摘　　要：为了使视觉监控系统具有自主能力,设计了一种基于嵌入式高速DSP处理器Blackfin533的运动目标自动跟踪系统。文中分别介绍了系统的硬件和软件设计。该系统运用差分图像法,通过阈值图像分割来检测运动目标,并采用形心跟踪算法来自动跟踪目标。实验结果表明该系统取得了较好的跟踪效果。In order to make the vision surveillance system to have autonomous function, an automatic-tracking system of motion target based on embedded high-speed DSP processor Blackfin533 was designed. The system's hardware and software design was introduced separately. This system detected motion target using difference image method through threshold image segmentation, then automatically tracked target by using centroid tracking algorithm. The experimental result shows that the system has better performance.
