Combustion flame detection based on digital image processing is the popular trend of flame detection technology. In this paper, we propose a modeling method for the distribution of three-dimensional temperature field of combustion flame image based on modified simultaneous algebraic reconstruction technique. The flame image captured by CCD is projected onto the target sheet in three-dimensional space. We investigate the relationship between each pixels of flame image and spatial flame radiation intensity according to the spatial flame radiation of three-dimension. Using the method of reconstruction image based on projection, the simultaneous algebraic reconstruction technique (SART) and the least squared estimation (LSE) algorithm are used to calculate the three-dimensional (3D) temperature field distribution. Numerical calculation and simulation experiments have been done in order to verify the algorithm. The experimental results demonstrated that the algorithm is feasible and effective.
