- Abstract
- At the National Research Institute of Fire and Disaster in Japan, data to improve the technology of fire detection have been gathered by performing physical and chemical analyses of the particles and gases emitted from fires and information about the electromagnetic spectrum. The products of combustion and electromagnetic waves are generated early in a fire of organic substances such as paper, lumber and plastics, which are present in many actual building fires. For this study, a new video camera system is proposed to monitor the light radiated from the fire source. The video camera system named 'Multi-Spectrum Camera System' is capable of monitoring and recording infrared, visible, and ultraviolet wavelengths without parallax and time delay. Image processing is used to extract the fire source from the total infrared image, as a basis for detecting the fire. A concept for smoldering fire detection is also discussed.
