To configure preset for adaptive objects detector:
1. Select camera-detector on the
Detection
panel.
2. Select necessary preset from the list of presets on the adaptive objects detector
setup panel (see p
icture 3.2.2-9
).
At first it is recommended to set detection parameters so that the system will
detect all changes in the scope of camera-detector. To do that, it is necessary
to set all controls to extreme positions (
steps 3-5
).
3. Set slider of contrast to maximum. In that case the system won’t detect slightest
changes in detection zones, icluding different noises.
4. Set sliders of max and min object size to maximum and minimum
correspondingly.
5. Set sliders of max and min object aspect ratio to maximum and minimum
correspondingly.
6. Click
Test
button near the list of presets. System learning, which is necessary
for detector work, starts. It takes 8 seconds. Then objects motion detecting in
configured detection zones starts. For convenience of setup the system will
display red frames on the
demonstrational display
, indicating object moving.
Now it is necessary gradually to change detection parameters, successively
cutting those changes, which will be unessential in each of detection zones
(
steps 7-9
).
7. If you want the system, in case of minimal difference between moving object
and background, to detect motion, then it is necessary to reduce contrast. For
example, if you need to detect motion of a grey object on a grey asphalt
pavement at dusk. To do that, alternating clicking and releasing
Test
button,
move the slider to the left until the system starts to detect motion of necessary
objects.
8. Alternating clicking and releasing
Test
button, start moving sliders of max and
min object size until you get needed intended target object (that object, motion
of which you want to detect). For convenience of setup click
button on
the demonstrational display. The system will display object size in percentage
of demonstrational display (see
3.2.2.5
section).
9. Alternating clicking and releasing
Test
button, move sliders of max and min
object aspect ratio until you get needed aspect ratio. For convenience of
setup click
button on the demonstrational display. As well as at the
previous step, during sliders moving sizes of rectangles will change, as it is
shown in the picture
3.2.2-5
(see
3.2.2.5
section).
10.Click
Test
button to test detection parameters, you have configured. If testing
shows that the system detects motion not of all objects or on the contrary of
those objects, motion of which shouldn’t be detected by the system, go through
the
steps 7-9
once more.
11.If the system detects motion correctly, release
Test
button to complete setup.
