CV_CALIB_USE_INTRINSIC_GUESS cameraMatrix contains valid initial values of fx, fy, cx, cy that are optimized ecs – Output vector of translation vectors estimated for each pattern view.ĭifferent flags that may be zero or a combination of the following values.That is, each k-th rotation vector together with the corresponding k-th translation vector (see the next output parameter description) brings the calibration pattern from the model coordinate space (in which object points are specified) to the world coordinate space, that is, a real position of the calibration pattern in the k-th pattern view (k=0. Otherwise, (cx, cy) is initially set to the image center ( imageSize is used), and focal distances are computed in a least-squares fashion. ![]() ![]() CV_CALIB_FIX_PRINCIPAL_POINT The principal point is not changed during the global optimization.Note, that if intrinsic parameters are known, there is no need to use this function just to estimate extrinsic parameters.
