The readability of a vehicle
licence plate, for example, will
change according to atmospheric
conditions and dirt on the plate. An
image-processing application can
monitor the readability of the license
plate and can instruct the light
controller to automatically adjust
lighting intensity if necessary.
Three main questions
When specifying and designing
an ITS system, we would advise
planners to consider three main
questions:
• How much light is needed to
acquire images of sufficient
quality?
• Where do I need to direct the
light to be in order to enable
image capture?
• Which wavelength is most
appropriate choice?
The answers to these questions
are the starting point for any
ITS planner. n

The rapid movement of vehicles
also poses challenges in getting
sharply focused images of licence
plates. Current procedures involve
taking several sequential images
and selecting only the sharp images.
However, by using tunable lens
technology from Optotune powered
by a Gardasoft lens controller,
lens focus can be adjusted in just
milliseconds to provide real-time,
sharply focused images.

Providing Ultimate Flexibility
The ITS traffic strobes from
Gardasoft have been designed to
deliver the rapid, accurate, highintensity
LED light pulses that are
necessary for demanding traffic
applications. One of the reasons that
Gardasoft strobes are popular is that
they are able to very rapidly change
the intensity and frequency of pulses.
This enables them to reliably deliver
the correct amount of illumination
required by the vehicle position and
distance, enabling the requisite
vehicle data to be captured.
