FisFilter_FitSegmentToStripe3D

This is Filter Equivalent. This function may be present in generated code, but should not be used in hand-written code.

Header:	FIL.h
Namespace:	fis

Performs a series of 1D edge detections in 3D and finds a segment that best matches the detected points.

inOutlierSuppression	Optional<MEstimator::Type>		NIL	Selects a method for ignoring incorrectly detected points
outSegment	Conditional<Segment3D>&			Fitted segment or nothing if the fitting fails
outLeftSegment	Conditional<Segment3D>&			Fitted left segment
outRightSegment	Conditional<Segment3D>&			Fitted right segment
outStripes	Optional<Array<Conditional<SurfaceStripe1D> >&>		NIL	Found stripes
outStripePoints	Optional<Array<Point3D>&>		NIL	Extracted points of middle segment of a surface stripe
outDeviationProfile	Optional<Conditional<Profile>&>		NIL	Profile of distances between the actual segment points and the corresponding reference segment points
outAlignedFittingField	Optional<SegmentFittingField&>		NIL	Fitting field used; in the image coordinate system
diagScanSegments	Array<Segment2D>&			Segments along which the scans were run
diagSamplingAreas	Array<Rectangle2D>&			Areas from which the input image is sampled
