实时红外成像跟踪处理器的研究

研究了一种基于DSP FPGA结构的跟踪系统,实现了对红外成像目标的实时跟踪。硬件上以DSP为主控制器件,大规模现场可编程逻辑器件(FPGA)为辅助控制器件;软件算法以经典相关匹配算法为基础,建立了相关置信度评估,模板更新,目标丢失判断以及目标再捕获等准则,有效地提高了跟踪的稳定性和抗干扰能力。试验表明,该系统能够较好的实现复杂背景下目标的稳定跟踪。

Real -time Infrared Imaging Tracking Processor

A system based on DSP FPGA framework for real-time tracking of infrared image targets is introduced in this paper.A DSP acts as the main-control hardware component assisted by FPGA and based on the classical correlation matching algorithm the software algorithm is developed,including rules of creditability evaluation,template update,target missing judgment and reextraction,which enhances stability and anti-jam- ming capability of tracking.Experimental results indicate that the system can perform stable tracking of targets with complicated background.
