3.2.2.6. Configuring and testing motion detection zone parameters of adaptive
objects detector
VideoNet system enables to configure parameters separately for each selected
in preset motion detection zone of adaptive objects detector. To set up motion
detection zones use detection setup buttons placed under demonstrational display
(see 3.2.2.1 ) and controls on the adaptive objects detector setup panel (see
picture
3.2.2-9
).

Description
This control enables to set in percentage terms alarm level of
contrast between object and background. The more contrast level,
the more contrast between object and background must be for
camera-detector to detect the object motion.
This control enables to set in conventional units from 1 to 15 object
minimum size, motion of which can be detected. Motion of all
objects with size, which is less, than specified, won’t be detected.
This control enables to set in conventional units from 1 to 15 object
maximum size, motion of which can be detected. Motion of all
objects with size, which is more, than specified, won’t be detected.
These controls enable to set maximum and minimum aspect ratio
between object width and height. If an object ratio differs from a
specified one, motion of such an object won’t be detected.
Please, be aware that configuring detection parameters is performed
experimentally. That’s why multiple repetition of steps of the algorithm, given below,
is required. For convenience it is recommended to configure
adaptive objects
detector motion detection
parameters in preset testing mode.
Attention! Adaptive objects detector working efficiency in many respects
depends on detection parameters configuring. That’s why it’s so important to
be able to configure detection zones parameters properly.
