Parameters

Name	Type	Range	Default	Description
inSurface	const Surface&			Input surface
inScanPath	const Path&			Path along which the scan is performed
inScanPathAlignment	Optional<const CoordinateSystem2D&>		NIL	Adjusts the scan path to the position of the inspected object
inSamplingStep	Optional<float>	0.0 -	NIL	Distance between consecutive sampling points on the scan path; if Nil, the bigger of surface X and Y scales is chosen
inScanWidth	int	1 -	5	Width of the scan field in pixels
inSurfaceInterpolation	InterpolationMethod::Type		Bilinear	Interpolation method used for extraction of surface points
inStripeScanParams	const StripeScanParams3D&		StripeScanParams3D ( ProfileInterpolation: Quadratic4 SmoothingStdDev: 0.6f MinMagnitude: 5.0f MaxInnerEdgeMagnitude: Nil StripePolarity: Low MinStripeWidth: 0.0f MaxStripeWidth: Nil )	Parameters controlling the surface stripe extraction process
inMinGapWidth	float	0.0 -	0.0f	Minimal distance between consecutive surface stripes
inMaxGapWidth	Optional<float>	0.0 -	NIL	Maximal distance between consecutive surface stripes
inLocalBlindness	Optional<const LocalBlindness&>		NIL	Defines conditions in which weaker edges can be detected in the vicinity of stronger edges
inMaxProfileGapWidth	Optional<int>	0 -	1	Maximal number of consecutive not existing profile points
outStripes	Array<SurfaceStripe1D>&			Found surface stripes
outAlignedScanPath	Optional<Path&>		NIL	Path along which the scan is performed; in the image coordinate system
outHeightProfile	Optional<Profile&>		NIL	Extracted surface height profile
outResponseProfile	Optional<Profile&>		NIL	Profile of the edge (derivative) operator response
diagSamplingPoints	Array<Path>&			Array of paths each one containing the sampling points that contributed to a single value of the extracted profile; in the image coordinate system
diagSamplingStep	float&			Used distance between consecutive sampling points on the scan path

Optional Outputs

The computation of following outputs can be switched off by passing value atl::NIL to these parameters: outAlignedScanPath, outHeightProfile, outResponseProfile.
