Abstract
Systems and methods presented herein include a cable spooling system that includes a drum configured to rotate about a central axis of the drum to wind and unwind a cable onto and from the drum as the drum rotates. The cable spooling system also includes one or more cameras configured to capture images of the drum as it rotates. The cable spooling system further includes one or more markers disposed on one or more flanges of the drum. The one or more markers are configured to be in view of the one or more cameras during a portion of rotation of the drum. In addition, the cable spooling system includes a data processing and control system configured to estimate an angular velocity of the drum using the images captured by the one or more cameras.
