摘要
基于新型的多维成像技术,研制了一种基于液晶可调滤光器(Liquid Crystal Tunal Filter,LCTF)的多光谱图像色彩复制装置,实现了对图像色彩信号的复制,将多光谱成像技术应用于色彩复制领域。描述了系统的工作原理、装置的详细设计与实现过程等,通过该装置对计量院校准过的标准色卡复制成像,获取了31个通道多光谱图像,色差ΔE_(Lab)=2.7,合成后的彩色图像质量良好,色差小、复制精度高,可用于多个领域图像色彩的精确复制和可视化逼真再现。
Based on the new type of multi-dimensional imaging technology, a kind of device based on LCTF multi-spec- tral image color reproduction is developed. The image color signal replication is realized, and the multi-spectral imaging technology is applied to the field of color reproduction. The working principle of the system, the detailed design and im- plementation process are described in this paper. The standard color card is copied and imaged through the device. The 31 channels multi-spectral images are obtained with △E Lab =2. 7. The synthesis of color image quality is good, the color difference is small, and the copy precision is high. It can be used for precise copy and visual reproduction of image color in many fields.
