FitLineToPoints3D_M
Header: | FIL.h |
---|---|
Namespace: | fil |
Module: | Vision3DStandard |
Approximates points in 3D with a line using selected M-estimator for outlier suppression.
Applications: Finding a locally optimal line in 3D. Good enough when the number of outliers is small.
Syntax
C++
C#
void fil::FitLineToPoints3D_M ( const ftl::Array<fil::Point3D>& inPoints, fil::MEstimator::Type inOutlierSuppression, float inClippingFactor, int inIterationCount, ftl::Optional<const fil::Line3D&> inInitialLine, fil::Line3D& outLine, ftl::Optional<ftl::Array<fil::Point3D>&> outInliers = ftl::NIL )
