초록

An apparatus which remotely visualizes and detects toxic, flammable and other gas leaks and enables one to see gas clouds in real-time. A dual band thermal imaging infrared video camera fitted with a special filter images gas clouds. Image processing is utilized to develop and colorize the gas cloud information for display. The gas image is superimposed over a background image provided by a co-located visible light video camera.
