摘要
由彩色ＣＣＤ获取的火焰图像包含红、绿、蓝三色亮度值。通过试验和理论的分析，提出了一种不需参考点而直接利用彩色ＣＣＤ的双色亮度进行温度场计算的方法，并进行了误差分析。对试验炉的计算结果表明，此方法具有较高精度，可以运用于火焰的温度场计算和燃烧诊断。
Abstract Flame images obtained with coloured CCD contain the brightness values of the there colours red, green and blue. With the help of experiments and theoretical analysis a method for calculating the temperature field has been developed, which does'nt need a reference point but makes use of two colour brighness of coloured CCD. An error analysis has been in addition. Calculation results of an experimantal furnace shows that this method may claim a relative high precision and may be used for the calculation of temperature fields of flames and also for the diagnosis of combustion.
