Parameters

points
Type: System.Collections.GenericIEnumerableCvPoint2D32f
Sequence or array of 2D points with floating-point 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.
