FUNCTIONfisheye_projectPoints

RETURN TYPEvoid

Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Projects points using fisheye model

fisheye_projectPoints(objectPoints: Mat, imagePoints: Mat, rvec: Mat, tvec: Mat, K: Mat, D: Mat, alpha: number, jacobian: Mat): void;

objectPoints: Array of object points, 1xN/Nx1 3-channel (or vector<Point3f> ), where N is the number of points in the view.
imagePoints: Output destination, filled by the native operation. Output array of image points, 2xN/Nx2 1-channel or 1xN/Nx1 2-channel, or vector<Point2f>.
rvec: rvec argument (Mat).
tvec: tvec argument (Mat).
K: k argument (Mat).
D: Input vector of distortion coefficients \distcoeffsfisheye.
alpha: The skew coefficient.
jacobian: Output destination, filled by the native operation. Optional output 2Nx15 jacobian matrix of derivatives of image points with respect to components of the focal lengths, coordinates of the principal point, distortion coefficients, rotation vector, translation vector, and the skew. In the old interface different components of the jacobian are returned via different output parameters.

The function computes projections of 3D points to the image plane given intrinsic and extrinsic camera parameters. Optionally, the function computes Jacobians - matrices of partial derivatives of image points coordinates (as functions of all the input parameters) with respect to the particular parameters, intrinsic and/or extrinsic.
