Paper Abstract

We present a novel solution to accurately recover three-dimensional dynamic flame temperature field. Traditional flame temperature field reconstruction schemes take flame images with general industrial cameras and reconstruct flame temperature field under the assumption that the cameras can capture the full spectrum. However, the dynamic range of the general industrial camera is more restricted than that of the light from flame and camera response band is much narrower compared with the full spectrum. In this paper, we use high dynamic range to take flame images and reconstruct the flame radiant existence field on camera response band. Temperature field is calculated from radiant existence field via lookup table between them. Experimental results on real flame demonstrate that our approach is accurate and easy to implement. The rendering results of the flame-based temperature field accord with physical facts.
