Shape Search
The geometry correlation search for conducting search based on the
profile information of the workpiece ensures greater absorption of
dimensional variations among individual works (changes in background,
contrast, etc.) and consequently achieves stable detection.
The detection speed is approx. 20 times that of a conventional
processing system, which allows for high-speed detection even when
images are captured with high-resolution camera.
High Speed / High Precision Pattern Recoginition
Sensitive Search
This allows the recognition of very subtle differences that cannot
be detected through ordinary search processes, by dividing the
registered model image into several pieces and carefully matching
them. Thus you don't have to spend a lot of time for delicate threshold
setting.
Flexible Search
When inspecting workpieces with some variations in shape, such
variations are sometimes recognized erroneously as defects. Flexible
Search ensures accurate searches regardless of some variations in
print quality or shape, by registering several images of non-defective
products as models. It helps you decrease your inspection failure
rate by rejecting defective products only.
Different conditions for
dividing the model image can
be set.
Area / Labeling
Dynamic segmentation and high-performance
labeling
This item features a dynamic segmentation in addition to the
conventional labeling. This function ensures the accurate detection of
labels by automatically sensing any uneven color depth in the same
image and changing thresholds locally.
High Performance Edge Detection
Scan Edge Position,Scan Edge Width
Edge positions and widths can be accurately detected by dividing
the area to be inspected into several segments.Scan Edge Position
measures the points closest and farthest to the edge as well as the
inclination and surface conditions of the workpiece to be inspected.
Scan Edge Width measures the local and average widths of the
workpiece.This allows the accurate measurement of the positions of
the workpiece's peripheral parts as well as its bore diameters.Edge
detection method can be chosen from the intensity projection method
and the differentiation method.

Ordinary segmentation
Dynamic segmentation
It is also useful for measuring the
depths of grooves on metal shafts.
Registered model image
Even low-contrast images
are detected stably.
