Abstract: A location tracking system is provided to track the location information and attribution information of an object by sensing the location of the object to which an RFID(Radio Frequency IDentification) is attached. A location tracking system includes an RFID reader(110), cameras(120a-120n), an image processing module(130) and a middleware(140). The RFID reader communicates with an RFID tag to read out data stored at the RFID tag. The plural cameras installed at in the location photographs an object to which the RFID tag is attached. The image processing module separates an object shape from a background image in a two dimensional image screen and arranges the image at each frame. The middleware integrates the object data transmitted from the RFID reader and the image processing module.
