Distributed Image-Based 3-D Localization of Camera Sensor Networks

Tron, Roberto; Vidal, René (Department of Electrical and Computer Engineering, Johns Hopkins University, 2009)

We consider the problem of distributed estimation of the poses of N cameras in a camera sensor network using image measurements only. The relative rotation and translation (up to a scale factor) between pairs of neighboring ...

Automatic Calibration of Cameras with Special Motions

Vidal, René; Elhamifar, Ehsan (Department of Electrical and Computer Engineering, Johns Hopkins University, 2009)

We consider the problem of auto-calibrating the intrinsic parameters of a camera moving with a special motion: the rotation axis of the camera being perpendicular to its translation direction. Our method for calibrating ...
