7.4. Position

• Des

cription

This control allows you to detect the edge (edge detection

) and the position of the object

inside the relative 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 button again). It is now possible

to increase or decrease the ROI size using the ARROW buttons.
