Distributed collaborative surveillance system based on leader election protocols

摘要

A variety of visual surveillance systems has been developed to satisfy different purposes. However, traditional visual surveillance systems are inflexible and passive, and thus incur significantly high overhead upon recording video information. Therefore, to improve such systems, researchers have been incorporating some special technologies into traditional visual surveillance systems. Doing so makes the advantages of these adopted technologies able to be attached to these systems such that the systems can benefit much from these technologies. In this study, the authors devise a novel visual surveillance system based on a distributed collaborative mechanism among all monitoring cameras. More specifically, the authors utilise the concept of a well-known distributed application, i.e. leader election, to implement this mechanism. Such a mechanism helps a visual surveillance system with more than one monitoring camera automatically and efficiently assign the proper number of cameras to track a particular object. Hence, upon a moderate number of objects entering the monitoring area, the monitoring cameras will be appointed to each object almost evenly.
