Abstract(in English) With the extension of O2O (Online to Offline) services, achieving indoor positioning for obtaining the position of the smartphone to the low cost and high accuracy indoors is required. Among them, since a large number of smartphones are standard support Bluetooth, it is more established BLE (Bluetooth Low Energy) tags indoors, using a received signal strength of the radio signal is periodically transmitted from the BLE tag to smartphones. Their techniques for estimating its position is noted. Although techniques for realizing the indoor positioning using a received signal strength may be roughly divided into trilateration method and fingerprinting technique, in view of hardly affected by the reflection of radio waves in the indoor environment, the fingerprinting technique are attracting attention. Fingerprinting technique is learned in advance and indoor positional relationships of the received signal strength, when the position measurement is to specify the position by performing a comparison between the training phase of the data. Therefore, for example, like the indoor layout is changed, if the training phase and environmental changes, in order to influence the relationship between the position and the radio wave strength, the accuracy of positioning there is a problem of decrease. In this paper, we propose a method to solve this problem. Specifically, from among a plurality of radio signals received, and the position to that reached the smartphone directly from BLE tags, which identifies to that reached after being reflected on the wall surface or the like, it is reached by the reflected By excluding the time of positioning, to increase the robustness of the positioning accuracy.
