Parameters

points

Type: Emgu.CVIInputArray
Input vector of 2D or 3D points, stored in std::vector or Mat.

line

Type: Emgu.CVIOutputArray
Output line parameters. In case of 2D fitting, it should be a vector of 4 elements (like Vec4f) - (vx, vy, x0, y0), where (vx, vy) is a normalized vector collinear to the line and (x0, y0) is a point on the line. In case of 3D fitting, it should be a vector of 6 elements (like Vec6f) - (vx, vy, vz, x0, y0, z0), where (vx, vy, vz) is a normalized vector collinear to the line and (x0, y0, z0) is a point on the line.

distType

Type: Emgu.CV.CvEnumDistType
The distance used for fitting

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), 0.01 would be a good default

aeps

Type: SystemDouble
Sufficient accuracy for angle, 0.01 would be a good default
