Auto-Teach Inspection Tool
NEW

An inspection tool that “auto-teaches”; Just running
non-defective workpieces completes the application setup
Just run non-defective
The newly incorporated “Auto-Teach inspection tool” that uses the image sensor to
learn variations and individual differences that exist in the non-defective
workpieces and recognises workpieces that differ from these as defective
workpieces. These algorithms, which are unlimitedly close to the human sensation,
eliminate unstable elements to successfully guide on-site inspection. Settings are
performed just by running non-defective workpieces, and resolves the conventional
highly expertise and the complication of settings. This is an inspection tool that
makes it possible for anyone to achieve and maintain the stable inspection.

In most cases, dimension/geometric measurement requires multiple tools and
complicated calculation processing. With the CV-X100 Series, dimension/geometric
tools that resolve this complicated processing with a clicking alone has been
prepared. Because point and straight line information from other tools can also be
referenced, it is possible to construct programme settings that are simpler and

inspection tool
A stain tool is incorporated to realise the appearance inspection without eliminating the nondefective workpieces. A variet y of parameters such as size, density, shape, and count are used to
accurately nd the aw that you wish to detect.
Flaw detection for resin cap Flaw detection for nonwoven fabric cloth (ne colour)
Detects the aw on the prole of the product. The prole is automatically extracted just
by setting the inspection region to surround it. In addition to geometric shapes such
as circles and straight lines, the oval or the prole with the complex shape consisting
of the free curve is supported.
At 0.025 pixels, a search accuracy
that is equivalent to the best in the
industry is achieved along with
linearity and repeatability.
Demands to improve search
precision through target
miniaturisation and changes to
high-accuracy are supported.
Optimised for aw object
A small aw is found in the
side of the resin cap.
The stain inspection tool is available
for the stable detection of the aw
only and ignoring the inuence of the
R surface of the side.
The full colour information captured by the colour camera is
directly processed. Regardless of any colour variation
against the background, detection can be made.
The aw occurred on the corner is detected.
Even if the product prole is changed, the
reference model follows it to catch only
changed segment.
The aw occurred on the line is detected. Only the
change of aw is caught against the reference line.

Image Optimisation
Ideal imaging to ensure stable inspection
HDR
High dynamic range capture that images inspection targets as they are
“Imaging (capture)” is an extremely important process in image processing.
The CV-X100 Series is equipped with many functions to optimise inspection images
by resolving problems that may be caused by “target workpiece conditions”,
“installation environments”, and “equipment motions” in this process.
NEW
Glare removal
Captures multiple images while
automatically changing the shutter
speed and composes them at high
speed to generate images without
blown out highlights and blocked up
shadows. Clear images ideal for
processing can be captured even
when on-site capture conditions vary
or inspection targets contain uneven
glossiness or mixed intensities.
Calibration
Removes effects of changes in the capture
conditions due to installation- and
hardware-related factors such as “camera
tilting ” and “lens distor tion”. This function
offers consistent capture conditions,
including replicating the same capture
conditions for line deployment and
eliminating effects of restrictions in the
installation environment.
