Abstract

Indoor localization is crucial for developing intelligent environments capable of understanding user contexts and adapting to environmental changes. Bluetooth 5.1 Direction Finding is a recent specification that leverages the angle of departure (AoD) and angle of arrival (AoA) of radio signals to locate objects or people indoors. This paper presents a set of algorithms that estimate user positions using AoA values and the concept of the Confidence Region (CR), which defines the expected position uncertainty and helps to remove outlier measurements, thereby improving performance compared to traditional triangulation algorithms. We validate the algorithms with a publicly available dataset, and analyze the impact of body orientation relative to receiving units. The experimental results highlight the limitations and potential of the proposed solutions. From our experiments, we observe that the Conditional All-in algorithm presented in this work, achieves the best performance across all configuration settings in both line-of-sight and non-line-of-sight conditions.

基于到达角的室内定位算法与基准比较

室内定位对于开发能够理解用户背景并适应环境变化的智能环境至关重要。蓝牙 5.1 测向技术是最近推出的一种技术规范，它利用无线电信号的离去角（AoD）和到达角（AoA）来定位室内的物体或人员。本文介绍了一套利用 AoA 值和置信区域 (CR) 概念估算用户位置的算法，CR 定义了预期位置的不确定性，有助于去除离群测量值，从而与传统三角测量算法相比提高性能。我们利用一个公开的数据集对算法进行了验证，并分析了相对于接收单元的身体方位的影响。实验结果凸显了所提解决方案的局限性和潜力。我们从实验中发现，在视距和非视距条件下，本研究提出的条件全进算法在所有配置设置中都达到了最佳性能。
