电子上妆技术在载人航天中的应用设计

Application and design of electronic makeup technology in manned spaceflight

针对空间站为代表的空间活动驻留宇航员上镜时的妆容美化需求和空间环境资源限制等问题,通过图像处理的方法为宇航员进行虚拟上妆,优化航天员个人形象。对妆容迁移技术现状和载人航天中的问题进行了初步的探索和讨论,进一步提出虚拟上妆的优化设想,设计了基于生成对抗网络的妆容迁移模型。通过该模型可以对宇航员图像或视频的关键帧进行自动美颜,实现宇航员面部的虚拟上妆。实验结果表明,在不会改变宇航员的身份信息的基础上,通过优化后的循环一致性生成对抗网络对宇航员图像面部、眼部及唇部都可以进行迁移上妆,且不需要额外的手动交互。电子上妆技术解决了太空中宇航员个人形象维护难的问题,对进一步提升航天员形象有一定的参考价值。

Given the astronauts’ need for makeup and beautification in space activities represented by the space station and the limitation of space environment and resources, the image processing method is used to perform virtual makeup on astronauts in order to optimize the personal image of astronauts. The current situations of makeup transfer technology and the problems in manned spaceflight are explored and discussed preliminarily, optimized ideas of virtual makeup is then proposed, and a makeup transfer model based on generative adversarial network is designed. Through this model, the key frames of astronauts’ images or videos can be automatically beautified to realize virtual makeup for astronauts. The experiment results show that on the basis of not changing the identity information of astronauts, the faces, eyes and lips of astronauts’ images can be migrated and applied through the optimized cycle-consistent generative adversarial network with no additional makeup and manual interaction needed. The electronic makeup technology solves the difficult problem of maintaining personal images of astronauts in space, and is of important reference value to further image improvement of China’s manned spaceflight.
