Approximates points with a circle using selected outliers suppression method.
| Name | Type | Description | |
|---|---|---|---|
 |
inPoints | Point2DArray | |
|
inRange | Range* | Determines which array points take part in fitting process |
|
inFittingMethod | CircleFittingMethod | |
|
inOutlierSuppression | MEstimator* | |
 |
outCircle | Circle2D? | Fitted circle or nothing if method failed to converge |
|
outInliers | Point2DArray | Points matching the computed circle |
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.
Errors
This filter can throw an exception to report error. Read how to deal with errors in Error Handling.
List of possible exceptions:
| Error type | Description |
|---|---|
| DomainError | Outlier suppression is supported only in algebraic fitting methods. |
| DomainError | Range exceeds the input point array in FitCircleToPoints. |
Complexity Level
This filter is available on Basic Complexity Level.
