Module: | Calibration |
---|
Finds the telecentric camera intrinsic parameters from the input arrays of image and real-world coordinates.
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. | |
outCameraModel | TelecentricCameraModel | |||
outCameraModelStdDev | TelecentricCameraModel | Standard deviations of all model parameters, assuming that inImagePoints positions are disturbed with gaussian noise with 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. |
