RFID & vision based indoor positioning and identification system

RFID is the best choice for indoor positioning as it attaches equal importance to both accuracy and cost; however, with the limited strength stability of RFID signals, coupled with interferences of indoor environments and furniture, the positioning system based on RFID only is subject to bottlenecks, which are difficult to break through for positioning accuracy. Therefore, this paper presents an RV-based indoor positioning and identification system which integrating RFID and vision techniques, via cross reference of video images, RFID positioning, and ID information, improves the accuracy of personnel positioning and possesses the function of personnel identification.
