Calibrating Distributed Camera Networks
TL;DR: This paper overviews distributed algorithms for the calibration of such camera networks- that is, the automatic estimation of each camera's position, orientation, and focal length, and shows how a distributed inference algorithm based on belief propagation can refine the initial estimate to be both accurate and globally consistent.
