FIS.CalibrateCamera_Pinhole Method

Finds the camera intrinsic parameters from calibration grids. Uses pinhole camera model (perspective camera).

Namespace:FilNet
Assembly:FIL.NET.dll

(
	IList<IList<FilNet.AnnotatedPoint2D>> inImageGrids,
	int inImageWidth,

Parameters

Name Type Range Default Description
inImageGridsSystem.Collections.Generic.IList<System.Collections.Generic.IList<FilNet.AnnotatedPoint2D>>For each view, the annotated calibration grid.
inImageWidthint<1, INF>Image width, used for initial estimation of principal point.
inImageHeightint<1, INF>Image height, used for initial estimation of principal point.
inDistortionTypeFilNet.LensDistortionModelTypePolynomialLens distortion model. Default value: Polynomial.
inImagePointsStandardDeviationfloat<0.0f, INF>0.1fAssumed uncertainty of inImagePoints. Used for robust optimization and outCameraModelStdDev estimation. Default value: 0.1f.
inFocalLengthfloat?Specify a fixed focal length (do not estimate), in pixels. In order to calculate the inFocalLength from camera parameters one needs to divide the lens focal length [mm] by sensor pitch [mm/pix]. Default value: ftl::NIL.
outCameraModelFilNet.PinholeCameraModel
outCameraModelStdDevFilNet.NullableRef<FilNet.PinholeCameraModel>Standard deviations of all model parameters, assuming that inImagePoints positions have a standard deviation equal to inImagePointsStandardDeviation. Can be null to skip this parameter calculation.
outRmsErrorFilNet.NullableValue<float>Final reprojection RMS error, in pixels. Can be null to skip this parameter calculation.
outMaxReprojectionErrorsFilNet.NullableRef<System.Collections.Generic.List<float>>For each view: the maximum reprojection error among all points. Can be null to skip this parameter calculation.
outReprojectionErrorSegmentsFilNet.NullableRef<System.Collections.Generic.List<System.Collections.Generic.List<FilNet.Segment2D>>>For each view: array of segments connecting input image points to grid reprojections. Can be null to skip this parameter calculation.
