摘要
开发了一种虚拟场景与实时视频之间的合成技术,提出了一种新的基于非定标技术的虚实配准方法,有效地解决了基于标识的三维注册系统要求摄像机内参在系统运行过程中不能发生改变的限制。详细介绍了系统所采用的基于计算机视觉的标识识别和实时自动摄像机位置、姿态跟踪算法,并给出了系统运行结果,成功地将该技术应用于虚拟规划系统中。
Aimed to solve the restrict of keeping the intrinsic parameters of a camera constant which is required by 3D registration system based on market recognition, the virtual-real synthesis technology that integrate virtual sense and real-time video is presented and cali- bration-flee registration method is proposed. The market recognition method based on computer vision and tracking algorithm about the position and orientation of a camera are presented in detail. A novel system is proposed to validate the feasibility of using AR （augmented reality） in residential area planning.
