Tracking

• Tracking systems used

  • Magnetic Tracking
    • Use Ascension Flock of Birds sensor
    • Calibration of magnetic tracker (field |? position)
    • Error, due to magnetic field distortion by metal objects
    • Correction
      • Measure distortion at each point with a sensor
      • Build mapping of distortions
      • Calculate correction factors & build 3D lookup table
