摘要 为了增强三维场景视点控制的自然性,给用户更多的交互沉浸感,设计并实现了一套自然的三维场景视点控制系统.系统采用立体视觉方法定位用户头部的三维空间运动,并利用计算机图形学原理将头部运动映射为三维场景的视点控制.同时,为了方便用户锁定当前视点,系统采用语音识别方法实现基于头部运动的视点控制方式的启动和关闭.测试实验结果表明,该系统是可行的、实用的. In this paper,a novel natural 3D viewpoint control system designed and implemented to enhance the naturalness of the viewpoint control and to give users more immersion perception is presented.In our proposed approach,the user's head position is obtained in 3D space by employing stereo vision methods.Then the head motion is mapped as viewpoint changes.Moreover,viewpoint locking via user voice is supported through voice recognition.Our experiments demonstrate that the proposed system is effective in practices.
