增强现实技术在载人航天工程中的潜在应用

摘要

增强现实是近年来的研究热点，它的三大支撑技术分别为跟踪注册技术、显示技术和交互技术。增强现实可以将计算机产生的虚拟物体叠加融合于真实场景之中，具有虚实融合、实时交互和辅助增强等特点。在我国载人航天工程的许多实践中，诸如太空维修和大时延遥操作等，增强现实技术可以发挥独特的作用。回顾了增强现实的三大支撑技术，展望了增强现实在载人航天工程中的潜在应用，分析了其中的技术难点，并提出了相应的方案。%Augmented Reality （AR） is a relatively new and highly interdisciplinary field of research, which can fuse the real world with virtual （computer-generated） objects that appear to coexist in the same space as the real scenes. With the characteristics of virtual-reahty and real-time interaction, AR technology is suitable for some of the potential applications in China manned space engineering, such as space maintenance and teleoperation with large time delay. The three major enabling techniques of AR, namely tracking, display and interaction, are introduced, the potential applications of AR in manned space engineering are proposed, and the relevant technological challenges are discussed.
