In this section, set the tool to judge whether a target
is high-quality-target or low-quality-target in the
master image.
The aspects of a target registered as a master
image are set as a high-quality-target. During an
operation, the sensor judges whether it is a high-
quality-target or low-quality-target by judging the
differences in the registered high-quality-target and
a target to be examined.
Up to 16 detection tools in one program and up to
1 position adjustment tool can be set. Those tools
can judge a target at the same time.

Outline tool
A detection tool to calculate the matching rate for
the target to be examined based on the outline
information of a registered high-quality-target.
Judges whether a target is a high or low-quality-
product by setting the threshold to the matching
rate.

Tool settings
Master image Outline extraction processing
Processing and judgment during an operation
Internal processing <Judge is OK>
Searches a target which has the outline of same shapes
as an outline of a high-quality-target.
Outline can be detected even if a target is rotated.
Example when the result was NG
No same shapes exist
(Detection of existence)
Different shape
(Shape detection)
Different direction
(Detection of direction)
The matching rate is indicated in 0 to 100.
100 indicates that an outline is completely matched.
The matching rate decreases in accordance with
the number of non-matched parts.
