英文摘要：

To overcome the shortcomings of traditional moving target tracking method, such as the time difference method, template matching method, background to division method, optical flow method and so on , this paper studies the MeanShift algorithm and extended MeanShift algorithm, and then realizes the moving target tracking procedure based on the extended MeanShift algorithm using Labview. The extended MeanShift algorithm in the application of moving target tracking is verified by the experiments with real-time, practicability, accuracy and stability. The experimental results show that the extended MeanShift algorithm can track the moving target primely, it can track target accurately even when moving targets is partly covered.
