Find by This parameter can be used to specify which of the detected edges
will be used on the search line.
Best Score
If several edge transitions are detected on
the search line, the transition with the great-
est contrast is selected.
First Score
If several edge transitions are detected on the
search line, the first transition in the search
direction is selected.
Last Score
If several edge transitions are detected on the
search line, the last transition in the search
direction is selected.
Edge Width
(px)
The setting Edge Width controls the sensitivity of brightness changes.
Note:
• An Edge Width of 3 pixels represents the highest sensitivity in
contrast in the image.
• An Edge Width of 9 pixels smoothes the gray profile to ignore the
noise.
Threshold
Gradient Pos
(GrM)
Threshold Gradient Pos defines the threshold of the positive gradient.
Note: The gradient represents the change of brightness from pixel
to the next. The higher the contrast of an edge the higher the gradi-
ent.
Threshold
Gradient Neg
(GrM)
Threshold Gradient Neg defines the threshold of the negative gradient.
Note: The gradient represents the change of brightness from pixel
to the next. The higher the contrast of an edge the higher the gradi-
ent.
Edge Point The coordinates of the detected edge transition are displayed under
“Edge Point”:
X (px)
Coordinate of the sensor image coordinate system
(see section 18.3)
Y (px)
Orientation
Default The edge transition search direction corresponds
to the direction in which the search ray has been
drawn.
Swap The edge transition search direction is the opposite
of the direction in which the search ray has been
drawn.
