摘要

利用可见光进行室内定位已经引起了世界各国的广泛关注。基于可见光的室内定位方案受到环境中安装多个LED灯的限制。为了克服这一限制，我们提出了一种仅使用一个LED灯的新型室内定位系统，其中使用智能手机作为接收器，通过接收信号强度(RSS)和到达角(AOA)定位算法来估计三维(3-D)位置。实验结果表明，在2 m × 2 m × 2.5 m的室内环境下，该系统的平均定位误差约为10.2 cm。

A RSS/AOA based indoor positioning system with a single LED lamp

Indoor positioning using visible light has attracted great attentions in the world. The reported indoor positioning schemes based on visible light are limited by installing multiple LED lamps in the environments. In order to overcome this limitation, we propose a novel indoor positioning system using only one LED lamp, in which a smartphone is used to be receiver to estimate the three-dimension (3-D) position by using the received-signal-strength (RSS) and angle-of-arrival (AOA) positioning algorithm. The proposed system is demonstrated by experiment and the results show that ~10.2-cm average positioning error is achieved in a 2 m × 2 m × 2.5 m indoor environment.
