You can use the Filters tab for the Adaptive Free Form Plane Scan strategy to set up filters.
Outlier
PC-DMIS first fits a plane to the data and then determines which points are outliers based on the standard deviation multiple. It then does the following:
Recalculates the best fit plane with those outliers removed.
Checks for outliers again.
Recalculates the best fit plane.
Continues repeating this process until no more outliers exist or until PC-DMIS cannot compute the plane. (PC-DMIS cannot compute the plane if there are fewer than three data points.)
Filter
This value indicates the filter type for the scan. Some filtering options are specific to certain strategies. Select the filter type:
None - Does not apply any filter type to the scan data set.
Gaussian - Applies a Gaussian filter to the scan data set, which smooths the data.
Wave Length (mm)
Oscillations in data smaller than the value you select in the list are smoothed when applying the linear Gaussian filter. This applies to lines and planes.
You can also type a wavelength value in the box. The value is in millimeters.
This option is hidden if you select None in the Filter list.
