基于多光谱和sRGB空间的自然植物色的重现

多光谱成像技术在颜色科学方面的应用主要在于准确的记录和复制拍摄场景的颜色信息。针对目前基于光谱的颜色重现设备昂贵、复杂和实现起来困难的问题,提出了物体颜色从反射光谱空间向sRGB颜色空间变换的方案。在遵循sRGB标准的设备上重现了D65光源下的218种自然植物颜色,所显示的颜色与植物反射光谱实物对应的名称一致。对8个自然植物在9种不同光源下和在sRGB空间下的颜色进行了预测显示。所提出的方案对在网络环境下实现相同实物在不同照明环境下的场景显示提供了可行的途径。

Natural plant color reproduction via sRGB base on multispectral space

The application of Multispectral imaging in color science is to acquire the spectral information of the imaging scene,and consequently high fidelity color reproduction can be achieved.A method of color reproduction based on multispectral is proposed,which transforms information of object color from multispectral space to sRGB color space.The 218 colors of corresponding natural plant appearance spectrums are dispayed in sRGB space under D65 illuminate,and the reproduce color are the same as the nature plant names.The colors' prediction results of 8 natural plant spectrums under 9 different light source are shown.The method provides a feasible way of realize displaying a object appearance under different illuminants.
