为了适应非对称火焰三维温度分布测量的需要，发展了一种三维重构算法。该算法既有别于医学成像和机械探伤等领域常用的变换法，便于在算法中加入火焰的某些先验信息，又不同于通常的有限级数扩展法，具有较快的运算速度，从而可以减少三维重构误差。采用这一算法在保证一定精度的前提下，可通过少投影实现火焰的三维温度分布测量。仿真运算及实验结果均证明此算法是可行的。
In order to meet the need of asymmetric flame three-dimensional temperature distribution measurement, a three-dimensional reconstruction algorithm is developed. The algorithm is different from the commonly used transformation methods in fields such as medical imaging and mechanical flaw detection, and is convenient for adding some prior information of the flame into the algorithm and is different from the usual finite-sequence expansion method, so that the algorithm has a faster computing speed Can reduce the three-dimensional reconstruction error. Using this algorithm to ensure the accuracy of a certain premise, through the lack of projection flame three-dimensional temperature distribution measurement. Simulation and experimental results show that this algorithm is feasible.
