Structure from Motion Using Structure-Less Resection

Enliang Zheng, Changchang Wu
2015 2015 IEEE International Conference on Computer Vision (ICCV)  
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.  ...  Acknowledgment We thank Henrik Stewénius for sharing the Macaulay2 code of their paper [17] .  ...

Fast Structure from Motion for Sequential and Wide Area Motion Imagery

Hadi AliAkbarpour, Kannappan Palaniappan, Guna Seetharaman
2015 2015 IEEE International Conference on Computer Vision Workshop (ICCVW)  
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.  ...  The views and conclusions contained in this document are those of the authors and should not be interpreted as representing the official policies, either expressed or implied, of AFRL, NRL, or the U.S.  ...

On Linear Structure from Motion for Light Field Cameras

Ole Johannsen, Antonin Sulc, Bastian Goldluecke
2015 2015 IEEE International Conference on Computer Vision (ICCV)  
From the relationships between scene geometry and light field structure and an analysis of the light field projection in terms of Plücker ray coordinates, we deduce a set of linear constraints on ray space  ...  These can be applied to infer relative pose of the light field cameras and thus obtain a point cloud reconstruction of the scene.  ...  Strategies for structure-from-motion.  ...

Ji Zhang, Mireille Boutin, Daniel G. Aliaga
2011 IEEE Transactions on Image Processing  
Structure from motion (SFM) is the problem of recovering the geometry of a scene from a stream of images taken from unknown viewpoints.  ...  First, we take the standard SFM equations in projective coordinates and eliminate the camera orientations from the equations. We then further eliminate the camera center positions.  ...  In particular, it was shown in [8] that the two most popular classes of 3D motion estimation algorithms (those optimizing the epipolar constraint from point correspondence and those minimizing the negative  ...

We describe a pipeline for structure-from-motion (SfM) with mixed camera types, namely omnidirectional and perspective cameras.  ...  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.  ...  After a few remaining false matches are eliminated by employing RANSAC 660 on the hybrid epipolar constraint, we obtain a reliable set for motion estimation.  ...
