摘　　要：3D摄像系统的内参数以及相互位置关系与视差、立体深度密切相关。在双镜头3D摄像系统数学模型的基础上设计了组合式3D摄像系统,提出了一种基于显像棋盘作为标定靶面的新方法,直接利用液晶显示器生成动态标定靶面,运用标定工具箱对双摄像头内外参数进行标定,并利用标定的参数验证组合式3D摄像系统结构设计的合理性。实验表明,该标定方法方便、快捷,操作过程简单,取得了较高的精度,适合3D摄像系统的标定,标定后的组合式3D摄像系统符合人眼立体视觉。Stereo depth and parallax are closely related with the intrinsic parameters and the relation of mutual positions in 3D camera system. In this paper,the combined 3D camera system is designed on the base of the mathematical model of double lens 3D camera system and a new method of stereo calibration based on the imaging chessboard is proposed. It directly adopts LCD monitor to produce dynamic calibration target. Intrinsic and external pa- rameters are calculated with calibration toolbox ,and parameters are used to prove the rationality of the design of combined 3D camera system structure. The experimental results show that this calibration method not only acquires high precision ,but also its process is convenient and fast, and can be applied to 3D camera system. The combined 3D camera system after calibration is in line with the human eye stereo vision.
