AI summary

An image-based position assessment method is performed in conjunction with a mechanism onboard an agricultural machine and containing a traveling component. In embodiments, the method includes receiving, at an image processing system, camera images captured by a diagnostic camera mounted to the agricultural machine. A field of view of the diagnostic camera at least partially encompasses an intended motion path along which the traveling component is configured to travel. The image processing system analyzes the camera images to determine whether a recorded time-dependent component position of the traveling component deviates excessively from an expected time-dependent component position of the traveling component, as taken along the intended motion path. The image processing further generates, or causes generation of, a first notification on a display device indicating that a positional adjustment to the traveling component is recommended if the recorded time-dependent component position deviates excessively from the expected time-dependent component position.
