| 摘 要： | 研究了基于选择最优滤光片多光谱成像系统优化问题,采用了优化的滤光片组合,组建了一个六通道的多光谱成像系统。利用提出的基向量和多项式组合的方式重构光谱数据,成功重建出博物馆、美术馆等展览馆常用的两种典型光源模拟器D65和A光源下油画的光谱反射率,并以光谱均方误差和色差综合误差评价成像质量。对两种光源下重建结果分析可得,最优滤光片的选取与光照环境密切相关。根据光照环境不同采用选取出的最优滤光片可得到最好光谱成像图,并且能在光谱和色度上都达到较高精度。

| Abstract: | The problem of selecting an optimized filter of multi-spectral imaging system is studied.We used the optimized filter combination to form a six-channel multi-spectral imaging system.The spectral reflectance of two kinds of light sources that are commonly used in the museums,art galleries and other exhibitions is reconstructed successfully by using the method of base vector and polynomial combination.The imaging quality is evaluated by using the mean square error and color difference.For the reconstruction results of the two kinds of light sources,the selection of the optimized filter is closely related to the light environment.According to the different light environment,the best spectral image map is obtained by the best spectral imaging,which can achieve higher accuracy in the spectrum and chromaticity. |
