基于计算层析成像的火焰三维重建算法研究

Aiming at the 3D reconstruction of flames based on computed tomography,this work proposes a new algorithm:the multiplicative algebraic reconstruction technique with non-local means(MART-NLM)filtering algorithm. By comparing it with existing algorithms,it is found that MART-NLM has better reconstruction accuracy,can effectively suppress noise and artifacts,and improve the reconstruction quality of flame front. Even with a 5° angle error and 5% Gaussian noise,the flame contour can still be reconstructed with good robustness.
