Stabilizing the Judgment Process
Stabilizing the position adjustment
This section explains how to adjust when the
position adjustment is not stable.
“Position Adjustment tool” (Page 4-51)
Basic adjustments
Set the position adjustment window as large as possible
by selecting a part that contains a unique shape.
If there are many variation of a target shapes
that a position adjustment window has been set,
set the threshold which has lower matching rate.
: Good example
Position adjustment window
Since the convex part assigned in the position
adjustment window does not exist in any other
part of the target, the position adjustment can
be performed correctly without being recognition
error.

: Bad example
Position adjustment window
Example 1
Example 2
The position adjustment cannot function
correctly in the following examples.
Example 1: The straight line that the position
adjustment window is set cannot be
identied uniquely because there
are many similar straight lines exist
in other parts of the target.
Example 2:
The angle section that the position
adjustment window is set cannot be
identied
uniquely
because there
are many similar angle sections exist
in other parts of the target.
If the target tilts and the position
adjustment becomes unstable
Search region
Rotation range
Rotation Range
Broaden the rotation range if the tilt of the target
exceeds the rotation range (default value: ± 20°).
“Rotation Range” (Page 4-57)
To stabilize the position adjustment, the tool
window will search with the range ± few
degrees wider than the setting value of rotation
range. (The tool window will search ± few
degrees even if the rotation range is set to 0°.)
Set the Margin to [OFF] when you would like
to detect the target in accordance with the set
rotation angle of the target.
“Margin” (Page 4-57)
Search Region
Broaden the search region if the variation in the
position determining of the target exceeds the
region to be searched.
“Setting a search region” (Page 4-55)
If the position adjustment becomes
unstable due to the effect of the
unwanted outlines
The outline disabling function can disable
unwanted outlines.
“Settings for disabling outlines” (Page 4-55)
Set the extraction sensitivity to [Low].
