14.2. Shield Frame
Suitable for shield components.
The component angle is the tilt of the dominant straight lines that form the
component contour, and the component center is the center of that angle's
circumscribed rectangle. The outer contour comprises mostly horizontal and
vertical straight lines, and all the resulting component contours must be
connected.
Particular parameter
Method of Auto
Binarize
The method of binarizing is specified. This parameter is effective only when the
threshold is 0.
Brightness
Distinction
It searches for the threshold which improves separation of white
and black most automatically. It is suitable when the brightness
difference of an object and background is big.
Area Size
Distinction
A threshold is determined that the area judged as white equal to
the area defined as balls. It is suitable when there is nothing to
reflect in addition to an object.

14.3. Check Upside-Down
Suitable for top/bottom judgments at rectangular components.
The component top/bottom judgment occurs by checking the
brightness variation (dispersion) at the specified judgment area.
Particular parameters
Threshold of 3-sigma
The threshold of the brightness variation for check is specified. The value
specified here is compared with the brightness variation in the check area.
Threshold of Average
Usually, “0” is specified. A superfluous judging may be prevented by setting
up values other than “0”. When a value other than “0” is set up, It becomes
an error when the following three conditions are fulfilled.
1. “Dispersion” is specified as “NG Condition”.
2. The brightness variation in the check area is over the value specified
as “Threshold of 3-sigma”.
3. The average brightness in the check area is larger than this.
Center Detection
Algorithm
The calculation method of the component center is specified.
Center of
Gravity
The center-of-gravity of the detected contour.
Apex of
Rectangle
The center of the rectangle which consists of detected lines.
Check-area Offset
Enable
When “Enable” is specified, the check area is moved according to the value
specified as “Check-area Offset”. When “Disable” is specified, the check
area is set as the center of the component.
NG Condition When “Dispersion” is specified, it becomes an error when the measured
value is larger than the value specified as “Threshold of 3-sigma”
parameter. In the case of “Non Dispersion”, it becomes the contrary.
Method of Auto
Binarize
The method of binarizing is specified. This parameter is effective only when
the threshold is 0.
Brightness
Distinction
It searches for the threshold which improves separation of
white and black most automatically. It is suitable when the
brightness difference of an object and background is big.
Area Size
Distinction
A threshold is determined that the area judged as white
equal to the area defined as balls. It is suitable when there
is nothing to reflect in addition to an object.
Check-area Size X
Check-area Size Y
The size of the check area is specified.
Check-area Offset X
Check-area Offset Y
Offset of the check area is specified.

14.4. 4 Corner Fitting
Suitable for general rectangular components, when positioning by using
straight lines near the 4 corners.
Particular parameters
Start position of edges
detection (mm)
The distance from the end of a rectangle to
the straight-line portion which accuracy is
secured is specified.

Edges detection Width
(mm)
The length of the straight line portion
which accuracy is secured is specified.
