| 摘要: |
| 为更好地模拟变色龙的皮肤,提出一种使用微流控变色系统模拟变色龙皮肤的伪装薄膜的方法。通过感知和采集环境背景颜色信息,实时调节微流控变色系统的变色信号,驱动有色液体在伪装薄膜的微流道内循环,实现动态隐身和伪装。介绍薄膜的微观结构和微流控变色系统的工作原理,阐述通过深度学习图像补全算法及图像处理技术产生变色信号的方法,采用“Canny”双阈值边缘检测算法和颜色相似度对伪装效果进行分析和评价。实验结果表明:伪装后的变色龙皮肤的边界轮廓不明显,与环境背景具有较高的相融性,可以达到动态隐身效果。微流控变色系统伪装薄膜可应用于官兵迷彩服、机器人皮肤、武器装备和军工设施的伪装网等多种场合。 |

| Abstract: |
| To imitate the chameleon skin, a method using microfluidic color-changing system to camouflage films is proposed. By sensing and collecting environmental color change information, the control signal of the microfluidic system can be adjusted in real-time to drive the dyed liquids circulating in the micro channels of the camouflage film to achieve dynamic cloaking and camouflage. The microstructure of the film and the working principle of the microfluidic color-changing system are introduced. The mechanism to generate the color signal by deep learning image completion algorithm and image processing technology is illustrated. “Canny” double-threshold edge detection algorithm and color similarity are used to analyze and evaluate the camouflage. The tested results show that the camouflaged chameleon skin is not obvious and has a relatively high compatibility with environmental backgrounds and the dynamic cloaking effect can be achieved. The camouflage film implemented by the microfluidic color-changing system can be applied to various occasions such as camouflage uniforms for officers and soldiers, robot skins, weapon equipment, and camouflage nets for military facilities. |
