Study on Pigment Compounding and Spectral Mixing Models for Simulating Green Vegetation
The design of camouflage materials simulating green vegetation needs to meet the requirements of"same color"and"same spectrum"as the background.In this article,green camouflage pigment with water absorption peaks were prepared by mixing inorganic pigments iron oxide yellow and chromium green to eliminate the blue peaks,and further blending with hydrotalcite.The obtained green camouflage pigments were compared with green plants,with a maximum spectral similarity of 93.95%.And a spectral unmixing model was established to analyze camouflage pigments.The analysis results indicated that the mixed pigments of chromium green/iron yellow and hydrotalcite exhibit strong nonlinearity overall and strong linear mixing characteristics in certain specific wavelength ranges.
