Abstract
A system and method for determining the center and radius based on a least squares approach is disclosed. In one embodiment, a farmer drives through a given arc of a circular field in question and periodically takes position measurements. In another embodiment, a Least-Squares Algorithm is used to estimate the best-fitting center and radius given the set of position measurements input by the farmer.
Claims31
A method of determining the center point of rotation of a moveable dispenser, said dispenser having at least one path created by its wheels, comprising:
- providing a position determination system mounted on a vehicle;
- driving said vehicle along a portion of said path created by said dispenser movement;
- collecting position data for said vehicle along said portion of the path;
- processing said position data to determine the center of rotation of said moveable dispenser by a method of least squares.
A system of determining the center point of rotation of a moveable dispenser comprising:
- a dispenser having at least one path created by its wheels;
- a position determination system mounted on a vehicle, wherein said vehicle is to move along a portion of said path created by said dispenser movement;
- and,
- a processor in communication with said position determination system, said processor to,
- collect position data for said vehicle along said portion of the path, and
- process said position data to determine the center of rotation of said moveable dispenser by a method of least squares.
A system of determining the center point of rotation of a moveable dispenser comprising:
- a dispenser having at least one path created by its wheels;
- a position determination means coupled to a vehicle to collect position data for said vehicle while said vehicle moves along a portion of said path created by said dispenser movement;
- and
- processing means to determine the center of rotation of said moveable dispenser using a method of least squares.
