public static void DetectCalibrationGrid_CircleBoard ( FilNet.Image inImage, FilNet.Size inBoardSize, float inWorldCircleSpacing, bool inFastApproximate, INullable<List<FilNet.Point2D>> outImagePoints, INullable<List<FilNet.Point2D>> outWorldPlanePoints )
Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
![]() | inImage | FilNet.Image | Input image. | ||
![]() | inBoardSize | FilNet.Size | Number of circles in X and Y dimensions. | ||
![]() | inWorldCircleSpacing | float | <0.0f, INF> | 1.0f | Real-world distance between adjacent circles centers. Default value: 1.0f. |
