Camouflage effect evaluation based on hyperspectral detecting technology

Camouflage is an important factor for winning the modern warfare by preserving fighting capacity. Hyperspectral imaging technology is an efficient method for camouflage detection for its ability of detecting and utilizing targets' spectral information. Traditional camouflage effect evaluation method mainly based on spatial characteristics, which cannot work when hyperspectral imaging technology is used. So a new camouflage effect evaluation method was proposed for hyperspectral detection, which was based on the comprehensive similarity of camouflage and background combined characters of spectrum and its derivative. Target with higher comprehensive similarity meant better camouflage effect. Experiment was conducted to assess the camouflage effects of three camouflage materials by the new method. The camouflage effect of green cloth outperforms others with the comprehensive similarity 0.976 6. And error rate based on hyperspectral classification technology was proposed to verify the objectivity of the new method. The new camouflage effect evaluation method has a certain guiding significance for the design of the new camouflage material.
