Positioning and Mounting Targets
Target Installation
Key to the operation of the CyScan system is the correct installation of targets. Please follow
the guidelines given below when installing targets on the structure/vessel.
Once the targets are installed, their relative positions can be automatically surveyed by the
system.
Installation Tips
•
Targets should be placed in positions where the sensor can see them while the vessel is
within the expected working area. Consider vertical position as well as horizontal.
•
Flat targets should not be placed too far along the structure/vessel from the expected
working area as this can reduce the viewing angle for close operations.
•
The sensor beam should not strike a flat target at an angle of more than 45 degrees to
the target surface.
•
Cylindrical targets can be viewed from any angle equally well.
Optimum Spacing for Multiple Targets
•
Targets should be positioned with unequal spacing between them – this helps the
system to distinguish between specific targets. For example, with a typical mooring
distance of 40-80m using three targets, suitable spacing between the targets would be
10m and 20m – giving a total spread of 30m.
•
Targets should be placed no closer than 5m together. Ideally they should be placed 10m
or more apart.



Targets are asymmetrically spaced,
thus making it easier for the CyScan
system to assess which reflection
corresponds to a particular target.
û
Targets are too close together
and have even spacing. This makes it
more difficult for the CyScan system to
differentiate them.
