真三维显示相比于二维显示能够提供更直观、更自然的交流模式，近年来受到了国内外的广泛关注。为了实现与真三维显示装置之间自然的入机交互，提出了一套基于美国AetualitySystems公司的Perspceta 3D真三维显示器的人机交互系统。该系统由红外双摄像机跟踪器及手持交互装置构成。跟踪器实时采集交互装置的红外图像并求解装置在真实空间中的三维位置，进而对用户的交互动作进行解析。解析获得的交互数据实时传入计算机并与真三维显示器显示的虚拟物体进行交互，实现了点击、拖动、放大和缩小等自然的交互方式。

For the purpose of direct and natmal display, true three-dimension display has attracted widespread attention from all over the world. To interact with true three-dimension display naturally and directly, a human computer interacting system is developed, which is based on a new prototype truethree-dimension display device named Perspecta 3D display. The system is consist of two infrared cameras and a hand-hold interacting insmmaent. In .frar~ images of the hand-hold instrument are captured ~om the cameras and then the position of the hand-hold instrument in 3D space is calculated in real time by direct linear transformation （DLT） algorithm. Based on the location of the inslrument, the movement of the user is determined by the Kalman filtering method. Then the user can interact with the 3D virtual images in real time, from which commonly
