基于图像处理的目标跟踪系统 摘要：介绍了一种基于OpenCV的运动物体跟踪算法，用于实现在背景中检测出运动目标并实施警戒等特定提示的目的。该算法利用背景差分法得到当前帧中的静止的背景模型，并在不断更新的视频图像中检测前景图像，提取出运动目标。简单介绍了必要的函数和数据结构，以及重要的程序板块。实验结果表明，该方法可以较好地实现视频序列中运动目标的检测，具有实时性，并能得到较好的检测结果。相信在安防监督领域有更为广泛的运用。

The target tracking system based on image processing Abstract：It's introducing a kind of moving objects tracking algorithm based on OpenCV,which is used to realize the purpose of detection on moving objects in background and implementing of specific tips for warning.The algorithm gets the static background model in the current frame with the background-finite-difference method, and tests the foreground images in the constantly updated video images ,and extracts the moving targets from them, .In addition, it introduces the necessary functions,data structures and the important program plates. The results we get from the experiment shows that this method can well realize moving targets detection in video sequences, which are defined, and we can get a good test results from it with believing that this method will be more used of in the security supervision areas.
