Projection Model, 3D Reconstruction and Rigid Motion Estimation from Non-Central Catadioptric Images
13 years 11 months ago
This paper addresses the problem of rigid motion estimation and 3D reconstruction in vision systems where it is possible to recover the incident light ray direction from the image...
