Abstract

Abstract Indoor positioning has attracted much research effort due to many potential applications such as human or object tracking and inventory management. Whilst there are a number of indoor positioning techniques and algorithms developed to improve positioning estimation, there is still no systematic way to characterise the estimation. In this paper, we propose a method comprising of three characteristics to characterise indoor positioning estimation. We conducted experiments on an active radio frequency identification (RFID)-based real-time location system in different environmental conditions. We used both a human and a robot to traverse two experimental areas and collected positioning results at different fixed points along the traversal path. Using this basic positioning data, we were able to characterise positioning estimation using three characterisations: position accuracy, centroid consistency and angular distribution. We demonstrate the use of these characteristics for examining different points in a travelling path and different measurements.

利用基于有源射频识别的实时定位系统的实验数据表征室内定位估计
摘要室内定位由于其在人体或物体跟踪、库存管理等方面的潜在应用而引起了广泛的研究。虽然已经开发了许多室内定位技术和算法来改进定位估计,但仍然没有系统的方法来表征估计。本文提出了一种包含三个特征的室内定位估计方法。我们在不同的环境条件下对基于有源射频识别(RFID)的实时定位系统进行了实验。我们使用人和机器人分别穿越两个实验区,并在穿越路径的不同固定点收集定位结果。使用这些基本的定位数据,我们能够使用三个特征来描述定位估计:位置精度、质心一致性和角度分布。我们演示了使用这些特性来检查旅行路径和不同测量中的不同点。

期刊介绍: The aim of this interdisciplinary and international journal is to provide a forum for the exchange of original ideas, techniques, designs and experiences in the rapidly growing field of location based services on networked mobile devices. It is intended to interest those who design, implement and deliver location based services in a wide range of contexts. Published research will span the field from location based computing and next-generation interfaces through telecom location architectures to business models and the social implications of this technology. The diversity of content echoes the extended nature of the chain of players required to make location based services a reality.
