This paper proposes a new incremental structure from motion (SfM) algorithm based on a novel structure-less camera resection technique. ...
By integrating these new algorithms in an incremental SfM system, we go beyond the state-of-art methods with the capability of reconstructing cameras without 2D-3D correspondences. ...

We present a fast and efficient Structure-from-Motion (SfM) pipeline for refinement of camera parameters and 3D scene reconstruction given initial noisy camera metadata measurements. ...
Since the sequential ordering of the cameras is known, consecutive frame-to-frame matching is used to find a set of feature correspondences for the triangulation step of SfM. ...

Following the addition of multiple perspective and omnidirectional images to the structure, we perform sparse bundle adjustment on the estimated structure by adapting it to use the sphere camera model. ...
