Abstract
A system and method are provided for determining the position and orientation of an implement on a work machine in a non-contact manner using machine vision. A 3D camera, which is mounted on the vehicle with a field of view that includes components on the implement (e.g., markers in some examples), determines a three-dimensional position in a local coordinate system of each of the components. A global positioning system in cooperation with an inertial measurement unit determines a three-dimensional position and orientation of the 3D camera in a global coordinate system. A computing system calculates a three-dimensional position in the global coordinate system for the components using the local three-dimensional positions of the components and the global three-dimensional position and orientation of the 3D camera. The position and orientation of the implement can then be calculated based on the calculated global three-dimensional positions of the components.
