摘要
射频识别技术RFID,利用无线电讯号通过非接触式双向通信进行信息交换,从而达到对目标身份的识取和物件路径的追踪,且其具有技术成熟、低成本、高精度等优点。描述RFID定位技术,对目前比较流行的算法以及相应的改进算法进行对比分析,指出目前还存在的一些问题。结论:相较于其他的几种无线定位技术(WiFi定位技术、蓝牙定位技术等),RFID定位技术的优势相当明显;但是,无论是经典的定位算法,还是基于基本理论改进的算法,应用在具体场景中时,精确度均存在较大差别,需视实际环境决定所应用的定位算法。
RFID（Radio Frequency Identification Technology）, uses radio signals to exchange information through non-contact two-way communication, so as to achieve the target identity tracking and identifying objects take the path. RFID technology is of maturity, low cost and high accuracy. RFID positioning technology is described, the current popular algorithms and corresponding improved algorithms are compared and analyzed, and some problems are also pointed out. Conclusion： Compared with several other wireless location technology （WiFi positioning technology, positioning technology Bluetooth, etc.）, the advantages of RFID positioning technology is fairly obvious; but whether it is the classic location algorithm, or based on the basic theory of the improved algorithm used in concrete scenario, the accuracy will be very different, depending on the localization algorithm practical environmental decision applications.
