FIS.CalibrateCamera_LineScan Method

Finds the line scan camera intrinsic parameters from calibration grid.

Namespace:FilNet
Assembly:FIL.NET.dll

Syntax

public static void CalibrateCamera_LineScan
(
	IList<FilNet.AnnotatedPoint2D> inImageGrid,
	float inGridSpacing,
	int inImageWidth,
	FilNet.LensDistortionModelType inDistortionType,
	float inImagePointsStandardDeviation,
	float? inFocalLength,
	FilNet.LineScanCameraModel outCameraModel,
	out float outApproxScaleRatio,
	out float outRmsError,
	out float outMaxReprojectionError,
	IList<FilNet.Segment2D> outReprojectionErrorSegments
)

Parameters

Name Type Range Default Description
inImageGridSystem.Collections.Generic.IList<FilNet.AnnotatedPoint2D>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.
inDistortionTypeFilNet.LensDistortionModelTypePolynomialLens distortion model. Default value: Polynomial.
inImagePointsStandardDeviationfloat<0.0f, INF>0.1fAssumed uncertainty of inImagePoints. Used for robust optimization. Default value: 0.1f.
inFocalLengthfloat?Specify a fixed focal length, 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.LineScanCameraModel
outApproxScaleRatiofloatApproximate scale ratio between Y and X. Useful for camera/encoder trigger rate configuration. When greater than 1, the image is stretched in Y dimension, when less than 1 it is compressed.
outRmsErrorfloatFinal reprojection RMS error, in pixels.
outMaxReprojectionErrorfloatMaximum reprojection error among all points.
outReprojectionErrorSegmentsSystem.Collections.Generic.IList<FilNet.Segment2D>Array of segments connecting input image points to grid reprojections.
