Reconstruction of 3-D Temperature Distribution for Combustion Flame Image
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 threedimensional 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 threedimensional 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.
