
Examples:
The left image in the figure shows the 3D data as a grey scaled image. The im-
ages next to it show different segmentation results for different segmentation
parameters. The green lines indicate the watershed segmentation results. The
images below show the smoothed topography as red line and the segmenta-
tion borders as green lines, illustrated in abstracted form.
