Visual Servoing from Spheres using a Spherical Projection Model
— In this paper, we investigate the use of a spherical projection model to search for optimal visual features for visual servoing. A new minimal set of three visual features is p...

Dissecting the Image of the Absolute Conic
In this paper, we revisit the role of the image of the absolute conic (IAC) in recovering the camera geometry. We derive new constraints on IAC that advance our understanding of i...

Camera Calibration from the Quasi-affine Invariance of Two Parallel Circles
Abstract. In this paper, a new camera calibration algorithm is proposed, which is from the quasi-affine invariance of two parallel circles. Two parallel circles here mean two circl...

Multiple Camera Calibration with Bundled Optimization using Silhouette Geometry Constraints
We propose a method of calibrating multiple camera systems that operates by adjusting the camera parameters and the 3D shape of objects onto silhouette observations. Our method em...

Projection Model, 3D Reconstruction and 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 light ray direction from the image...
