最近，室内位置估计的研究因跟踪商店中的人的行为而引起人们的关注。以商店为例，室内位置估计采用绝对位置估计技术，利用商店中安装的信标的 WiFi 或 BLE 信号的 RSSI。由于RSSI受到信号反射、绕射、遮挡等因素的影响，在将RSSI值转换为距离的过程中，估计值可能会产生误差。在本文中，我们提出了动态和最优的信标选择方法，以尽量减少静态和可移动障碍物对无线信号屏蔽的影响。仿真结果表明，与仅考虑静态障碍物的方法相比，使用我们提出的方法的平均位置估计误差减少了 1.2m，并且无论选择的 BLE 信标数量如何，我们的方法都保持恒定的误差。
Recently, research of indoor location estimation has been attracting attention for tracking behaviors of human in a store. In the case of the store, indoor location estimation adopts absolute location estimation techniques using RSSI of WiFi or BLE signals from beacons installed in the store. As the RSSI has been influenced by the signal reflection, the diffraction, the shelter and others, an estimated values can cause errors during the process of converting the RSSI values into distances. In this paper, we propose dynamical and optimal beacon selection method to minimize affections of wireless signal shielding by the static and movable obstructions. As the result of a simulation, we found that the average of the location estimation errors using our proposed method is reduced by 1.2m against a method only considering static obstructions and our method keeps a constant error regardless of the number of selected BLE beacons.
