Multi-DSP based Intelligent Visual Surveillance System
An Intelligent Visual Surveillance (IVS) system based on multi SEED-VPM642 platform is proposed in this paper, including design and realization of both the hardware and software platforms. The core chip of the platform is TI multimedia Digital Signal Processor (DSP) TMS320DM642. In the system, DSP acts as a server, waiting for client PC to get connected to the Internet. In DSP, video captured by cameras is processed by algorithms in real time, then encoded, and finally sent to PC. If any event breaks the rules set by users on PC, alarm signal will be sent through the Global System for Mobile Communications (GSM) network. Experimental results show that the system works well in detecting and tracking objects. Meanwhile, PC Graphical User Interface (GUI) supports monitoring 16 video scenes at the same time and controlling Pan/Tilt/Zoom (PTZ) camera, also allows video playing back. In addition, our system supports both Client/Server (C/S) and Browser/Server (B/S) architecture.
