| Abstract(in English) | There are many location-based services using GPS. For instance, navigating a car, navigating pedestrians using apps on smartphones and providing some information about nearby stores have already been provided. The services that can be used in both outdoor and indoor environments will be provided if those services are steadily expanded. Therefore, indoor location estimation methods using BLE beacons, which can be installed at low cost, have been actively researched and developed. But those methods are not practical because the operating costs such as pre-learning costs are high in order to realize a highly accurate estimation. In this paper, we propose a highly accurate location estimation method that suppresses the learning data acquisition cost. In the proposed method, the learning data collected in a part of the similar environment using the BLE beacon is corrected and interpolated by using the Kalman filter and the linear interpolation method, and the location is estimated using it. In addition, considering the versatility, we also try verification in different environments and show the effectiveness of the proposed method. |
