b.
The optical axis of the camera should face the license plate of the oncoming or de-
parting vehicle. The camera's optical axis shall be as small an angle as possible with
the axis of travel of passing vehicles.
c.
The camera should be at least one meter above the headlights of vehicles. If possible,
it should not be accessible without an assistive device.
d.
In the image, the license plate should be horizontal.
e.
Adjust the camera lens angle of view so that the characters on the license plate are at
least 25 pixels high. Consider whether you want to recognize license plates with smal-
ler character sizes. For example, the characters on Italian license plates are smaller
than those of countries geographically further north. The easiest way to check the
character size of a license plate is to display the "ANPR engine status" OSD layer in Live
View and look at the "Avg. char height:" to see the character size
.
f.
Use real, moving vehicle(s) to test the settings; it's not enough to just show a plain
license plate in front of the camera.
g.
Adjust the
camera’s direction and
angle of view to make the license plate visible for at
least one, but preferably two seconds with the right character size.

Some simple but important basic settings:
a.
Upload the ANPR Engine file, and License Key to your device
accor-
ding to the email received when you purchased the device. Check the ANPR Engine
quarterly to ensure that the device is always running with the latest version of the
engine. You will also need to update the License Key for updates after a year. You need
to see in the
menu that your License key is present („License key:
CARMEN SPI
–
xxxxxx” or „USB key
-
xxxxxxx”) and your licence corresponds to the
desired region (push the „ANPR License” button and the popup window shows the re-
gion and the validity time of the license).
b.
Check that the device has the latest firmware. You can download the latest FW from
or use AR DEvice Tool. Upload it in
.
c.
.
d.
If you haven't already done so, adjust the camera angle of view and take into conside-
ration the character sizes as well
{see point (3) in this chapter}
.
e.
With the above steps and proper camera settings, you will get license plate reading
results. These events will be listed in the Live interface below the live image.
f.
After changing any settings (eg.: the field of view, position, direction of the camera,
resolution, etc.) restart the device to reset internal statistics.
