报告内容tagoram: real-time tracking of mobile rfid tags to high-precision accuracy using cots devices (mobicom 2014, best paper award)

报告简介:in many applications, we have to identify an object and then locate the object to within high precision (centimeter- or millimeter-level). legacy systems that can provide such accuracy are either expensive or suffering from performance degradation resulting from various impacts, e.g., occlusion for computer vision based approaches.

in this work, we present an rfid-based system, tagoram, for object localization and tracking using cots rfid tags and readers. tracking mobile rfid tags in real time has been a daunting task, especially challenging for achieving high precision. our system achieves these three goals by leveraging the phase value of the backscattered signal, provided by the cots rfid readers, to estimate the location of the object.

we have implemented the tagoram system using cots rfid tags and readers. the system has been tested extensively in the lab environment and used for more than a year in real airline applications. for lab environment, we can track the mobile tags in real time with a millimeter accuracy to a median of 5mm and 7.29mm using linear and circular track respectively. in our year- long large scale baggage sortation systems deployed in two air- ports, our results from real deployments show that tagoram can achieve a centimeter-level accuracy to a median of 6.35cm in these real deployments.
