| 摘 要： | 为了提高基于CCD图像测温的准确性,针对波长的选取对温度计算结果产生的较大影响,提出了一种不依赖于CCD光谱特性及其三基色代表性波长的改进比色测温方法.利用三基色中两两基色与温度的关系得到三个温度解,最后利用三个温度解之间的相关性进行优化,得出最优温度解.改进方法不仅避免了由于选取波长带来的测温误差,而且得到的计算值更...

| Abstract: | To improve the accuracy of temperature measurement using CCD image,for the selection of the wavelength impacts the result of the temperature measurement greatly,an improved colorimetric temperature measurement method is proposed,which is independent of the spectroscopic characteristics and the representative wavelengths of the CCD.Using the relationship between color and temperature,three solutions of temperature are obtained,and the temperature value based on the correlation of those temperatures is optimi... |
