Track
In order to track objects effectively, the various settings need to be optimised.
Target Size
This is the estimated size of target that is to be tracked.
Maximum Targets
This sets an upper limit of the number of targets that will be considered for tracking. Setting
this to a large number will increase the load on the computer CPU and may cause the Gemini
software to slow down.
Min. Detection Probability
This controls the ability of the software to retain, or drop targets based upon the intensity of
their acoustic return. A low value will cause the software to try and track an identified target
even when the target is very faint.
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.
