概要
|
In recent years, indoor and outdoor position information has been used in various services. The Global Positioning System (GPS) is most used to know position information. However, GPS cannot estimate the position indoors, where the signal from the satellite is difficult to receive. Thus, using the received signal strength indicator of iBeacon has been proposed. Beacon’s signals are in the 2.4GHz band, and the signal in the 2.4 GHz incurs the effect of a human body. Beacon’s signal passing through a human body is greatly attenuated. This causes errors in the estimation of the position. In this study, we reduce the error of the estimated position caused by a human body. the effect of the human body is reduced by using the displacement of the estimated distance to estimate the position. In addition, the accumulated error in position estimation using the displacement of the estimated distance is correct by detecting the passage of the receiver.
