As the prices of cameras and computing elements continue to fall, it has become increasingly attractive to consider the deployment of smart camera networks. Such camera networks could be used to support a wide variety of applications
including environmental modeling, 3D model construction and surveillance.[3, 2, 7, 4] One critical problem that must be addressed before such systems can be realized is the issue of localization. That is,in order to take full advantage of the images gathered from multiple vantage points it is helpful to know how the cameras in the scene are positioned and oriented with respect to each other. In this paper we describe a deployment scheme where each of the smart cameras is equipped with a co-located controllable light source which it can use to signal other smart cameras in the vicinity. By analyzing the images that it acquires
over time, each smart camera is able to locate and
identify other nodes in the scene. This arrangement makes
