Study on a Real-Time Image Object Tracking System

A programmable real-time system based on DSP and FPGA for the image object tracking is proposed. The high-performance fixed-point DSP TMS320DM643 as kernel processor is suitable for processing video signal. This paper presents in detail the work flow of the solution, the function and principle of components, such as preprocessing and OSD FPGA, the external memory interface, the transport and control of digital video data stream, the module of multi-voltage power supply and monitoring. The experiments and analysis show that peak-value, poid, and correlation tracking algorithms using gray-scale of video sequence could be implemented on the hardware platform in real time.
