基于两幅图像的三维物体分层重构

3D Stratified Reconstruction from a Pair of Images

文章研究在仅有两幅图像的条件下,如果摄像机内参数保持不变,如何利用场景中的结构信息实现空间物体的分层重构,研究表明,计算出无穷远平面的单应矩阵,可以仿射重构,计算出绝对二次曲线的像,就可以进一步实现欧氏重构。最后给出一个具体的实验,结果表明该算法是可行的。

This paper discusses if two cameras have the same calibration matrix how to use some knowledge of scene's to stratify reconstruction from a pair of views .The essence of affine reconstruction is to compute the infinite homography.The key to metric reconstruction is identification of the abso lute conic image.In the end,it gives a experiment ,and the re sults indicate that it is efficient.
