In this study, in order to investigate visibility in a smoke-filled environment like a firefight scene, a simulation system was constructed using a transmission model and a reflection model based on experimental data. Scattering and absorption of smoke layers as functions of wavelength and smoke characteristics are derived from analyzing transmission of smoke with Mie-theory. Reflections of object surface are obtained by applied experimental data to Sparrow's reflection model. With a result from the simulation, it shows good correspondence with real image, and scattering, absorption and reflection effect was clarified in visible and infrared image in a smoke-filled environment.
