| 摘 要： | 推导出具有实物面的高温辐射体温度和CCD像素点亮度之间的关系。结合比色测温法，给出一种基于彩色CCD图像的温度场测量方法。用一套经黑体炉标定过的测温系统，分别在黑体炉和普通煤炉上进行测温试验，取得较好结果。通过比较计算温度值和热电偶测量值，分析了本测温方法的误差来源。

| 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 of the method are compared with the results of thermocouple,and it shows that the precision of the method is satisfying.Furthermore,the measurement errors are analyzed. |
