【摘要】 增强现实技术是一种将真实世界信息和虚拟世界信息"无缝"集成的新技术,将增强现实技术应用于设计系统,需要加强交互功能以支持用户修改操作.结合基于视觉计算的增强现实系统的关键技术,将需要为用户提供的交互操作功能归纳为与现实世界交互、与虚拟物体交互以及与历史交互三个方面,并探讨了利用虚实合成相关参数来存储和调出实景中虚实合成效果的方法.通过实例运行,表明了交互式增强现实技术能比基于标记的增强现实系统更为方便、有力地支持用户的设计构思,有助于将增强现实技术应用于室内装饰和景观设计等领域.更多还原

【Abstract】 Augmented Reality(AR) is a new technique which seamlessly integrates information of real world and virtual world.While AR is applied to system design,interactive functions have to be enhanced so as to support the modification operations of users.By integrating key techniques of AR system based on vision computation,the interactive operation functions provided to users were induced into three aspects including interaction with real world,interaction with virtual world and interaction with history.The methods of loading and storing real-virtual synthesis effects by relative parameters were discussed and explored.Experiment shows that the new augmented reality interactive technique is more convenient and powerful than the sign based AR system in supporting the design idea of users,and suitable for application in such fields as indoor decoration and landscape design.更多还原
