Click + Track
In order to track a single target, the
Track Single Target
option can be selected from
the Targets menu. This restricts the user to select one target at a time and has the benefit of
displaying the target position. As the target is tracked the Range/Bearing and X/Y Position
will be updated from each sonar frame.
The
Track Multiple Targets
option can be used to select and follow multiple targets.
Each right-click will attempt to find a target and track it separately. No position information is
displayed when tracking multiple targets. If the user changes from Multiple to Single tracking,
the target closest to the sonar will be used.
The
Reset Targets
button will clear all selected targets. This is useful when an incorrect
target has been selected or the user wants to track a new target.
Note
Noisy conditions may lead to inconsistent target recognition and tracking.
Targets that overlap with other objects or sections of visible seabed may result
in large targets that encompass more than the desired target. Ideally, a target
will have a high contrast to its surroundings.
