摘　　要：传统的空间遥操作人机交互方式是通过鼠标、键盘等进行输入,操作者需要学习繁杂的输入规则,友好性差,缺乏沉浸感。随着我国空间探索任务的发展,很多科学实验通过遥操作的方式进行。用户对空间遥操作系统提出了更高的要求。针对这一问题,文中设计实现了基于手势识别技术的空间遥操作系统。利用微软Kinect摄像机进行手势提取,将手势建模为轨迹,以方向角作为手势特征,实现了模版识别和基于隐马尔可夫模型的识别算法,实现了对常用的六种空间遥操作手势的识别。实验结果表明,基于手势识别技术的空间遥操作系统,设备简单,手势输入准确率高,适合于空间遥操作应用。The traditional human-computer interaction of space tele-operation is via mouse and keyboard. The operators need to learn complex rules for operating,user friendly is poor and the sense of immersion is lacking. With the rapid development of Chinese space ex-ploration missions,many scientific experiments will be done by tele-operation. The user puts forward higher requirements for space tele-operation system. To solve the problem,design and realize the space tele-operation system based on gesture recognition. Make use of the Microsoft Kinect camera for gesture extraction,then moding gesture as trajectory,using direction angle as a gesture feature,realize the template recognition and recognition algorithm based on Hidden Markov model,achieving the recognition of six kinds of commonly used space tele-operation gesture. Experimental results show that the device of space tele-operation is simple and gesture accuracy is high,this system is suitable for space tele-operation applications.
