线多视图品种

Line Multiview Varieties

Paul Breiding, Felix Rydell, Elima Shehu, Angélica Torres

摘要:

我们提出了一个代数研究针孔摄像机的线对应,在深入研究的点对应。我们将线多视图簇定义为三维空间中的线射影直线映射到二维空间中的像线元组的像的Zapriki闭包。我们证明,在通用相机矩阵的情况下,线多视图品种是一个决定性的品种,我们提供了一个完整的集合理论描述任何相机的安排。我们调查的基本性质,这种多样性,如尺寸,光滑度和多度。最后,我们给出了实验结果的欧氏距离度和鲁棒性下的三角剖分线。

英文摘要:

We present an algebraic study of line correspondences for pinhole cameras, in contrast to the thoroughly studied point correspondences. We define the line multiview variety as the Zariski closure of the image of the map projecting lines in 3-space to tuples of image lines in 2-space. We prove that in the case of generic camera matrices the line multiview variety is a determinantal variety and we provide a complete set-theoretic description for any camera arrangement. We investigate basic properties of this variety such as dimension, smoothness, and multidegree. Finally, we give experimental results for the Euclidean distance degree and robustness under noise for the triangulation of lines.
