Warning: Changing the Scene Reference Point will disable the DP Feed. This is
done because changing the reference point can dramatically alter the output
from the DP Feed. The DP Feed must be re-enabled by following the below
procedure.
Adjusting the Scene Reference Point
Scene Reference Point
This is the point within the scene that SceneScan will report its position relative to. By
default SceneScan will select the centre of the tracked scene as its Scene Reference
Point, with a heading of 0°.
This behaviour should be sufficient for most users. However, users are also able to edit
the Scene Reference Point, altering both its position and heading. This might be done
to align to the heading of a tracked vessel, or to position oneself against the edge of a
platform or quayside.
To Edit the Scene Reference Point:
1. Ensure that the Dashboard is In Command (see In Command Mode on page 33)
and is Tracking. It does not matter whether DP Feed is enabled or not.
2. Press the Tracking button to bring up the Tracking Menu.
3. Press the Edit Tracking button.
4. Now the Scene Reference Point can be edited as follows:
1. Left Click on the scene with the mouse to move the reference point to the
clicked location. If Snap To Scene is selected then clicking the scene will
move the reference point to the closest point of Scene Data. This is useful
when trying to align with the edge of a structure.
2. Right Click + Drag on the scene with the mouse to rotate the reference
point, altering its heading.
3. Select Rotate to change the mouse behaviour such that Left Click + Drag
now rotates the reference point. This is useful for touch screens.
4. Use the Align Heading control on the Tracking Menu to precisely control the
heading.
5. Once you are done, press Apply on the Apply/Cancel pop-up.
Note that pressing the Reset button at any point during the edit will undo your
changes without Cancelling your Edit. In addition, the zoom controls can still be
used to alter the zoom level of the central BEV while selecting the reference point.
