Benefits of Increased Resolution
Doubling the horizontal and vertical resolutions increases to-
tal resolution by a factor of four, enabling clear images for
small or complicated workpieces.
1-million-pixel Camera with Digital Interface
The video signal noise that hurt measurement precision has
been greatly reduced to enable inspections of minute foreign
matter or damage as well as highprecision positioning.
Partial Scan Function
Partial scans can be used to reduce the image reading time,
which is often the bottleneck in measurement processing
time.
Advanced Algorithms for High-precision Measure-
ments
Positioning
ECM Searches
Edge code models are used for pattern
searches. ECM searches are not easily af-
fected by deformation and dirt, and can thus
be very effective with low-contrast workpiec-
es.
EC Positioning
Model registration is not required for EC posi-
tioning. Searching is possible with shape in-
formation, such as "circle," "rectangle," or
"intersection." This achieves higher precision in measure-
ments than conventional pattern matching methods.
Reference data: Repeatability is within 1/20 pixel (OMRON test data)
Appearance Inspections
EC Defect
Geometric information is used to measure
minute defects or lowcontrast scratches in
the measurement object at high precision.
Stable detection is possible for applications
like measuring deformation in O-rings.
EC Circle Count
Circles are searched for based on a circle of
a specified size. Stable detection is possible
without undue influence by deformation or
dirt.
EC Circle Defect
Defects in circles, such as depressions and
scorching in molded items, can be easily
measured at high precision. The defect in the circle can be ex-
tracted even with a patterned background.
Reduced Work with Simple Operations
Zoom Function for 1-million-pixel Images
Zoom in to see detail clearly for easier setting and adjustment
(display enlargement supported).
High-speed Serial USB Interface
A USB interface simplifies high-speed communications be-
tween the Vision Sensor and a computer. Communications
can be used to handle measurement data, setting data, sys-
tem data, image data, and more.
