摘　　要：根据红外弱小目标检测和跟踪的实时性要求,基于中波红外热像仪、双数字信号处理器(DSP)、管理板卡HEPC9,双DSPC6201和双现场可编程阵列(FPGA)搭建了一套实时的红外图像处理系统。同时针对C6201微处理器,成功实现了弱小目标检测与跟踪程序的优化和移植。系统测试表明:该系统实时和有效检测跟踪每秒50帧,每帧320×240,每像素14位的低信噪比复杂序列图像。Towards the problem of real time detecting and tracking in infrared image, a practical system is built based on midwave stareing focal plane infrared sensor, HEPC9 (for double-DSP management), double-DSP C6201 and double-FPGA.The proposed algorithm of detection and tracking is successfully optimized and transplanted to the hardware processor. Processing results with the real image sequences show the system can real-time and effectively detect and track the small moving target in low SNR infrared image sequences with 50 frame persecond, 320*240 perframe, 14 bit perpixel.
