Based on the position of the patrol vehicle when a license plate is read, the SharpZ3 system can calculate the location of the target vehicle. To improve geocoding precision, you must define the exact position of the SharpZ3 cameras on the patrol vehicle roof.
What you should know
- To configure the camera orientation, you must measure the angle of the SharpZ3 cameras. For best results, use a digital level.
- The vehicle image on the Camera position and orientation page in the Sharp Portal dynamically updates to show the approximate position of the camera.
- When this feature is enabled, the system uses similar exposures on the two ALPR cameras in the SharpZ3 camera unit. As a result, you might notice slightly reduced license plate capture and read rates.
IMPORTANT: When you enable the Position and orientation
feature, custom exposure settings on the page are ignored.
Procedure
-
Enter Position measurements in centimeters to indicate where
the front of the camera is in respect to the GNSS antenna.
IMPORTANT: Take your measurements from the GNSS antenna to the front of the camera. Do not measure from the center of the vehicle.As you enter positive or negative values, the camera moves on the vehicle image. This helps you to confirm that you have entered the correct positive or negative values.
-
Measure the camera's pan, tilt, and roll using a digital level and enter the
Orientation values.
