摘　　要：体育视频运动目标分析跟踪有重要的现实意义,分析了体育视频中运动目标跟踪的难点及采用跟踪需求,对运动目标的跟踪方法进行具体阐释。采用分布式多摄像机拍摄模式分析体育视频,用改进背景消减法对运动目标进行检测,用小波变换法、光流特征提取法、颜色特征提取法分别提取运动目标的纹理、光流和颜色特征,最后采用均值移位跟踪算法和彩色直方图算法相结合的方法确定并分割目标,实现对运动目标的精确跟踪。The analysis and tracking of sports video moving target has important practical significance. It analyzes the difficulty of moving target tracking in sports video and adopts tracking demand, and explains the tracking method of moving target. The distributed multi - camera shooting mode is used to analyze the sports video. The moving target is detected by the improved background subtraction method. The texture, optical flow and color features of the moving target are extracted by wavelet transform, optical flow feature extraction and color feature extraction respectively. Finally, the method of combining the mean shift tracking algorithm and the color histogram algorithm is used to determine and segment the target to achieve accurate tracking of the moving target.
