Positioning of vehicles is important for ITS. In a tunnel environment, most positioning solutions based on GPS sensors or ordinary cameras will fail. For positioning we propose a method to detect emergency telephone indicators in a tunnel environment by using infrared cameras. The proposed detection method makes use of both appearance and motion information of the target objects. By optimizing the detecting pipeline, the method works in real time and produced 100 % detection rate and 0 % false alarm rate in one of our experiments.
