基于图像的启发式三维火焰重建算法
Heuristic 3D flame reconstruction from images
摘要
Abstract
The flame reconstruction was studied, and an image-based heuristic 3D flame reconstruction approach was proposed to improve the reconstruction accuracy of the existing sparse-view tomography methods. The presented heuristic approach uses an energy constraint model to reconstruct 3D flame temperature. The approach allows complex image models to be applied to the reconstruction to make the rendering process closer to the real flame image formation process. Through the smoothness constraints to data, the reconstruction results were optimized. During the iterative process of the reconstruction, heuristic rules and GPU (graphics processing unit) were exploited to accelerate the reconstruction. The outcome of the experiments on both simulated data and captured data showed that, the proposed approach enhanced the precision and smoothness of the reconstruction compared with the existing methods.关键词
