The technological development of computer vision provides a new path for improving camouflage effects. As an important means of anti-reconnaissance, camouflage plays an important role in competing for information superiority. In an effort to ameliorate the camouflage effect of camouflage net based on computer vision, a method of using decorative pieces on the camouflage net was proposed, and the color determination and fixation methods of decorative pieces were studied. Taking forest type camouflage net as an example, this article compared the similarity of edge and color distribution before and after adding decorative pieces for experiments; Through comprehensive analysis of cost-effectiveness and universality, this article determined the color types and specific color information of the decorative piece production; This study determined the usage of decorative pieces and camouflage net through the average time of repeated experiments. On the basis of the above experiments and analysis, the color variety, layout, shape and size of highly fused decorative pieces on the camouflage net were determined, which provides a brand-new method for improving the camouflage effect of camouflage net based on computer vision.
