摘　　要：针对现代红外防御探测系统高帧频实时目标检测跟踪处理的要求,介绍了一套自研的便携式红外自动目标检测跟踪系统的工程实现。首先分析该检测跟踪系统总体结构,详细介绍系统组成和功能。针对该系统中实时信息处理的关键技术,在体积和功耗严格受限的条件下提出了一种基于DSP+FPGA的可重构实时信息处理机的结构,系统图像及检测结果通过USB 2.0接口传送至主机。此外,对处理机的硬件结构、DSP软件算法流程、USB驱动程序和固件程序进行了介绍,系统联调实验结果表明该系统具有很好的实时检测跟踪性能。Aiming at the requirement of real- time processing of target detecting and tracking in modern IR defensing and detecting system, this article introduces the design and implementation of a portable IR targets automatic detecting and tracking system developed by ourselves. Firstly it analyzes the overall structure and introduces the composition and function in detail. Secondly aiming at the key technology of real- time processing with the limit of volume and power, the real - time signal processor which is reconfigurable based on DSP＋FPGA is proposed,which send the images and detecting results to the host computer by USB 2.0 interface. Besides, the configuration of the hardware, the implementation of the target detection flow chart in DSP, the driver and the firmware of USB 2.0 are introduced. The experimental result shows that the system can detect and track the target automatically and accurately.
