基于辐射特性的物体色度值计算机模拟表征

Computer simulation of color characterization based on the radiative properties of objects

不论是在植被仿真或者遥感图像解译中,颜色都是极其重要的一个因素。如何能真实再现地物的颜色并使其具有一定的辐射意义呢?本文基于地物的辐射特性,以国际标准CIE(国际照明委员会)所规定的XYZ空间体系为基础,通过ASD测量出待实验地物的反射光谱,结合计算机计算的方法,以此计算出准确的颜色RGB值,并可直接在计算机屏幕上将颜色表达出来。结果表明:实验结果和理论分析的符合是相当好的。

No matter in vegetable simulation or in RS image interpretation,the colors are extremely an important factor.How can we reproduce the true color of features and make it process a certain significance of radiation?Based on the XYZ space-based system of CIE(the Commision Internationale De Eclairage)and reflection spectrum measured by the ASD ,combined with computer-based methods in order to accurately calculate the RGB color value,we can display the color computer screen directly.The results showed that:the experimental results and theoretical analysis matches quite well.
