FitCircleToPoints
| Header: | FIL.h |
|---|---|
| Namespace: | fil |
Approximates points with a circle using selected outliers suppression method.
Syntax
C++
C#
void fil::FitCircleToPoints ( const ftl::Array<fil::Point2D>& inPoints, fil::CircleFittingMethod::Type inFittingMethod, ftl::Optional<fil::MEstimator::Type> inOutlierSuppression, ftl::Conditional<fil::Circle2D>& outCircle )
Parameters
| Name | Type | Default | Description | |
|---|---|---|---|---|
 |
inPoints | const Array<Point2D>& | ||
|
inFittingMethod | CircleFittingMethod::Type | ||
|
inOutlierSuppression | Optional<MEstimator::Type> | NIL | |
 |
outCircle | Conditional<Circle2D>& | Fitted circle or nothing if method failed to converge |
Description
The operation computes a circle which approximates the input points best. Several methods are available, AlgebraicKasa being the fastest one. It is also the most inaccurate when the input points are sampled along small arc only.
Examples
 |
The resulting outCircle drawn with the input points, inFittingMethod = AlgebraicKasa and inOutlierSuppression = Auto.
