Table 14 - Geometry Acronyms - Siemens Sicore II Installation And Commissioning Manual

Installation
In summary for installation and alignment the critical values required to be determined are:
·
Height (H) – Height of camera above road surface
·
Distance D (D) – Distance along the side of the road from the camera to the centre
of the capture zone
·
Skew (S) – Distance from the camera at the side of the road measured to the
centre of the capture zone
·
Parameter Description
W Width of the street or lane to be
captured (at road surface)
W1 Width of the street or lane to be
captured (at plate height)
H Mounting height of Sicore above
road surface
D Distance from Sicore to the
horizontal centre line within the
image area
V Depth of View
V1 Distance to start of Field of View
from Camera
b
Camera Angle for horizontal
F focal length
DCN Distance Camera to Number plate
(calculated assuming a plate
50cm above the ground)
DCS Distance Camera to Street
S Horizontal Shift
