details and artefacts and smoothing the image.
Range
Each grey value is replaced by the range value (maximum gray level
−
minimum gray level) of the pixels found inside the filter mask (e.g. 3x3).
Typical applications include the detection and enhancement of edges and the
improvement of local image contrasts. (starting with firmware 1.5.x.x)
Standard deviation
Each grey value is replaced by the standard deviation of the pixels found
inside the filter mask (e.g. 3x3).
Typical applications include the highlighting of surface defects or edges.
Edge detection (Sobel)
Result image contains edges detected using the Sobel-algorithm (compare
image processing literature also).
Typical applications include the detection and enhancement of edges and the
improvement of local image contrasts or the detection of surface defects.
Multiplication
The grey value of each pixel is multiplied by the choosen multiplier (2x, 4x,
8x, 16x). Values are clipped to 255.
Inversion
Inversion of image
The effect of an active filter is immediately visible in the image. The larger the filter core is selected, the
stronger the effect of the filter. The filters are used in the order listed from top to bottom.
Configuring filters:
1. Select the filters in the required order, via the pop-up menus in the column Filter.
2. Enter the size of the filter kernel in the pop-up menu in the column Property. If the setting is Off,
the respective filter is deactivated.

4.6.1.6 Calibration
The function "Calibration" transforms the image coordinates (pixel) into world coordinates (e.g.
millimeter). When activated all position and distance data is calculated in the selected unit.
