Structure-from-Motion (SfM) 的 state of art 已开源:colmap/colmap 1、引言 SfM 主要分为了增量式、层次式、全局式。目前,增量式是最为流行的。 2、SfM综述 2.1、关联搜索 由于图像是无序的,所以需要将有重叠关系的图像关联起来,该部分输出为经过几何验证的关联图像集,及地图点对应的图像投影点。主要包含了...

Epipolar-plane image analysis: An approach to determining structure from motion作者:Robert C. Bolles, H. Harlyn Baker, David H. Marimont 摘要 We present a technique for building a three-dimensional description of a static scene from a dense sequence of images. These images are taken in such ...
A novel structure from motion (SfM) pipeline that combines point features and line features together is presented in this paper. Line segments usually are more difficult to handle than points in SfM due to the instability of their end points and the property of being unconstrained by epipolar ...
Structure from motion using line correspondences作者:Minas E. Spetsakis, John (Yiannis) Aloimonos 摘要 A theory is presented for the computation of three-dimensional motion and structure from dynamic imagery, using only line correspondences. The traditional approach of corresponding microfeatures (intere...
