cvProjectPoints


Module: OpenCV

Projects 3D points to an image plane.

Name Type Description
Input value inObjectPoints Point3DArray Array of object points expressed with respect to the world coordinate frame.
Input value inRVec Vector3D The rotation vector (Rodrigues) that, together with inTVec, performs a change of basis from world to camera coordinate system.
Input value inTVec Vector3D The translation vector.
Input value inCameraMatrix Matrix Camera intrinsic matrix.
Input value inDistCoeffs Matrix* Input vector of distortion coefficients.
Input value inAspectRatio Real* 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.
Output value outImagePoints Point2DArray Output array of image points.
Output value outJacobian Matrix 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.
