Example
Add a position locator to current inspection.
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.
A yellow horizontal bar appears in the ROI with a small dot marking the position of the
identified edge. In this example, the edge was set as light-to-dark transition. If edge is not
recognized correctly, move the slider to adjust Sensitivity. Or you may switch to EXPERT
mode and change the advanced parameter "Noise Rejection".
Another example of application is presented in the figures below, Fig. A and Fig. B. In particular, the
Fig. A shows how the Position Locator is forcible to detect an horizontal translation of a coffee pod
among the scene. As shown, the locator application shifts the control tool to the right and the
inspection process is correctly achieved.
