Embedded Intelligent Video Surveillance and Cooperative Tracking System

Nowadays, mobility and flexibility are becoming more and more important in surveillance systems to deal with emergencies and contingencies. In this paper, we design and implement an embedded intelligent video surveillance and cooperative tracing system based on DM6467T. In our system,the ARM core of DM6467T is mainly in charge of getting encoded video data from the Internet, while the DSP core conducts video decoding and intelligent video computing. The video computing consists of three parts: moving objects detecting, moving objects locating and moving object stracking. Specifically, we propose an improved template matching algorithm to solve the global motion compensation problem while reducing the computing complexity. Taking full advantage of the DM6467T's DSP+ARM heterogeneous processors, the embedded system is convenient and flexible to implement and can be widely used in various surveillance environments, especially in occasional and emergent surveillance scenarios.
