摘　　要：主要研究在计算机上已经建好的三维模型场景中简单便捷地获取图像对,根据在场景中设置的摄像机对,模拟人眼成像原理,提出获取立体图像对的KFR方法。首先根据针孔模型将图像坐标系中的一点逐步转换到像平面坐标系、摄像机坐标系和世界坐标系,并由坐标轴的二维旋转推导出三维旋转公式,得出影响立体图像显示效果的关键因素的关系式;然后设置摄像机对的排列实现场景的立体显示;最后由显示结果分析得出决定立体效果的关键因素之间的关系。How to simply and conveniently obtain image pairs from the 3D model scene which has been built in computer is mainly studied. By simulating the human eyes imaging principle according to the camera pairs set in the scene,a KFR method for obtaining the stereo image pairs is proposed. According to the pinhole model,a point in the image coordinate system is gradually transformed to the image plane coordinate system,camera coordinate system and world coordinate system. The 3D rotation formula is derived from the 2D rotation of the coordinate axes,so as to obtain the relational formula of key factors that affect the display effect of stereo images. The arrangement of camera pairs is set to realize the stereo display of the scene. The display results are analyzed to obtain the relationship between key factors that determine the stereo effect.
