摘要
针对具有纹理特征的土家织锦表面颜色复制,选用标准灯箱作为多光谱获取系统的光源环境以降低纹理特征的影响,配以短波段窄带滤色片来增强蓝紫光波段的光谱信息,进行多光谱反射率信息重建来获得高保真的土家织锦颜色复制.重建实验结果评价显示,待测样本的适应度系数GFC的平均值为99.63%;RMSE的平均值为2.52%;重建结果的色差ΔE_（ab）＊的平均值为1.93个色差.可见所采用的多光谱获取系统和光谱估计算法针对有纹理特征的土家织锦颜色的光谱反射率信息的重建具有可行性,能得到满意的结果.
Reconstruction of spectral information of Tujia brocade with texture features was achieved by multi-spectral technology.The standard light booth and short wave narrow-band filters were used in multi-spectral acquisition system to reduce the effect of texture feature and enhance the spectral information in the blue violet band respectively. In the evaluation of the results of the reconstructed testing sample results,the average of GFC is 99.63%; the average of RMSE is 2.52%; the average of ΔE_（ab）~＊ is 1.93. It can be seen from the results of the reconstruction that the algorithm and the system is available for reconstruction of Tujia brocade with texture features.
