摘要
研究了由多幅图像恢复摄像机矩阵和空间物体三维几何形状的问题,对Cross等人提出的利用无穷远平面诱导的单应进行重构的算法进行了改进,提出了一种新的算法。该算法只需要一个点和一条直线在所有视图中均可见,解决了原算法要求4个共面参考点的难题。
This paper investigates the problem of how to carry out 3D projective reconstruction from multiple images. Recently,a linear algorithm of multi view reconstruction based on the homography induced by the infinite plane was given by Cross et al.In this paper,a new algorithm is given.h is shown that only one point and one line have to be visible in all views,so resolves the difficulty of the former algorithm which requires four coplanar reference points.
