FitSegmentToStripe3D


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

Name Type Range Description
inSurface Surface Surface to fit segment to
inFittingField SegmentFittingField Segment fitting field
inFittingFieldAlignment CoordinateSystem2D* Adjusts the fitting field to the position of the inspected object
inScanCount Integer 3 - The number of points that will be searched to estimate the position of the segment
inSamplingStep Real* Desired distance between consecutive sampling points on the scan segments; if Nil, the bigger of surface X and Y scales is chosen
inScanWidth Integer 1 - The width of each scan field (in pixels)
inSurfaceInterpolation InterpolationMethod Interpolation method used for extraction of surface points
inStripeScanParams StripeScanParams3D Parameters controlling the stripe extraction process
inStripeSelection Selection Selection mode of stripe
inLocalBlindness LocalBlindness* Defines conditions in which weaker edges can be detected in the vicinity of stronger edges
inMaxProfileGapWidth Integer* 0 - Maximal number of consecutive not existing profile points
inMaxIncompleteness Real 0.0 - 0.999 Maximal fraction of stripe points not found
inOutlierSuppression MEstimator* Selects a method for ignoring incorrectly detected points

diagScanSegments Segment2DArray Segments along which the scans were run
diagSamplingAreas Rectangle2DArray Areas from which the input image is sampled
diagHeightProfiles ProfileArray Extracted surface height profiles
diagResponseProfiles ProfileArray Profiles of the edge (derivative) operator response
