摘　　要：以未来空间站任务建设虚拟现实训练器为需求,为了最大限度地降低虚拟现实设备穿戴给航天员带来的额外束缚,提出了一种新的基于体态识别的航天员虚拟训练仿真系统:采用平行双目视觉原理和偏振立体电视实现立体图像的生成与显示;采用人体三层模型实现虚拟航天员表达,采用骨骼动画实现人体典型动作自动演示、Kinect实现人机交互过程中人体跟踪和运动控制,适合于空间站任务航天员训练、工效验证、典型流程演示等人机交互应用。Virtual training simulation,as a kind of full digital simulation,can create some special situation that physical or half hardware device is difficult to make.To meet the requirements of astronaut virtual reality trainer in the future space station mission,which can minimize the extra constraint feelings from the traditional virtual reality hardware device,a new astronaut virtual training simulation system based on posture recognition was proposed.It uses the parallel binocular vision principle to generate three-dimensional（3D） stereo image,which can be displayed on polarized 3D stereo TV.The three layers model of human body was adopted to express virtual astronaut,and skeletal animation was used to demo typical human body movement.The Kinect device was applied to track real astronaut body motion to control virtual astronaut body movement.The system is natural during human-computer interaction,which avoided the shackles of wearable virtual reality device for human body moving.It can be applied to astronaut training,ergonomics validation,and typical operation process demonstration in the future mission,etc.
