By means of image processing technique a simple and useful method for measuring two-dimensional flame temperature distribution is proposed which is based on Wien 's law of radiation and described fundamentally .

借助于计算机图象获取、处理技术，本文提出了一种简单有效 的全 炉膛火焰二维温度场分布计测方法。

Based on the Wien 's law temperature and emissivity of flame were obtained by processing the measured data with an optimization algorithm .

根据这一 特点， 从 维恩 公式 出发，利用最优化方法处理测得的火焰辐射光谱信号，得到了火焰 的温度和黑度。
