摘　　要：研究了由带有视差的图像对恢复摄像机矩阵和空间物体的三维几何形状这一多视图三维重构问题,结合Hartley和Rorther等人提出的基于无穷远平面诱导的单应进行射影重构算法,提出了根据图像间的对应关系确定插补图像像素的位置和灰度的新算法,通过这种新算法输出符合双眼特性的体视图像,试验证明插补后体视图像效果较好,速度快。This paper investigates the problem of how to carry out 3D projective reconstruction from multiple images, it is commonly accepted that the bundle adjustment and factorization method are the main methods for projective reconstruction. But the bundle adjustment needs a good initialization and extremely expensive computation,and the factorization method is limited by the restriction that all 3D points must be visible in all views recently, a linear algorithm of projective reconstruction based on the homography induced by the infinite plane was given by Hartley and Rother et al. This paper improves their algorithms and proposes a new image interlaced algorithm according to the corresponding relationship between the images. The algorithms are evaluated on both synthetic and realworld images, and the experiment results show the method is accurate and only affected slightly by noise.
