| 摘 要： | 基于ADI公司Blackfin系列DSP BF549数字图像处理芯片,提出了一种在动态背景下对所采集图像中的动态目标进行实时跟踪与显示的嵌入式设计方案。对系统的工作原理、硬件及软件设计三方面进行了介绍。该设计方案充分利用BF549芯片的高性能视频处理能力,采用基于图像配准的运动目标检测方法,首先将采集的4幅相邻帧图像的背景进行配准,之后再利用差分相乘法,实现了动态背景下运动目标的检测,并利用球机对运动目标进行实时跟踪,最后将跟踪结果显示在TFT液晶屏幕上。

| Abstract: | A design scheme of embedded moving target real-time track and detection result display is proposed.The design is under the static background environment and based on Blackfin BF549 produced by Analog Device.The work-ing principle,system hardware and software are introduced.The design adopts inter-frame difference multiplication algo-rithm based on four adjacent images registration to detect the moving target,then use the tracking ball camera to track the moving target at real time,and display the tracking result on the LCD screen. |
