Abstract
We present a novel solution to accurately recover 3D dynamic flame temperature field based on physical parameters consistency. First, a new optical model is proposed to establish the relationship between the flame radiation and the radiance field, this model fully considers refractive effect caused by refraction index changing; Second, high dynamic range (HDR) cameras are used to take flame images, a lookup table is employed calculate temperature from radiance; Third, an algorithm is put forward to reconstruct the flame temperature field. Experimental results on real flame accord with physical facts, which demonstrate that our solution is validate.
