Abstract

A distributed smart camera network is a collective of vision-capable devices with enough processing power to execute algorithms for collaborative vision tasks. A true 3D sensing network applies to a broad range of applications, and local stereo vision capabilities at each node offer the potential for a particularly robust implementation. A novel spatial calibration method for such a network is presented, which obtains pose estimates suitable for collaborative 3D vision in a distributed fashion using two stages of registration on robust 3D features. The method is initially described in a geometrical sense, then presented in a practical implementation using existing vision and registration algorithms. The method is designed independently of networking details, making only a few basic assumptions about the underlying networkpsilas capabilities. Experiments using both software simulations and physical devices are designed and executed to demonstrate performance.
