SYSTEM AND METHOD FOR HEAVY EQUIPMENT NAVIGATION AND WORKING EDGE POSITIONING

摘要

A system and method for automatically controlling working edges on a heavy equipment vehicle is provided. A GNSS/INS system determines a location of the vehicle. A vision system calculates a location of the working edge in a vision system coordinate system by obtaining images of a target connected to the working edge using a camera with a fixed field view that incorporates the relative movement of the target and determining the relative position of the target in the images. The location is then transformed to the navigation system coordinate system. The transformed location information is used by a working edge control system to control the placement of the working edge.

1. A system for controlling a working edge on a vehicle, the system comprising:
a navigation system configured to provide a location of the vehicle in a navigation system coordinate system; an image capture device with a fixed field of view configured to obtain one or more images of one or more targets operatively connected to the working edge; a vision system configured to determine location information, in a vision system coordinate system, of the working edge using the captured one or more images by determining relative locations of the one or more targets in the one or more images; and a processor configured to translate the location information from the vision system coordinate system to the navigation system coordinate system.
