【摘要】 在红外跟踪系统中,由于目标太小,常产生阈值设定太高而漏警,阈值设定太低而虚警的问题。文章描述了以FPGA和DSP为核心的信号处理平台,结合多假设跟踪算法提出了一种自适应的阈值选取方法。最后分析了算法在系统中的运行结果,结果表明该算法能快速、可靠地检测出小目标。更多还原

【Abstract】 In IR tracking system,a higher or lower threshold value will result in detecting a point target failed.In the paper,it constructs a signal processing platform using Field Programmable Gate Array(FPGA) and Digital Signal Processor(DSP),and a new adaptive threshold algorithm based on Multiple hypothesis tracking algorithm is proposed.It also analyses the effect in IR tracking system based on this algorithm,and it shows that the algorithm can detect the point target quickly,effectively.更多还原
