对测温系统中的光学模型进行讨论确定了像点与物空间的对应关系;结合CCD工作原理和光学系统光辐射度的分析,建立了CCD产生的信号和物体表面辐射量的关系式;对彩色CCD比色法测温的误差进行了计算比较,得出了由红色和蓝色亮度计算温度场的结论。
The optical model of the temperature measurement system is discussed to determine the correspondence between the image point and the object space. According to the working principle of the CCD and the optical radiance of the optical system, the relationship between the signal generated by the CCD and the surface radiation is established. Color CCD colorimetric error of the temperature calculation and comparison, obtained by the red and blue brightness temperature field conclusion.
