FitSegmentToPoints_RANSAC


Module: FoundationBasic

Approximates points with a segment using a RANSAC algorithm.

Applications

Finds a well matching segments, but for handling outliers requires a distance threshold that may be difficult to set.
Name Type Range Description
inPoints Point2DArray
inRange Range* Determines which array points take part in fitting process
inMaxOutlierCount Integer* 0 - Determines how many outlier points can be present to end the search
inMaxInlierDistance Real 0.0 - Distance from the output segment for a point to be considered an inlier
inIterationCount Integer* 1 - Number of iterations; Auto means that all point pairs will be used
outSegment Segment2D?
