摘　　要：针对我国载人航天地面虚拟训练中虚拟手构建的需求,利用Leap Motion手势采集设备,研究了虚拟手构建方法,提出了一种Leap Motion虚拟手模型与约束。采用获取的信息构建出符合人手生理学结构的虚拟手,并通过对比实验、主观评价实验验证了所构建的虚拟手与真实手在完成操作手势时的构型、姿态等的相似性。Leap Motion虚拟手构建方法在设备组装的虚拟操作训练中的应用实践表明:该方法构建出的虚拟手与真实手基本一致,构建速度快,交互性好,能够应用于以虚拟操作为代表的航天员虚拟训练中。Aiming at the requirements of virtual hand construction in astronaut virtual training for manned space missions of China,the virtual hand construction method based on Leap Motion was researched.A Leap Motion virtual hand model and its restrains were proposed.According to the structure of hand,the authors used the acquired information to draw the virtual hand.The structure and gesture of the virtual hand were compared with that of the real one by contrast experiment and subject evaluation.The application of the Leap Motion virtual hands in virtual equipment assembly showed that the virtual hands were constructed fast,with satisfactory interactive feature and were consistent with real hands.It may be used in virtual operation for astronaut virtual training.
