Parameters

Name Type Range Default Description
inImageGridsSystem.Collections.Generic.List<System.Collections.Generic.List<Avl.AnnotatedPoint2D>>For each view, the annotated calibration grid.
inGridSpacingfloat<0.000001f, INF>Real-world distance between adjacent grid points.
inImageWidthint<1, INF>Image width, used for initial estimation of principal point.
inImageHeightint<1, INF>Image height, used for initial estimation of principal point.
inDistortionTypeAvl.LensDistortionModelTypePolynomialWithThinPrismLens distortion model. Default value: PolynomialWithThinPrism.
inImagePointsStandardDeviationfloat<0.0f, INF>0.1fAssumed uncertainty of inImagePoints. Used for robust optimization and outCameraModelStdDev estimation. Default value: 0.1f.
outCameraModelAvl.TelecentricCameraModel
outCameraModelStdDevAtl.Optional<Avl.TelecentricCameraModel>Standard deviations of all model parameters, assuming that inImagePoints positions are disturbed with gaussian noise with standard deviation equal to inImagePointsStandardDeviation.
outRmsErrorAtl.Optional<float>Final reprojection RMS error, in pixels.
outMaxReprojectionErrorsAtl.Optional<System.Collections.Generic.List<float>>For each view: the maximum reprojection error among all points.
outReprojectionErrorSegmentsAtl.Optional<System.Collections.Generic.List<System.Collections.Generic.List<Avl.Segment2D>>>For each view: array of segments connecting input image points to grid reprojections.
