CvFitLine2D Method (IEnumerableCvPoint, DistanceType, Double, Double, Double)

OpenCvSharp Class Library

Fits line to 2D point set

Namespace: OpenCvSharp
Assembly: OpenCvSharp (in OpenCvSharp.dll) Version: 1.0.0.0 (1.0.0.0)

Syntax

public static CvLine2D FitLine2D(
	IEnumerable<CvPoint> points,
	DistanceType distType,
	double param,
	double reps,
	double aeps
)

Public Shared Function FitLine2D ( 
	points As IEnumerable(Of CvPoint),
	distType As DistanceType,
	param As Double,
	reps As Double,
	aeps As Double
) As CvLine2D

public:
static CvLine2D^ FitLine2D(
	IEnumerable<CvPoint>^ points, 
	DistanceType distType, 
	double param, 
	double reps, 
	double aeps
)

static member FitLine2D : 
        points : IEnumerable<CvPoint> * 
        distType : DistanceType * 
        param : float * 
        reps : float * 
        aeps : float -> CvLine2D

Parameters

points: Type: System.Collections.GenericIEnumerableCvPoint
Sequence or array of 2D points with 32-bit integer coordinates.
distType: Type: OpenCvSharpDistanceType
The distance used for fitting (see the discussion).
param: Type: SystemDouble
Numerical parameter (C) for some types of distances, if 0 then some optimal value is chosen.
reps: Type: SystemDouble
Sufficient accuracy for radius (distance between the coordinate origin and the line) and angle, respectively, 0.01 would be a good defaults for both.
aeps: Type: SystemDouble
Sufficient accuracy for radius (distance between the coordinate origin and the line) and angle, respectively, 0.01 would be a good defaults for both.

Return Value

Type: CvLine2D
The output line parameters. (vx, vy) is a normalized vector collinear to the line and (x0, y0) is some point on the line.
