On the Hardware/Software Design and Implementation of a High Definition Multiview Video Surveillance System

摘要

This paper proposes a distributed architecture for high definition multiview video surveillance system. It adopts a modular design where single view/stereo intelligent internet protocol (IP)-based video surveillance cameras are connected to a front-end field programmable gate array (FPGA) board(s) which are connected to a back-end local video server through the IP network. The data intensive video analytics (VA) algorithms such as background modeling, connected component labeling and single view object tracking are implemented in the FPGA using an efficient fix-point based architecture. Each back-end video server is equipped with a storage and graphics processing units for supporting high-level VA and other processing algorithms such as video decompression/display, mean depth estimation and consistent labeling. A real-time prototype system was constructed to illustrate the architecture and VA algorithms involved. Satisfactory results were obtained for both publicly available data set and real surveillance video data.
