Full Motion ANPR Capture
Videofit employs the first full-motion
anpr recognition engine and offers new levels of accuracy
and functionality. For the first time it is now possible
to capture images of drivers with repeatable consistency
and without a separate video recorder. This is achieved
by new ANPR-M technology that allows a recognition and
up to 3 associated overview cameras to capture short
movies at the moment of recognition.
If occupant images are critical for your
project we would strongly recommend using more than
one camera per lane, with each camera recording an anpr-m
movie sequence to ensure success. Many projects, however,
do not warrant a large number of cameras but, nonetheless,
occupant images are still very desirable.
Using a well-positioned, wide dynamic
range colour camera, Videofit will provide good occupant
images under most lighting conditions without compromising
recognition accuracy.
Here is a typical sequence showing anpr-m
in action (right). The plate is detected in the first
frame and, with most anpr systems, only the first or
second image would be available to review. Videofit,
however, continues recording to obtain images of the
front seat occupants.
Obtaining good images of the driver and
front seat passenger is subject to many factors. The
camera needs to be well positioned with respect to the
local light sources (including the sun) and will need
a polarising filter to reduce windscreen glare. Best
results are obtained during the day, when the weather
is good and when the camera is positioned over the roadway.
If you need advice on positioning anpr cameras please
contact us.
Each camera can be set to record movies
of up to 21 frames, of which 10 may be pre-event images.
For even greater control the rate of capture can also
be reduced which is particularly useful for slow moving
traffic at site entrances and car park barriers. |
