Object Recognition Using 3D tag-based RFID System

RFID (radio frequency identification) technology has been rapidly and widely applied to various applications. Recently, RFID has been suggested as technology that supports object recognition. This paper introduces the advanced RFID-based recognition. The proposed RFID system not only identifies the existence of the object, but also estimates object´s orientation and location. These characteristics considerably reduce the dependence on other sensors which are required for recognizing objects. In this paper, we analyze the characteristics of our system and present a novel tag named a 3D tag. The estimation methods of location and orientation using the system are discussed
