Picture 3.2.2-7
Maximum object aspect
ratio is 4/7. Detected object aspect ratio is
3/8. Motion of such an object won’t be
detected by camera-detector
Picture 3.2.2-8
Maximum object aspect
ratio is 1/2. Detected object aspect ratio is
3/8. Motion of such an object will be
detected by camera-detector
Picture 3.2.2-6
Detected object
area is 24. Detected object aspect
ratio is 3/8.
In the
picture 3.2.2-6
detected object aspect ratio
3/8
is shown. Detected object area is
24
.
For example, specified minimum and maximum
object sizes are
12
and
32
correspondingly, and
minimum and maximum aspect ratios are
2/1
and
4/7
correspondingly (see
picture 3.2.2-7
). Motion
of such an object in detection zone, shown in the
scheme, won’t be detected by camera-detector,
because detected object size (that is its area)
corresponds to specified detection zone
parameters, and its aspect ratio – doesn’t
correspond.
Or for example, specified minimum and maximum
object sizes are
12
and
32
correspondingly, and
minimum and maximum aspect ratios are
2/1
и
1/2
(see
picture 3.2.2-8
). Motion of such an object
in detection zone, shown in the scheme, will be detected by camera-detector,
because both detected object size (that is its area) and its aspect ratio correspond
to specified detection zone parameters.
