AVS.CalibrateCamera_Pinhole Method
Finds the camera intrinsic parameters from calibration grids. Uses pinhole camera model (perspective camera).
Namespace: | AvlNet |
---|---|
Assembly: | AVL.NET.dll |
Syntax
public static void CalibrateCamera_Pinhole ( IList<IList<AvlNet.AnnotatedPoint2D>> inImageGrids, int inImageWidth, int inImageHeight, AvlNet.LensDistortionModelType inDistortionType, float inImagePointsStandardDeviation, float? inFocalLength, AvlNet.PinholeCameraModel outCameraModel, NullableRef<AvlNet.PinholeCameraModel> outCameraModelStdDev, NullableValue<float> outRmsError, NullableRef<List<float>> outMaxReprojectionErrors, NullableRef<List<List<AvlNet.Segment2D>>> outReprojectionErrorSegments )
Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
inImageGrids | System.Collections.Generic.IList<System.Collections.Generic.IList<AvlNet.AnnotatedPoint2D>> | For each view, the annotated calibration grid. | |||
inImageWidth | int | <1, INF> | Image width, used for initial estimation of principal point. | ||
inImageHeight | int | <1, INF> | Image height, used for initial estimation of principal point. | ||
inDistortionType | AvlNet.LensDistortionModelType | Polynomial | Lens distortion model. Default value: Polynomial. | ||
inImagePointsStandardDeviation | float | <0.0f, INF> | 0.1f | Assumed uncertainty of inImagePoints. Used for robust optimization and outCameraModelStdDev estimation. Default value: 0.1f. | |
inFocalLength | float? | 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: atl::NIL. | |||
outCameraModel | AvlNet.PinholeCameraModel | ||||
outCameraModelStdDev | AvlNet.NullableRef<AvlNet.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. | |||
outRmsError | AvlNet.NullableValue<float> | Final reprojection RMS error, in pixels. Can be null to skip this parameter calculation. | |||
outMaxReprojectionErrors | AvlNet.NullableRef<System.Collections.Generic.List<float>> | For each view: the maximum reprojection error among all points. Can be null to skip this parameter calculation. | |||
outReprojectionErrorSegments | AvlNet.NullableRef<System.Collections.Generic.List<System.Collections.Generic.List<AvlNet.Segment2D>>> | For each view: array of segments connecting input image points to grid reprojections. Can be null to skip this parameter calculation. |
