Parameters

objectPoints

Type: System.Collections.GenericIEnumerablePoint3f
Array of object points, 3xN/Nx3 1-channel or 1xN/Nx1 3-channel, where N is the number of points in the view.

rvec

Type: SystemDouble
Rotation vector (3x1).

tvec

Type: SystemDouble
Translation vector (3x1).

cameraMatrix

Type: SystemDouble
Camera matrix (3x3)

distCoeffs

Type: SystemDouble
Input vector of distortion coefficients (k_1, k_2, p_1, p_2[, k_3[, k_4, k_5, k_6]]) of 4, 5, or 8 elements. If the vector is null, the zero distortion coefficients are assumed.

imagePoints

Type: OpenCvSharpPoint2f
Output array of image points, 2xN/Nx2 1-channel or 1xN/Nx1 2-channel

jacobian

Type: SystemDouble
Optional output 2Nx(10 + numDistCoeffs) jacobian matrix of derivatives of image points with respect to components of the rotation vector, translation vector, focal lengths, coordinates of the principal point and the distortion coefficients. In the old interface different components of the jacobian are returned via different output parameters.

aspectRatio (Optional)

Type: SystemDouble
Optional “fixed aspect ratio” parameter. If the parameter is not 0, the function assumes that the aspect ratio (fx/fy) is fixed and correspondingly adjusts the jacobian matrix.
