FitLineToPoints_RANSAC (FitLineToPoints RANSAC)

Expert

Module: FoundationBasic

Approximates points with a line using a RANSAC algorithm.

Applications

Finds a well matching line, but for handling outliers requires a distance threshold that may be difficult to set.
Name Type Range Description
Input value inPoints Point2DArray
Input value inRange Range* Determines which array points take part in fitting process
Input value inMaxOutlierCount Integer* 0 - Determines how many outlier points can be present to end the search
Input value inMaxInlierDistance Real 0.0 - Distance from the output line for a point to be considered an inlier
Input value inIterationCount Integer* 1 - Number of iterations; Auto means that all point pairs will be used
Output value outLine Line2D?
