A spout identification module is adapted to identify a spout (e.g., or an associated spout position) of the harvesting vehicle in the collected image data. A relative motion detector detects the relative motion of a receiving vehicle and the harvesting vehicle or detects the relative motion between the spout and a container of the receiving vehicle. An alignment module is adapted to determine the relative position of the spout and the cells in the container via processing of the image data such that the spout is aligned with the longitudinal axis or a lateral offset from the longitudinal axis based on the detected relative motion and where a longitudinal size of the deadband volume is adjusted based on the relative motion.
