This type is only available for Perceptron sensors.
Starting with PC-DMIS 2019 R2, PC-DMIS no longer supports the Perceptron laser sensor. While you may still be able to install PC-DMIS 2019 R2 and later, PC-DMIS displays an error if you attempt to run measurement routines that use the Perceptron scanner. For additional information, please contact Technical Support.
Median Filter type
The Median filter smooths laser stripe data by computing a new location for each pixel. For each pixel in the stripe, the median filter takes the nearest neighboring pixels, computes the median, and uses the median for the new location of the pixel.
Neighbor #: This value determines the number of total neighboring pixels that the software considers when PC-DMIS calculates a new location of any given pixel in a single stripe.
For example, if the number of neighbors is 9, then for each pixel in the stripe, the filter takes four data points to the left and four data points to the right (for a total of 9 pixels, including the current one). It then computes the median and uses it for the location of the current pixel.
Point Reduction Filter - This check box determines whether or not PC-DMIS filters points along the scan line. If marked, you can select the desired percentage of total points to filter. If cleared, PC-DMIS acquires the complete data set without any filtering.
