FitLineToPoints3D_LTE


Header: AVL.h
Namespace: avl
Module: Vision3DStandard

Approximates points in 3D with a line using Least Trimmed Error algorithm.

Syntax

C++
C#
 
void avl::FitLineToPoints3D_LTE
(
	const atl::Array<avl::Point3D>& inPoints,
	int inSeedSubsetSize,
	atl::Optional<int> inEvalSubsetSize,
	avl::Line3D& outLine,
	atl::Optional<atl::Array<avl::Point3D>&> outLTInliers = atl::NIL,
	atl::Optional<float&> outLTError = atl::NIL,
	int& diagIterationCount = atl::Dummy<int>()
)

Parameters

Name Type Range Default Description
Input value inPoints const Array<Point3D>&
Input value inSeedSubsetSize int 2 - 10 3 Number of points in one combination for getting a sample line
Input value inEvalSubsetSize Optional<int> 3 - NIL Number of closest points used for evaluation of a sample line, or Auto if seed points are to be used
Output value outLine Line3D& Fitted line
Output value outLTInliers Optional<Array<Point3D>&> NIL Inlying points of the best LTE line
Output value outLTError Optional<float&> NIL The Least Trimmed Error
Diagnostic input diagIterationCount int& Number of combinations considered

Optional Outputs

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