Getting Started
What happens if there is a power failure?
Does it retain the settings?
Yes. The settings are saved on an internal
hard-drive. They may be easily backed up via LAN
access as well.
What are some successful applications
realized with the Eyebot system?
Some examples are on www.Sightech.com. In short,
if you can see (image) the defect through a video
camera, then Eyebot should be able to see the defect.
Please consult Sightech with your specific needs.
What is the principle of operation of the
learning algorithm (self-teaching method through
neuronal network classification?)
Eyebot learns up to 13 million features per
second. The basic principle is that Eyebot learns
small features in relationship with other features.
During the learning process, Eyebot learns all the
features it sees. In inspection mode during the RUN
process, Eyebot complains when it sees features or
characteristics that it has never seen before.
What is the maximum pixel memory size that
can be stored into memory?
Eyebot does not store pixels – it learns
to inspect by understanding features instead.
What is the tolerance for a moving object?
What is the speed variation?
Eyebot can learn moving objects at a pace of over
1,400 per minute. It helps to train Eyebot at a
similar speed that it will inspect the object. It
doesn't have to be exactly at the speed, but the more
similar, the better. The faster the shutter speed of
the camera, the faster objects can move.
What is the best way to demonstrate the
features of the Eyebot? Any
recommendation?
Look on our web page under Applications, Eyebot Application Notes,
and Eyebot
Documentation to get an idea of some of the
problems we solve and demo. Eyebot has reasonable
default settings to begin with. Also, under Eyebot you will find
some more info. Do a demo that shows off the
self-learning ability of Eyebot. A bottle demo works
well, or have it learn and inspect raisin boxes. We
learn some good bottles/boxes, then put it in the
inspect mode, and it will see defects on the
bottle/boxes. It will take just a few minutes of
learning.
When will Eyebot make the
decision?
Eyebot makes up to (Ithink something is missing
here?) decisions every second. In other words, it can
make a decision on every video frame. On the other
hand, it can carry forward a moving average of n
video frames and bass its frame-to-frame decision on
this moving average. This speed can be selected by
the user as a choice between Strobe, Instant, Fast,
Medium, and Slow in Decision àSpeed.
If there is no strobe (trigger input), how
does the Eyebot learn as the shampoo bottle passes by
the camera?
If there is no strobe, then Eyebot will learn
EVERYTHING on the screen, including your hand (if you
stick it in the screen), the background, and
everything in the viewing area.
It takes about 1-3 minutes to learn the shampoo
bottles, assuming low UVT (see manual) and decent
lighting (we use $19 halogen lamps).
Eyebot can spot very small defects.
What is the minimum distance between two
consecutive objects?
Depending on mode, none. We can learn a continuous
stream (such as fruits and vegetables).
Is Eyebot suitable for mark inspection?
Say inspect marks on IC?
As you probably know, Eyebot does not do OCR. It
does not do Bar Code reading either.
The general rule of thumb with Eyebot is: if you
can see the defect on the screen (through the eyes of
the camera), then Eyebot should be able to see it
too. If the difference between a good mark and a bad
mark is really obvious, then Eyebot should definitely
be able to do it. If Eyebot is not able to see the
gross defect, then you should probably troubleshoot
another part of your setup.
