Abstract: A positioning system and a positioning method based on radio frequency identification techniques (RFID) are provided. The positioning system includes in-vehicle devices, RFID readers and a server. The in-vehicle devices each includes a positioning device, an image capturing device and an image recognition module. The positioning device obtains a positioning location. The image capturing device captures a driving image. The image recognition module identifies adjacent vehicles, adjacent license plate information, and road attributes, and calculates relative location information. Each of the RFID readers reads a vehicle tag of one of the vehicles passing by, so as to mark a reference vehicle and generate reference vehicle information. A positioning adjustment module of the server determines whether the target vehicle is a reference vehicle, has been the reference vehicle or is a non-reference vehicle, and adjusts the positioning location of the target vehicle in different ways, accordingly.
