Character / Code Recognition
Read Bar Codes / 2D Codes
It allows the detection of the types of products before inspections as well as the collection and accumulation of information on
inspections.
Switching among different inspection items according to the types of products
Different sets of inspection items can be automatically set for different types of
products detected through code reading processes.
The item, that covers all processes from product type detection to inspections
without involving the host, can save time for interconnection and programming.
Reading different codes at a time
Two or more different codes in the
same field of vision can be read by
utilizing a high resolution camera.This
function contributes to the reduction of
inspection tact time.
Coping with geometric computation
Circle/Line Regression
With this item, you can cope with geometric computation in addition to functional
computation.It allows you to relate coordinates very easily while looking at images.
Character Inspection / Date Verification
This item allows easy inspections of characters by registering specific
characters in the model dictionary and specifying areas to be inspected.
Calendar function
Character strings to be inspected are automatically updated by specifying
duration of use.It can allows the inspections of encrypted dates (such as "X"
representing 10).
Compatible with various
date formats
You can obtain
the center or
radius of a circle
from an arbitrary
number of points
on its perimeter.
You can obtain a straight
line, the intersection of two
straight lines and its angle,
or the distance between
a straight line and a point
from an arbitrarily selected
number of points.
Items supporting measurement
OCR mode: Reading printed characters and outputting them to an external device.
OCV mode: Judging matching with registered models
OCR + Count: Characters counted simultaneously
2D codes
Collecting and accumulating information on inspections in real time
You can collect the serial numbers of components and measuring
results in real time while they are being inspected.The causes of
defects can be tracked down immediately by consolidating such
serial numbers and measuring results at the host.

When trapezoidal
distortions are caused by
perspective differences,
significant calibration
errors are observed.
High precision
calibrations are possible
for trapezoidal distortions
by using parameters
considering perspective
transformation.
