Edge count
Description
This control allows you to detect all the edges (edge detection
) that are within a specific ROI.
Based on the first derivative of the pixel brightness variation function, the maximum positive peak
is identified if control is targeting a positive edge, or the maximum negative peak is identified
when targeting a negative edge. A point is considered an edge point when its brightness variation
exceeds this threshold, which is a function of the peak value found.
Selection
Positioning
Select the control and press
SET
on the corresponding icon to create the rectangular ROI in the
middle of the field range.
To modify the position of the ROI, move to the
Move ROI
icon and then press
SET
. It is now
possible to move the ROI using the
ARROW
buttons. Once you have achieved the desired
position, press the
TEACH
button to return to the Setup menu. If you wish to modify the ROI
size, select the
Resize ROI
from the Setup menu (using the
SET
