摘要

本文研究了在室内环境中使用可见光定位系统来提供三维(3D)高精度解决方案。所提出的系统利用了在发射器和接收器(Rx)分别使用单个发光二极管和图像传感器。该系统可以使用到达角度和接收信号强度(RSS)的组合来检索Rx的三维坐标。为了减轻透镜在Rx处引起的误差,提出了一种新的方法并进行了实验验证。作者表明,所提出的方法在所有情况下都优于先前报道的RSS,并且在250µs至4 ms的标准范围内不受不同暴露时间的影响。实验表明,该算法可以实现7.56 cm的三维均方根误差。

A unilateral 3D indoor positioning system employing optical camera communications

This article investigates the use of a visible light positioning system in an indoor environment to provide a three dimensional (3D) high-accuracy solution. The proposed system leveraged the use of a single light-emitting diode and an image sensor at the transmitter and the receiver (Rx) respectively. The proposed system can retrieve the 3D coordinate of the Rx using a combination of the angle of arrival and received signal strength (RSS). To mitigate the error induced by the lens at the Rx, a novel method is proposed and experimentally tested. The authors show that, the proposed method outperforms previously reported RSS under all circumstances and it is immune to varying exposure times within the standard range of 250 µs to 4 ms. The authors experimentally demonstrate that the proposed algorithm can achieve a 3D root mean squared error of 7.56 cm.
