Abstract:
To tackle the error accumulation problems of the foot-mounted inertial positioning systems, aiding measurements are often adopted to calibrate the inertial-generated raw trajectories. Currently, the calibration methods, although effective, still lack interior connection and unity. In this paper, a unified anchor based trajectory calibration framework is proposed. The concept of anchors is defined as different types of aiding information and is considered as different constraint conditions to the inertial-generated trajectory. The foundation of the framework is a particle filter, and different anchor information correspond to different particle weight updating strategy. The proposed framework is expansive to incorporated different types of anchors. We choose three representative anchors to elaborate the proposed framework and they are: Ultra-WideBand (UWB) ranging anchors, iBeacons and the building structure based virtual anchors. The results in simulations and real scenario tests have validated the effectiveness of the proposed anchor based framework in calibrating the inertial-generated raw trajectories.
