中文摘要： 增强现实是借助三维显示技术、交互技术、多种传感技术等把虚拟信息融合到真实环境的技术，强调虚拟对象与真实环境的融合与交互，并以此增强人对真实环境的认知能力。增强现实环境下，徒手操作虚拟物体为数字化装配提供了更自然的交互操作方式。手、虚拟零部件和真实环境构成了增强现实装配操作空间。在这样一种操作空间中，如何感知虚拟物体和真实物体的空间位置、相互关系是实现徒手操作虚拟物体的关键。本项目的科学问题是自然手势操作虚拟物体的智能感知，旨在突破虚实融合、深度信息感知，徒手操作虚拟物体的交互技术等方面的难题，促进具有自然交互特征的数字化装配技术的发展。项目具体研究内容包括：基于视觉的真实对象深度信息恢复方法；虚拟物体和实际场景的融合理论；基于计算机视觉的自然手势交互和装配语义模型。本项目预期在理论研究方面取得重要进展，获得发明专利，并开发出基于增强现实环境的徒手装配数字化系统，应用于复杂产品的装配和维护。

英文摘要： Augmented reality (AR) technology integrates the virtual object to the real world with the help of 3D display technology, interactive technology, a variety of sensor technologies. It emphasizes the interaction and confusion of the virtual 3D models and the real world. AR technology can enhance a user's perception of the real world with information that is not actually part of the scene but is relevant to the user's present activity. To manipulate virtual 3D models by hands in augmented reality environment supports a free interactive manipulation for digital assembly. In this case, hands, virtual models and real objects component an augmented reality assembly space. How to percept the configuration relationship between the virtual models and real objects in the augmented reality assembly space is the key problem for capturing virtual models by hands. The science problem addressed in our proposal is intelligence perception of the interaction with virtual models by natural hands gesture. The objective of our proposal is to give a solution to confusion between virtual and real world, depth information modeling and interaction technologies with virtual models by free hands. This can support the improvement on digital assembly technology featured with natural interaction by hands. The studied issues addressed in our p
