<p>A system for sensing a hybrid type magnetic based position and an impedance-based position, and a sensing method therefor are provided to improve correctness of a magnetic position sensor and to reduce a cost of impedance sensing by coupling a magnetic position measured value and an impedance position measured value to each other by using a hybrid type probe. A method for sensing a hybrid type magnetic-based position and an impedance-based position includes the steps of: injecting a probe, which includes a magnetic field transformer and at least one probe electrode, into a hollow of an object body(66); measuring a position coordinate of the probe at a location of the object body based on the magnetic field transformer(68); measuring an impedance between at least one probe electrode and at least one point of the surface of the object body(70); and correcting the measured impedance based on the measured position coordinate value(72-86).</p> |
