5.2 3D Features
5.2.13 Peak Filter
Peaks that are detected by the PeakDetector algorithm can be filtered by applying the
parameters described in this section. A filtered peak appears as all 3D data set to 0, which is
the same as if no peak occurred.
Filtering peaks might increase the robustness of the 3D application by filtering peaks that were
caused by unwanted effects, such as reflections of the laser beam. The PeakFilter parameters
can be set for each of the two peaks individually.
PeakFilter parameters (replace [i] by 0 or 1):
Peak[i]_EnPeakFilter Enable peak filtering for peak [i]. If set to False, the PeakFilter settings
are ignored.
Peak[i]_PeakFilterHeightMin
Filters all peaks (columns) where 256*LL_HEIGHT <
Peak[i]_PeakFilterHeightMin (see Fig. 5.13 and Fig. 5.19).
Peak[i]_PeakFilterHeightMax
Filters all peaks (columns) where 256*LL_HEIGHT >
Peak[i]_PeakFilterHeightMax (see Fig. 5.13 and Fig. 5.19).
Peak[i]_PeakFilterWidthMin Filters all peaks (columns) where LL_WIDTH <
Peak[i]_PeakFilterWidthMin (see Fig. 5.13 and Fig. 5.20).
Peak[i]_PeakFilterWidthMax Filters all peaks (columns) where LL_WIDTH >
Peak[i]_PeakFilterWidthMax (see Fig. 5.13 and Fig. 5.20).
An illustration of the PeakFilterHeight parameters is shown in Fig. 5.19. The red line denotes a
situation where the laser peak is filtered because the height is too big or too small. An
illustration of the PeakFilterWidth parameters is shown in Fig. 5.20. The red line denotes a
situation where the laser peak is filtered because the width is too big or too small.
