Abstract
A marker for remote localisation in a medium, the marker including a magnetic field sensor configured to measure three different magnetic fields at three different respective times in three dimensions at a marker location in the medium, wherein the marker is configured to generate measurement data representing the measured magnetic fields for determining the marker location.
Claims21
A marker for remote localisation in a medium including geological or building materials, the marker including:
- a housing for mechanically protecting the marker when embedded in the geological or building materials;
- a magnetic field sensor in the housing configured to measure three different magnetic fields at three different respective times in three dimensions at a marker location at three different respective orientations in the geological or building materials, wherein the marker is configured to generate measurement data representing the measured magnetic fields for determining the marker location when the three different magnetic fields are generated at the three different respective times with three different respective orientations by a magnetic source system (MSS) located outside the geological or building materials;
- and
- a chargeable power source in the housing for powering the magnetic field sensor.
A method for remote localisation in a medium including geological or building materials, the method including:
- generating three different magnetic fields at three different respective times in three dimensions with three different respective orientations outside the geological or building materials;
- using a magnetic field sensor, measuring the three different magnetic fields at the three different respective times in the three dimensions at a marker location at three different respective orientations in the geological or building materials;
- generating measurement data representing the measured magnetic fields for determining the marker location;
- using a chargeable power source, powering the magnetic field sensor;
- and
- mechanically protecting the magnetic field sensor and the chargeable power source in the geological or building materials with a housing around the magnetic field sensor and the chargeable power source.
