Gemini Software Operation
Active Range Window and Active Bearing Window
These settings set up a mask around a tracked target. As long as the target moves within
the mask from one instance to the next the target will remain tracked. If the target moves
too quickly tracking will cease.
Sensitivity
Increasing the sensitivity will allow the tracking to detect more potential objects, but can result
in a greater number of false positives.
The Reset to Defaults button will reset the above settings back to default values. It will
also automatically stop any active tracking.
To track a target, click on the Enable Target Detection button and setup the settings
to suit the current environment.
Once enabled, potential
targets will be highlighted in
the appropriate colour, green
in this instance.
To track one or more targets,
place the mouse cursor over
it and right click on it. A small
cross will appear in each
target selected.
To begin tracking either:
click the Enable Active
Tracking button; or double
right click the last target. The
highlight boxes will change
colour and the other potential
targets will no longer be
highlighted.
The Tracked Targets
information will now update
with details of the primary
target to be tracked. The
primary target is denoted by a
small cross within the highlight
box.
To change the primary target,
right click another highlighted
target. The cross will then
move to the new primary
target.
The Reset Targets button will stop any tracking that is currently taking place.
