雪地背景伪装研究对于伪装设计与伪装识别均具有重要的意义。本文研究了高白度、高反射率的雪地型伪装材料的性能检测技术。针对冬季雪地背景和典型目标样品(白纸、白棉布和白色伪装材料), 开展基于光谱曲线间相似性、基于紫外图像直方图和灰度平均对比度相似性的伪装检测技术研究。通过光谱反射因数的欧氏距离和光谱角余弦计算伪装样品与雪地背景的相似性, 通过平均灰度值对比和直方图的归一化相关系数巴氏距离来判断伪装目标和雪地背景的相似程度, 证明了反射光谱和紫外图像检测的可行性和有效性。研究结果对雪地型伪装装备的研制和设计定型试验有一定的指导意义。

The study on the background of snow is very important for camouflage design and camouflage identification. This paper studies the performance testing technology of snow camouflage material with high whiteness and high reflectivity. According to the winter snow background and typical samples (white paper, white cotton and white camouflage materials), to carry out research on camouflage testing technology of spectral similarity between spectral curve, image histogram similarity and the gray average contrast. The method is calculating the similarity of the samples and the snow background through Euclidean distance and Spectral angle cosine of the spectrum reflectance factor; judging the similarity between the camouflage object and the snow background by the average gray contrast and histogram normalized correlation coefficient Bhattacharyya distance. The feasibility and effectiveness of the reflection spectrum and the UV image detection are proved. The results of the study has some guiding significance for the development and Design Finalizing Test of the snow camouflage equipment.
