Combining Machine Vision and Temperature Measurement
Similarly, it can be used for 100%
inspection of the heat-sealed cellophane
cover over the nished entrée. An added
function could be laser marking of a
bad item so it can be removed at the
inspection station.
Summary
IR machine vision and temperature
measurements can be applied to an
innite number of automated processes.
In many cases, they provide images
and information that are not available
with visible light cameras, and they
also complement white light images
where the latter are required. IR cameras
like the FLIR A325 provide a stream of
digitized IR images at fast frame rates for
relatively high-speed processes, which
can be transmitted over GigE networks to
remote locations. Compliance with GigE
Vision and GenICam standards means
that such cameras can be integrated
with a wide variety of similarly compliant
equipment and supported by a broad
range of third party software. Trigger and
synchronization capabilities allow them
to control, or be controlled by, a host of
other types of equipment. The availability
of wireless and beroptic line adapters
allow these cameras to be used almost
anywhere, including over long distances.

undercooked chicken tenders and stop the line
so bad parts can be removed.
