Parameters

points

Type: OpenCvSharpInputArray
Input vector of 2D or 3D points

line

Type: OpenCvSharpOutputArray
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: OpenCvSharpDistanceTypes
Distance used by the M-estimator

param

Type: SystemDouble
Numerical parameter ( C ) for some types of distances. If it is 0, an optimal value is chosen.

reps

Type: SystemDouble
Sufficient accuracy for the radius (distance between the coordinate origin and the line).

aeps

Type: SystemDouble
Sufficient accuracy for the angle. 0.01 would be a good default value for reps and aeps.
