QUEST Character Recognition
F160 uses OMRON's character recognition system - QUEST.
Features
• The user does not have to register characters.
• High discrimination level of similar characters.
• Adapts to fluctuations in shape and size.
"Variable Box" Measurement for Defect In-
spection
The measurement area can be set to change automatically
when performing inspections for objects with varying sizes,
such as electronic chip components. This feature ensures
that the optimum measurement areas are always used for in-
spection.
Setting screen Measurement screen
Set frames for adjusting The inspection region automatically
the region size adapts to the object size.
Flexible Search
This method performs a matching using more than one refer-
ence image and so F160 can perform inspection for objects
with varying shapes. This feature helps to reduce incorrect
evaluations.
Matching can be performed for products with varying shapes
by using more than one reference image.

Features
Use for any type of character
Rotation search
This function rotates the image while searching. Processing
speed is 10 times higher than previous models. Angle interpo-
lation enables high-precision angle detection.
Example: Searching in a rotation range of 360˚ with a skipping angle of 5˚.
Classification
A search is performed using multiple stored models, and the
best-matching model number is output. The flexible search
function can also be used for work shapes.
Can handle variations in shape.
Model1
Edge width
The positions of both edges of an ob-
ject are detected with high accuracy,
and from this the width of the object
is calculated. It is not necessary to
set expressions for calculating the
width.
Position displacement
compensation
F160 permits compensation using only
the outline of the object, 2-stage posi-
tion compensation, and setting priori-
ties for the compensation direction.
Labeling
The number of labels (i.e., objects) inside the measurement
area is counted. After they have been sorted according to
area or center of gravity, the measurement data for specified
labels is output.
Counting gears Inspecting the position and
number of buttons
Expressions
Evaluation and data output based
on a maximum of 32 expressions is
possible. Up to 32 variables (repre-
senting other expressions) can be
used, enabling more complex cal-
culations.
