Three dimensional visualisation and reconstruction of the luminosity distribution of a flame using digital imaging techniques

This paper presents an algorithm for the three-dimensional (3D) visualisation and luminosity reconstruction of a combustion flame. A combination of image processing techniques and filtered-back projection algorithms is employed to reconstruct grey-scale sections of the flame from three 2D images taken by three identical CCD monochromatic cameras placed around the flame. The technique proposed is capable of reconstructing both cross- and longitudinal sections of the flame, and consequently a complete 3D luminous model of the flame.
