Pedestrians
Examples of what the system regards as pedestrians
with clear body outlines.
Good performance requires that the system
function that detects a pedestrian must
receive the clearest possible information about
the body outline, requiring the ability to iden-
tify the head, arms, shoulders, legs, upper and
lower body plus a normal human pattern of
movement.
In order that it shall be possible to detect a
pedestrian there must be a contrast with the
background and this will be affected by such
things as clothes, the background and the
weather. With poor contrast the pedestrian
may either be detected late or not at all, which
may mean that warnings and braking are late
or omitted.
City Safety can also detect pedestrians in the
dark if they are illuminated by the car's head-
lamps.
WARNING
City Safety is supplementary driver sup-
port, but it cannot detect all pedestrians in
all situations and, for example, cannot see:
partially obscured pedestrians, people
•
in clothing that hides their body con-
tour or pedestrians shorter than 80 cm
(32 in.).
pedestrians if the background contrast
•
for the pedestrians is poor.
pedestrians who are carrying larger
•
objects.
Warnings and brake interventions could be
late or not occur at all. The driver is always
responsible that the vehicle is driven cor-
rectly and with a safety distance adapted
to the speed.
DRIVER SUPPORT
Large animals
Examples of what City Safety interprets as large ani-
mals - standing still or walking slowly and with clear
body outline.
Good performance requires that the system
function that detects a large animal (e.g. elk
and horse) must receive the clearest possible
information about the body outline, requiring
the ability to identify the animal directly from
the side in combination with what is a normal
pattern of movement for the animal.
If parts of the animal's body are not visible to
the function's camera then the system cannot
detect the animal.
City Safety can also detect large animals in the
dark if they are illuminated by the car's head-
lamps.
