摘　　要：针对视频文件中运动目标检测与跟踪这一问题,提出一种先检测后跟踪的方法.首先利用平均背景法完成对背景模型的更新,从而检测出运动目标,在此基础上利用投影法来投影出运动目标的大小,最后再利用MeanShift算法对运动目标进行跟踪.在跟踪过程中,通过OpenCV编写程序实现对运动目标的检测与跟踪.实验验证,该方法在实现运动目标的精确检测与跟踪的基础上,减少了运算量,提高了跟踪的速度.In order to solve the moving target detecting and tracking in video sequence, the algorithm tracking follow detecting is proposed. First, it updated background model using the averaging background method, and detected the moving target. Then the size of the moving target was acquired by projection method. Finally, it tracked the moving target using the MeanShift tracking algorithm, During the object tracking, it programmed by the OpenCV to achieve the moving target detecting and tracking. The experiments show that the algorithm not only realize the detecting and tracking of the moving target exactly, but also reduce the amount of calculation and improve the tracking efficiency.
