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.
