Tip
If you have recorded your sonar data using the wrong offsets, you can still fix the offsets
using this dialog box. Check the
Override Mounting Parameters
box to apply the correct
mounting offsets to your recording.
Details
Mounting
•
X Offset
X is defined as the Sonar Head relative to the GPS antenna across track. Port is
negative and Starboard is positive.
•
Y Offset
Y is defined as the Sonar Head relative to the GPS antenna along track. Aft is
negative and Fore is positive.
•
Z Offset
Z is defined as the Sonar Head relative to the GPS antenna’s vertical distance.
Down is negative and Up is positive.
•
Orientation
This drop-down list allows you to select a number of pre-configured Sonar Head
orientations. Observe the animation to make sure your Sonar Head is facing in the
correct direction for the selected orientation. The orientation depends on how you
are using the M3 Sonar FLS. For example, a forward-facing orientation can be
used for obstacle avoidance on a remotely operated vehicle (ROV). If you wish to
create your own orientation, select
Custom
, then enter in the precise pitch, roll, and
yaw angles of the Sonar Head position.
Tip
If images appear on the wrong side of the sonar view (for example, objects on the
right appear on the left), then select one of the “Inverted” orientations.
Rotators
Select the rotator you wish to configure from the Rotators list. You can see which
axis has been assigned to each rotator.
•
Radius
The radius offset is necessary if your Sonar Head is attached to the rotator with an
arm. The length of the arm can be entered as the radius.
