    • 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 ...

    • Results on an Intrinsic Consensus Algorithm on SO(3) with Almost-Global Convergence 

      Vidal, René; Asfari, Bijan; Tron, Roberto (Department of Electrical and Computer Engineering, Johns Hopkins University, 2012)
      In this paper we propose a discrete time protocol to align the states of a network of agents evolving in the space of rotations SO(3). The starting point of our work is Riemannian consensus, a general and intrinsic extension ...
