The Best Fit (BF) and Best Fit Recompensate (BFRE) constructed lines have the option of filtering the deviations of the measured data points from the best fit line computed from the measured data.
Apply Gauss Filter - If you select this check box, PC-DMIS applies a Gaussian filter which controls the smoothing by the cutoff wavelength. Generally, a longer cutoff wavelength produces smoother filtered data.
Remove Outliers - If you select this check box and you are filtering the data, it removes the outlier data prior to filtering.
For 2D lines, PC-DMIS filters the deviations in a plane parallel to the workplane.
For 3D lines, PC-DMIS filters the deviations in two planes perpendicular to each other, both planes containing the line. PC-DMIS filters these deviations in 3D.
