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 ...
In this chapter, we look at the converse problem of estimating the locations of 3D points from multiple images given only a sparse set of correspondences between image features. While this process often involves simultaneously estimating both 3D geometry (structure) and camera pose (motion), it ...

Structure from Motion(SfM)（从运动图像中恢复三维结构），是⼀种从可能带有本地运动信号结合的⼆维图像序列中预测三维结构的摄影测量序列图像技术。它在计算机视觉和视觉认知领域有研究。在⽣物视觉中，StM指的是⼈（或者其他活着的⽣物）可以从⼀个运动物体或场景的投影的⼆维运动领域恢复三维结构的现象...

observed. Our conjecture from this work is that the imposition of the constraints arising from projective geometry should be used as an intermediate step in order to obtain reliable 3D Euclidean motion and structure estimation from multiple calibrated images. The software is available from the ...
