Detect boundary line, and calculate position value at which boundary line meets start
point and end point of window (In case of horizontal boundary line, left end and right end
in inspection window).
Angle inspection
Measure angle of boundary line in inspection window.
For angle inspection, segment inspection window and detect boundary line in
segmentation region. Calculate angle of boundary line in inspection window by using
position of the detected boundary lines.
Point Num
This will be activated if both of angle inspection and SubPixel are checked.
Check at „Point Num‟ to input the number of inspection window segmentation for angle
inspection.
Color map
Select this option for binarization of color image using color information. Adjust color,
saturation, and luminance to clearly display boundary line to be detected in color map
displayed by clicking setting button.
Virtual line offset:
This function is to inspect relative position of 2 reference points.
Refer to BLU inspection.
Normal criteria (boundary line position)
Min: min position of boundary line within inspection window to judge edge position as
normal.
Current: position of detected boundary line.
Max: max position of boundary line to judge edge position as good in inspection window.
Max expansion: max range to detect position of boundary line. In general, enter width or
length of inspection window according to inspection type.
Angle Offset
Enter reference angle for good/defect judgment during angle inspection. Decimal point
can be entered.
② Inspection result in status screen
Position move inspection
Width, Height: height and width of inspection window.
- Edge
Inspect Vertical Line: detect vertical boundary line.
MV-9 User Manual

Left to Right: search boundary line from left to right.
Black to White: detect positive boundary line.
- Pixel:
Pixel express position of boundary line and normal range by the number of pixel in
the inspection window. There is min, current and max. Value in brackets next to
max value means max allowable value.
Position detected by search type will be displayed for current value.
- Micro Unit: this information is displayed when real unit information view is selected in
[Config. - Default setting - view]. Real length relevant to pixel.
[Figure 5-81 position move inspection result]
Line inspection
- Pixel: current value (11.6, 28.1) is the position of intersection point of left and right ends of
boundary line and inspection window in inspection window.
[Figure 5-82 line inspection result]
Angle inspection
- Fit Angle: angle of detected boundary line.
- Angle Offset [Ref Offset]: angle of detected boundary line, and Ref Offset means reference
Angle Offset for good/defect judgment.

Angle inspection using SubPixel
- If SubPixel is used, it segment inspection area. Position of boundary line detected in
segmented area will be displayed in the screen.
