Example
Add an "Edge count" control to current inspection to identify up to two edges.
Select "Edge Count" from the pull-down menu:
Position the control on the reference image in the work area: the
pointer changes shape as soon as it enters the work area.
Left-click once at any position to create a default rectangular
ROI.
At the same time, the control features and the result of its
application to the reference image appear in the control panel.
Set ROI size and position as required, as explained above.
The result indicated by STATUS is also highlighted by the ROI
border changing colour.
As soon as values change, result is calculated without delay.
Set up system to recognise all light-to-dark and dark-to-light
brightness variations as edges. In addition, set the maximum
number of edges to be detected to '2' (this value can be
viewed by placing the mouse pointer on the corresponding
bar). In the example figure, five edges with the specified
features have been recognized. The control will return a Fail status, identified by the red Status and
ROI border.
