| Popis: | A novel indoor positioning method is proposed, enhancing the conventional pedestrian dead-reckoning (PDR) with the received signal strength indicator (RSSI)-based heading correction. PDR is reliable for steadily accurate positioning if its heading error can be rectified. Upon detecting a long straight trajectory estimated by PDR, the PDR-estimated headings shall be updated by headings derived based on RSSI data and linear regression. The proposed method had been tested in real complex indoor environments with varying density and availability of RSSI sources, and benchmarked against some existing methods in terms of positioning accuracy. The experiment results are presented to demonstrate the feasibility of the proposed method. |
