Abstract
Methods and systems for tracking a magnetic object are disclosed. A plurality of line segments can be complied based on data received from a plurality of magnetic sensors. The line segment that minimizes an error thereof can then be determined. The path of a magnetic object can then be established based on the compiled line segments and calculated error thereof, thereby permitting the magnetic object to be tracked according to the data received from the magnetic sensors, which can be based on the closest of approach of one or more of the magnetic sensors to the magnetic object. The present invention can thus permit a magnetic object to be tracked utilizing the total magnetic field measured at a position of closest approach by the magnetic object to one or more magnetic sensors from among a group of magnetic sensors.
