双色与三色比色测温是彩色CCD辐射测温常用方法。通过理论分析和实验研究，分别从测温动态范围和测温精度两方面对双色法和三色法进行了比较研究。研究发现，在光圈快门组合保持不变的条件下，选取红、绿双色进行比色测温具有较宽的测温动态范围；在对辐射体做灰体假设的情况下，三色测温方法具有更高的测温精度。提出了构建一种可切换测温方法的统一测温硬件平台，统一测温平台综合了双色法和三色法两者的优点，可同时满足更宽的测温动态范围和更高的测温精度的要求，应用灵活。

The two-color and three-color colorimetric temperature measurements are major methods of the colored CCD-based radiation thermometry. The dynamic range and temperature measurement accuracy of the two-color and three-color thermometry are analyzed and compared respectively. The theory analysis and experimental results show that the two-color thermometry using red-green colors has much wider dynamic range than the three-color thermome?try in the combination of an aperture and shutter. In the other hand,the three-color thermometry has higher accura?cy than the two-color method when the radiator is assumed as a gray-body. Finally,the general temperature measure?ment platform flexibly switching the two-color and the three-color thermometry is proposed. The measurement plat?form combines the advantages of the two-color and three-color thermometry,which meets the requirements of wide dynamic range and high measurement accuracy.
