由单镜头图像序列确定刚体的三维结构及运动参数是计算机视觉领域中最为基大的问题之一本文对这一问题进行了讨论,提出了一种利用刚体上直线在帧间的变化,估计刚体的可视部分结构及其三维运动参数的新方法。在该方法中,仅用到刚体上三条互不平行的直线在两帧中的对应关系因此,与文献中的方法相比,本文中的方法更为简单。 Determining the three-dimensional structure and motion parameters of a rigid body from a single-lens image sequence is one of the most fundamental problems in the field of computer vision. This paper discusses this issue and proposes a method to estimate the rigid body The visual part of the structure and its three-dimensional motion parameters of the new method. In this method, only the correspondence between two non-parallel lines in the rigid body is used in two frames. Therefore, the method in this article is simpler than the method in the literature.
