Color selection for a camouflage pattern is a substantial part in designing an effective camouflage pattern. Current color selection methods are often based on the prevailing colors of digital images captured from a scene. However, color extraction from digital images has shown a major difference between the pattern color and the real environment colors. In this article, we present a more precise approach to camouflage color selection based on the spectrophotometric data of dominant objects in a scene. To this end, the dominant objects of a grassland scene were identified. The spectral reflectance of the dominant objects was measured and the percentage of each of them occurred in the scene was estimated. Then, the chromatic values of dominant objects were inserted into an existing camouflage pattern based on the occurrence of each dominant object in the scene. The performance of the obtained colors was assessed by calculating the color difference between the printed camouflage pattern and the dominant objects of the scene. The results showed that using a portable spectrophotometer instead of using a digital camera is more accurate for camouflage color selection and reduces the color difference from the surrounding environment. Furthermore, our method guarantees the absolute similarity between camouflage colors and terrain colors without using camouflage evaluation indexes or photo‐simulation assessment.

使用真实物体的光谱反射率确定最佳迷彩颜色

迷彩图案的颜色选择是设计有效迷彩图案的重要部分。当前的颜色选择方法通常基于从场景捕获的数字图像的主要颜色。但是，从数字图像中提取颜色已显示出图案颜色和实际环境颜色之间的主要差异。在本文中，我们基于场景中主要对象的分光光度数据，提出了一种更精确的伪装颜色选择方法。为此，确定了草原场景的主要对象。测量主要物体的光谱反射率，并估计每个物体在场景中的百分比。然后，根据场景中每个主要对象的出现，将主要对象的色度值插入到现有的迷彩图案中。通过计算打印的迷彩图案和场景的主要对象之间的色差来评估获得的颜色的性能。结果表明，使用便携式分光光度计代替数码相机可以更准确地选择迷彩，并减少与周围环境的色差。此外，我们的方法无需使用伪装评估指标或照片模拟评估，即可确保伪装颜色与地形颜色之间的绝对相似性。通过计算打印的迷彩图案和场景的主要对象之间的色差来评估获得的颜色的性能。结果表明，使用便携式分光光度计代替数码相机可以更准确地选择迷彩，并减少与周围环境的色差。此外，我们的方法无需使用伪装评估指标或照片模拟评估，即可确保伪装颜色与地形颜色之间的绝对相似性。通过计算打印的迷彩图案和场景的主要对象之间的色差来评估获得的颜色的性能。结果表明，使用便携式分光光度计代替数码相机可以更准确地选择迷彩，并减少与周围环境的色差。此外，我们的方法无需使用伪装评估指标或照片模拟评估，即可确保伪装颜色与地形颜色之间的绝对相似性。
