Dim Target Detection and Tracking System Based on TMS320DM642

摘要

In order to satisfy the real-time realization request of dim target detection and tracking, a dim target detection and tracking system based on TI's high performance digital multimedia DSP chip TMS320DM642 is presented. This system uses local texture analysis method which is very fit for dim target detection in low SNR (signal to noise rate) to realize the detection, then to realize effective tracking, and the program's processing speed and pipelining efficiency is highly boosted by optimizing the software program, so the system has very good software and hardware system structure. Experiments on real infrared image sequences show that the system in this paper can detect and track dim target with 1-3 pixels in clutter background steadily in real-time, at meanwhile, this system can be widely applied to other fields of image processing by reconfiguring the software part of the system. The real-time ability, stability and versatility of the system are proved.
