固定目标伪装的数码迷彩设计

传统迷彩的边缘平滑、色彩分明、视觉区分度强,其设计过程往往脱离伪装目标的实际背景,不能很好地与背景相融合。数码迷彩在图案上呈现不规则的重叠,不同颜色间的边缘模糊、破碎,极易模拟自然背景。文章提出一种根据目标的背景生成数码迷彩的新方法。根据实际需求确定数码单元的尺寸,然后采用模板遍历的方法对背景图像中的主要颜色进行重新排布,最后生成数码迷彩。利用此算法生成的数码迷彩能够较好地保留背景的细节特征,并与目标的自然背景高度融合,从而达到良好的变形和光学伪装效果。

Design on Digital Disruptive Pattern for Fixed Targets

The traditional camouflage is based on a number of irregular spots or stripes,whose edges are smooth as well as they have clear boundaries between different colors.The visual distinction degree is so strong that the camouflage effect is debased.The digital disruptive pattern can break the boundary of a camouflaged target between different colors,as well as makes it blurred and broken,so as to attain a better camouflaged effect.This paper presents an algorithm which can generate digital disruptive pattern according to background images of the target.It uses a square template to traverse the background image as to rearrange the dominant colors of it,followed that determines the size of a mosaic block.Finally the digital disruptive pattern is generated.The experimental result shows that,the generated pattern is easier to blend with the natural background than the traditional camouflage,and achieves a good effect of the optical camouflage.
