| Module: | Calibration | 
|---|
Finds the camera intrinsic parameters from the input arrays of image and real-world coordinates. Uses pinhole camera model (perspective camera).
Applications
Camera calibration, image to world coordinates transformations.
| Name | Type | Range | Description | |
|---|---|---|---|---|
![]()  | 
				inImagePoints | Point2DArrayArray | Array, for each view: array of 2D points of the calibration pattern, in the picture. | |
![]()  | 
				inWorldPlanePoints | Point2DArrayArray | Array, for each view: array of 2D points of the calibration pattern, in a world coordinate plane. | |
![]()  | 
				inImageWidth | Integer | 1 - ![]()  | 
				Image width, used for initial estimation of principal point. | 
![]()  | 
				inImageHeight | Integer | 1 - ![]()  | 
				Image height, used for initial estimation of principal point. | 
![]()  | 
				inDistortionType | LensDistortionModelType | Lens distortion model | |
![]()  | 
				inImagePointsStandardDeviation | Real | 0.0 - ![]()  | 
				Assumed uncertainty of inImagePoints. Used for robust optimization and outCameraModelStdDev estimation. | 
![]()  | 
				inFocalLength | Real* | 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]. | |
![]()  | 
				outCameraModel | PinholeCameraModel | ||
![]()  | 
				outCameraModelStdDev | PinholeCameraModel | Standard deviations of all model parameters, assuming that inImagePoints positions have a standard deviation equal to inImagePointsStandardDeviation. | |
![]()  | 
				outRmsError | Real | Final reprojection RMS error, in pixels. | |
![]()  | 
				outMaxReprojectionErrors | RealArray | For each view: the maximum reprojection error among all points. | |
![]()  | 
				outReprojectionErrorSegments | Segment2DArrayArray | For each view: array of segments connecting input image points to reprojected world points. | |
