Abstract: A work cycle monitoring system for a machine having a howl and an apron is provided. The work cycle monitoring system includes a perception sensor provided in association with the bowl of the machine. The perception sensor is configured to generate a signal indicative of a view of the bowl. The work cycle monitoring system also includes a controller coupled to the perception sensor. The controller is configured to receive the signal indicative of the view of the bowl from the perception sensor. The controller is configured to determine a position of the apron and a level of material within the bowl based on the received signal. The controller is further configured to identify a current stage of a work cycle of the machine based on the determined position of the apron and the determined level of the material.
