Abstract: A sensor calibration method and system dynamically compute a bias offset which is subtracted from field strength readings generated by a sensor to correct them. The three-dimensional space around a sensor is seeded with orientation targets. As the sensor is rotated to different orientations, field strength readings are generated by the sensor and assigned to different targets based on estimated proximity. Once occupancy of targets conforms to a first state of occupancy, a coarse bias offset is computed for the sensor using readings from occupied targets. Once occupancy of targets conforms to a second state of occupancy, a refined bias offset is computed for the sensor using readings from occupied targets. Multiple sensors may be calibrated concurrently. Moreover, a user interface provides a real-time graphic showing the location and occupancy status of individual targets and highlighting the individual target best aligned with a most recent corrected sensor reading.
