摘要

为了提高室内定位精度

实现三维定位

文章提出了一种基于单个发光二极管（LED）的室内反向定位系统。该定位系统解决了利用多个LED定位时的干扰问题

其将日常所用的白光LED作为光源

既与实际情况相符

又便于将来推广使用。该定位系统根据接收机接收到的光照度来估算距离

以残差平方和最小为目标函数拟合出最佳回归曲线

再利用三边定位原理以及空间几何关系确定接收机坐标。实验结果表明

在实际应用场景中

该定位系统能够实现准确的室内定位服务。

Abstract

In order to improve the indoor positioning accuracy and realize three-dimensional positioning

this paper proposes an indoor reverse positioning system using a single Light Emitting Diode（LED） lamp. This positioning system solves the problem of interference in positioning by using multiple LED light sources. The system takes the white LED light used by people in daily life as the light source

which is not only consistent with the actual situation

but also convenient for future promotion. The system estimates the distance according to the illuminance received by the receiver

and fits the optimal regression curve with the minimum residual sum of squares as the objective function. Then we use the triangulation principle and the spatial geometric relationship to determine the receiver coordinates. The experimental results show that the positioning system can realize accurate indoor positioning service in practical application scenarios.
