Developing Indoor Localization Method Based on Wireless LAN and Sensors

我们开发了一种基于WiFi信号强度和用户智能手机加速度计的通门检测方法。门划分了房间和走廊等物理区域。因此，他们的WiFi环境往往会有很大的差异。反过来说，在WiFi环境发生较大变化的点上，应该存在一个gate。我们将这个点定义为“WiFi重要点”。我们提出了基于WiFi距离函数和根据加速度计估计移动距离的检测方法。对提出的方法进行了评估，发现可以检测出一半以上的门通过。我们还发现，门的存在，可以估计相同的门通过具有很高的精度

We have developed a gate passing detection method based on WiFi signal strength and accelerometer of the user’s smartphone. Door divides physical areas such as room and hallway. Thus, the WiFi environments of them tend to vary on a large scale. Conversely, it can be said that a gate should exist when the point that the WiFi environment varies on a large scale. We define such point “WiFi Significant Point.” We propose the detection method based on WiFi distance function and estimated moving distance according to accelerometer. We evaluated the proposal method and found out that more than half part of door passing can be detected. We also found that the existence of doors that can be estimated same door passing with a high degree of accuracy
