The study is concerned with developing a fast 3D imaging method for sparks and so using digital camera from a few projections. The point of this method is rapidly to reconstruct 3D images form a few projections, using the Singular Value Decompositions and the sampling model object.The first, we investigated a new algorithm by using the SVD.The results of computer simulation experiments based on the algorithm were good. We obtained good conditions between reconstructing parameters. The second, we tried to design hardware and software interface with a digital camera, and aucceeded in acquisition of emission images from flames. The third, we experimented with the reconstruction algorithm, and succeeded in 3D imaging for flames. The 3D images reconstructed were good. Several experiments made it obvious that there is a possibility that the reconstruction method will come into practical use.

这项研究致力于开发一种快速的火花3D成像方法，从而使用数码相机从几个投影中获得火花。该方法的重点是利用奇异值分解和采样模型对象快速地从几个投影重建三维图像。首先，我们研究了一种新的基于支持向量机的算法，基于该算法的计算机仿真实验结果良好。我们得到了重构参数之间的良好条件。其次，尝试设计了与数码相机的硬件和软件接口，成功地实现了火焰发射图像的采集。第三，对重建算法进行了实验，并成功地对火焰进行了三维成像。重建的3D图像效果良好。几个实验表明，这种重建方法有可能进入实际应用。
