Commissioning
For the majority of installations (camera on a pole at the side of road or mounted on a
gantry) the following parameters need to be entered:
FOVC X (m) : Skew value, lateral distance from camera to the centre of the capture zone
(Note that for a gantry mounted camera this will be zero)
FOVC Y (m) : Distance from camera to the centre of the capture zone measured along the
road (This is the Distance D from section 0)
Camera Z/Height (m) : Mounting height of camera
Camera Roll Angle (deg) : Roll angle of the camera, this can be taken directly from the entry
below labelled Measured Roll (deg) which is produced by the cameras inbuilt accelerometer

The values entered do not need to be precise however it is important to ensure that the sign
of the skew value (FOVCX) is correct for the installation. Refer to Figure 32 & Figure 33 which
show these dimensions for two typical install cases, one with positive and one with negative
skew.
The remaining settings allow additional adjustments to cover situations such as where the
camera is mounted away from the edge of the road on a cantilever pole or where the road
surface is raised from the co-ordinate origin point. For a detailed description of all settings
on this page refer to the Sicore II Operating Instructions Handbook (Ref para. 1.3).
