Pedestrians
Optimal example of what the system considers to be a
pedestrian: clear body contours
To help function optimally, City Safety's function
for pedestrian detection needs clear information
about the person's head, arms, shoulders, legs,
the upper and lower parts of the body and a per-
son's normal pattern of movement.
In order to detect a pedestrian, there must be a
contrast to the background. If there is little con-
trast, the person may be detected late or not at
all, which may result in a late or no reaction from
the system.
•
If major parts of the pedestrian's body are
not visible to the camera, he/she may not be
detected.
•
In order to detect a pedestrian, the system
must have a full view of the person's entire
body and the person must be at least 32 in.
(80 cm) tall.
•
City Safety can also help detect pedestrians
in dark conditions if they are in the path of
the vehicle's headlights.
WARNING
City Safety is designed to be a supplementary
driving aid.
It cannot detect pedestrians:
•
who are partially obscured, wearing cloth-
ing that prevents a clear view of the per-
son's body contours or who are not at
least 32 in. (80 cm) tall.
•
who have limited contrast to their immedi-
ate background. A warning or braking
may be delayed or not come at all.
•
carrying a large object.
The driver is always responsible for operating
the vehicle in a safe manner.
Large animals
Examples of what City Safety considers to be large ani-
mals: stationary or moving slowly with clear body con-
tours
To function optimally, the system feature for
detecting large animals (moose, horses, etc.)
must receive as clear information about body
contours as possible. This entails being able to
detect the animal straight from the side and
assumes that the animal has a normal pattern of
movement.
If parts of the animal's body are hidden from the
camera, the system cannot detect this animal.
City Safety can also help detect large animals in
dark conditions if they are in the path of the vehi-
cle's headlights.
