Magnetic disturber detection method and detector, object-localizing method and system, recording medium for these methods

摘要

Detection method involves determining, from magnetic field measured by sensor (26,28), coordinates of direction vector collinear with axis (14,16) passing through geometrical center of emitter (10) and geometrical center of sensor. Geometrical center of emitter is the point at which there is located a magnetic field point source that models the emitter for each sensor. Sensor is capable of being modeled by a point transducer situated at a point in which magnetic field is measured and constituting the geometrical center of sensor. Independent claims are included for the following: (1) a method for localizing an object in a referential system; (2) a computer-readable medium having encoded thereon software for detecting a magnetic disturber of an at least triaxial emitter of a magnetic field; (3) a detector of a magnetic disturber of a magnetic field emitted by a magnetic field emitter that is at least triaxial; and (4) a system for localizing an object in a referential system.
