商品描述

RFID tag location in a 3D environment is investigated. The location of the tag with unknown coordinates can be estimated with certain accuracy. However, accuracy can be improved using the knowledge based on measurement of additional reference tags with known location. This book studies the mathematical formulation and practical realization of location sensing using RFID tags. Deviating from the standard use of RFID technology which employs one tag reader to identify presence of tag, multiple tag reader with known location are used to estimate the physical location of an individual tag, with/without the help of few reference tag with known location. Additionally, concept of trilateration has also been extended for tracking the tag on unknown location without use of reference tags. It was demonstrated that both approaches were proved to be cost-effective technique and estimation of the location of a specific tag has been achieve with sufficient accuracy.

商品描述(中文翻譯)

本書探討在三維環境中的RFID標籤定位。可以以一定的準確度估計未知坐標的標籤位置。然而,通過測量具有已知位置的附加參考標籤的知識,可以提高準確度。本書研究了使用RFID標籤進行位置感知的數學形式化和實際實現。

與標準的RFID技術不同,該技術使用一個標籤讀取器來識別標籤的存在,本書使用具有已知位置的多個標籤讀取器來估計單個標籤的物理位置,可以有或沒有幾個具有已知位置的參考標籤的幫助。此外,三角測量的概念也被擴展用於追踪未知位置的標籤,而無需使用參考標籤。實驗證明,這兩種方法都是具有成本效益的技術,可以以足夠的準確度估計特定標籤的位置。
