Abstract
A magnetic beacon and inertial sensor system for precise indoor localization is provided using active magnetic beacons, magnetometers and inertial measurement units. The system is designed to work in environments that are not conducive to radio frequency (RF) (such as GPS, cell, Wi-Fi, or Bluetooth) or optical techniques (CCTV, IR), such as inside heavy industrial plant settings, underground or underwater.
Claims16
A magnetic beacon and inertial sensor system comprising:
- a plurality of magnetic beacons each outputting a discrete signal, each of the plurality of magnetic beacons being positioned in a predetermined position within a map;
- a portable integrated magnetometer and inertial measurement unit (PIMIMU) device, the PIMIMU device determining its location and outputting a location signal;
- and
- a controller or computing device is configured to determine the location of the PIMIMU device within the map based on information from the plurality of magnetic beacons, the controller further configured to determine the location of the PIMIMU device based on the information from the plurality of magnetic beacons and the location signal and outputting a location of the PIMIMU device.
