1. An excavator comprising:
a rotatable house; a bucket operably coupled to the house; an inertial measurement unit (IMU) operably coupled to the excavator and configured to provide an IMU signal indicative of rotation of the house;
a backup camera disposed to provide a video signal relative to an area behind the excavator;
a controller coupled to the IMU and operably coupled to the backup camera through a vision system separate from the controller, the controller being configured to receive the IMU signal from the IMU and to determine a position of the bucket based on a combination of the IMU signal and a motion signal based on analysis of successive images from the backup camera; and
wherein the vision processing system is configured to provide the motion signal in the form of a motion vector based on analysis of successive images from the backup camera.
