The calibration command does not return a value, but as it will take some time to complete it publishes progress information under this node during execution.

As the calibration is based on numerical optimization, its run time and progress are not precisely predictable. The run time mostly depends on the number of chessboards used for calibration. Additionally the quality and variety of chessboard poses, the stereo configuration and the camera’s focal lengths affect the convergence behavior and speed.
