StereoCalibration

While the calibration is running, this node indicates the approximate state of completion of the stereo calibration, i.e. the calibration of the camera’s extrinsic parameters. This node is also used to report the progress of a link calibration.

Number

A floating point number between 0 and 1 indicating the approximate completion of the step. The value 1 indicates that the step is complete.

Note

Because of the nature of the numerical optimization used in the calibration process, it is not possible to determine the progress precisely. The computed approximate progress percentage is based on the ratio of current optimization step size versus the desired model accuracy. The percentage might therefore drop to lower values multiple times during the computation. This does not indicate a problem or failure in the calibration.
