4.10.2 Pipe Parts Creation
Figure 4-68
Pipe parts creation parameters
Pipe parts are pipe detections in a patch of 25 pings that will be joined
together as a possible part of the pipe.
Pipe segment length
This length defines how many points will be outputted to the pipe
route. Basically two points per pipe segment; the center point and a
connecting point defined by two connecting segments. When a pipe
segment is the start, the end or next to a gap of the pipe route an
additional point will be added to the route.
The ‘Pipe segment length’ has also an impact on the length of the pipe
parts.
Maximum detection distance
When the detection is further away from the last detection/prediction
than the ‘Maximum detection distance’, the detection will not be added
to the pipe part.
Increasing this value allows detections further away, from the already
tracked pipe part, to be added to the pipe part.
‘Maximum detection distance’ should not be taken literal. This value is
combined with the distance between pings and the local distance
between beams on a ping to limit adding detections which are too far
away from the tracked pipe part.
Maximum number of predictions
This value defines how many predictions are allowed to be added
sequential to a tracked pipe part.
Increasing this value allows pipe tracking to pass over more pings
which do not have detections that fit the tracked pipe part.
Quality test
The detection quality is the number of detections in the pipe part. The
more detections the better the quality of the pipe part, the more
predictions the worse the quality of the pipe part. The Quality is a
number between 0 and 1, where 0 is bad to 1 is good (only
detections).
Also the ratio predictions/detections is part of the quality figure.
Depth test
When a tracked pipe part has an average distance to the sea floor
smaller than this
‘Depth’ value it will not be used in pipe routing.
Number of detections test
When the number of detections, in a tracked pipe part, is less than this
‘Detections’ value, the pipe part will not be used for the pipe routing.
The maximum value to enter is the patch size (=25 pings).
