Tunnel Disaster Prevention System Employing image Processing Technology

摘要

In the field of road traffic, closed-circuit television (CCTV) cameras installed at the roadsides are used in many cases to perform traffic flow surveillance and road environment maintenance and management. Sumitomo Electric Industries, Ltd. (SEI) has been developing a variety of image processing systems for many years, aiming at improving the efficiency of surveillance with CCTV images. Though such systems that capture the images of running vehicles are the mainstream of this technology field, the application of this technology to surveillance and measurement of road environment conditions is expanding year by year. As one of such new applications of image processing technology in the field of road traffic, this report describes the tunnel disaster prevention system that employs the algorithm SEI has developed to detect fire (flame or smoke) inside the tunnel.
