Aidloc: an Accurate Acoustic Indoor Localization System
نویسندگان
چکیده
We present Aidloc, an acoustic indoor localization system based on acoustic ranging which is very convenient for smartphone positioning. An Aidloc demo system consists of 5 acoustic beacons and a smartphone. Beacons are deployed in different hight to establish a beacon space. This gives a 3D relative coordinate for 3D target localization. A combined localization approach of TDOA and TOA is used. According to our experiment in office scenario, the localization error is observed to be less than 20cm.

Improving Indoor Positioning Via Mobile Sensing
Accurate indoor position and movement information of devices enables numerous opportunities for location based services. GPS provides accurate localization results in an outdoor environment, however, GPS cannot be applied indoors pervasively due to the various interferences. Although extensive research has been dedicated to this field, accurate indoor location information remains a challenge wi...
متن کاملTowards Fine-grained Smartphone Localization via Low-complexity Anchors
To enable indoor location-based services (ILBS), there are several stringent requirements for an indoor localization system: highly accurate that can differentiate massive users’ locations without site-survey; no additional hardware components or extensions on users’ smartphones; scalable to massive concurrent users. In this paper, we propose a practical and accurate smartphone localization sol...
متن کاملReverberation-robust acoustic indoor localization
We propose an effective approach to acoustic indoor localization that works in reverberant environments. The proposed localization system has been implemented to operate in an inaudible frequency range for practical applications. In order to achieve high performance, we propose an effective acoustic source data structure with a synchronization algorithm. To evaluate the proposed system, series ...

We propose and implement a novel indoor localization scheme, Swadloon, built upon an accurate acoustic direction finding. Swadloon leverages sensors of the smartphone without the requirement of any specialized devices. The scheme Swadloon does not rely on any fingerprints and is very easy to use: a user only needs to shake the phone for a short duration before walking and localization. Our Swad...
