Camera Calibration with Two Arbitrary Coplanar Circles
Abstract. In this paper, we describe a novel camera calibration method to estimate the extrinsic parameters and the focal length of a camera by using only one single image of two c...

Affine Epipolar Direction from Two Views of a Planar Contour
Most approaches to camera motion estimation from image sequences require matching the projections of at least 4 non-coplanar points in the scene. The case of points lying on a plan...

Rigid Motion Estimation from Non-Central Catadioptric Images
This paper addresses the problem of rigid motion estimation and 3D reconstruction in vision systems where it is possible to recover the incident direction from image points. Such ...
