cvFitLine

Basic

Module: OpenCV

Fits a line to a 2D or 3D point set.

Name Type Description
Input value inPoints Point2DArray Input Point2D array.
Input value inDistType CvDistanceType Distance used by the M-estimator.
Input value inParam Real Numerical parameter for some types of distances. If it is 0, an optimal value is chosen.
Input value inReps Real Sufficient accuracy for the radius [distance between the coordinate origin and the line].
Input value inAeps Real Sufficient accuracy for the angle. 0.01 would be a good default value for reps and aeps.
Output value outLine Line2D
