Add a "Position" control to current inspection to identify up to two edges.
Select "Position" 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 dark-to-light brightness variations as edges. In
addition, set the maximum number of positions to be detected to '40'.
A yellow line appears inside the ROI on the edges found; edges are displayed as
yellow dots that identify the limit values for distance calculation.
Now use the sliders of the Min and Max fields to specify how far the
measurements taken on master images are allowed to deviate from the
measurement you have just set and still be considered acceptable (i.e. without
triggering a control "Fail" status).
In this second example another possible usage scenario is presented. In this particular task, it’s
needed to verify the correct placement of the beak of a bottle of water-closet detergent. As shown in
Fig. A and B, with the Position Control Tool it’s possible to achieve this task. The Fig. A shows a
correct placement, on the contrary the Fig. B shows a wrong placement.
