Application
New applications with GigE Vision networking
Concrete crack propagation
One application example can be found in the field of stress
testing of building elements where there is a need to monitor
structural crack propagation as real life building elements are
disintegrated under controlled pressure. As the building ele-
ments under test have a significant size, it would require multiple
cameras set up in a network configuration.
This could be a set-up of between 15 and 20 cameras around a
full size concrete dome structure with the aim of mapping and
documenting a stress test from all angles of the dome structure
just before and during the collapse. Using a star network topol-
ogy configuration with cables up to 100 meters long, it is pos-
sible in this example to use 4 PCs each getting 12 synchronized
frames per second from multiple 1920 x 1080 pixel cameras.
High-end surveillance
Another example where JAI’s GigE Vision camera technology is
ideal in Ethernet configurations is in high-end surveillance sys-
tems e.g. airport security systems. One operator would be able
to monitor 12 XGA or 30 VGA cameras at 10 fps simultaneously
from the same network string while another security operator in
a completely different location at the airport, would be able to
monitor the same cameras at the same time, or even a completely
different set of cameras. Applying Ethernet network configuration
together with JAI’s high resolution cameras provides maximum
flexibility in any kind of high-end surveillance application.
Frame buffering
JAI’s GigE Vision cameras feature built-in frame buffers where
image frames can be stored until the application software
is ready to retrieve them. This feature is especially useful in
applications where there is a need to capture a large amount of
images from multiple cameras in a network during a very short
time frame.
An application example could be capturing images of train
wheels in motion as the trains pass by at full speed. The images
are captured almost simultaneously and stored in the camera
buffer. When the train has passed, the images are transferred
from the camera buffer to the application software at the speed
the software is ready to retrieve them. This scenario would only
require a single computer.
Heavy image processing
In cases where heavy image processing is needed, multiple
processors can be put to work using a round-robin technique.
Using JAI GigE Vision cameras in networks is opening up for a
range of new and advanced imaging applications. If you would
like to discuss these new exciting possibilities, please contact
JAI or your local JAI distribution partner.
An increasing number of JAI’s customers with knowledge of network topology are now using and
evaluating JAI’s GigE Vision cameras, in a range of new types of imaging applications. Many of
these new applications have not been possible before, at least not at an acceptable price level.
