无对应点匹配的三维重建

3-D Reconstruction Using Correspondenceless Stereo

本文首先纠正了基于二次曲线匹配视觉算法中所存在的推导错误，并对于重建曲线解的存在性进行了讨论，给出了一种能保证解存在的修改算法。其次，为了保证解的唯一性，我们给出了采用三眼视觉的唯一性匹配定理，最后采用机械零件进行了实验，证明所提出的方法可以快速、准确、完整地重建空间曲线。

In this paper, first some errors in derivation of the correspondenceless approach of quadric curve based stereo are corrected; and its existence of the solution for the reconstruction of curve are addressed. Subsequently in order to determine a unique solution, we propose a unique matching theorem using a trinocular vision setup. Finally some experiments with scenes of mechanical parts are described. It is demonstrated that planar curve objects can be reconstructed completely, correctly and quickly by using our approach.
