摘要：

推导出了CCD像素点亮度和具有实物面的高温辐射体温度之间的关系。结合比色测温法，提出了一种基于面阵CCD图像的温度场检测方法。分别在普通煤炉和黑体炉上用一套经黑体炉标定过的测温系统进行测温实验，取得良好效果。通过比较热电偶测量值和本算法计算温度值,分析了本测温方法的误差产生原因。

Abstract:

The formula between temperature of the objects having real surface and luminance of the pixels in the CCD image is deduced. A high temperature field measurement method based on color CCD is discussed according to the principle of two-color pyrometer. The method is used to measure the temperature of a black-body furnace and a coal furnace through a CCD camera, which is scaled by a black-body furnace beforehand. The calculation data is compared with the measurement results of thermocouple, and it shows that the precision of the method is satisfying. Furthermore, the measurement errors are analyzed.

Key words: two-color pyrometering, CCD image, temperature field, infrared radiation
