This is a pipe detection confidence level as a numerical value
correspending with a procentual discard level; 1 means 68% of the
beams in the pipe window are discarded as noise, 2 means 95%.
4.10.2.5 Filter brightness
When checked the multibeam data with poor brightness will be ignored
for the pipe detection.
4.10.2.6 Filter colinearity
When checked the multibeam data with poor colinearity will be ignored
for the pipe detection.
4.10.3 Pipe Parts Creation
Figure 4-76
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.
4.10.3.1 Pipe segment length
The pipe segment length defines how many points will be outputted to
the pipe route. For each pipe segment one output point. E.g. when the
pipe segment length is set to 5meter, each 5 meter a point is output to
the pipe route.
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.
4.10.3.2 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.
4.10.3.3 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.
