摘要
对篮球飞行轨迹进行图像视频跟踪,可以精准分析篮球的飞行轨迹曲线,从而指导篮球投篮训练。提出基于图像视频序列分析的篮球飞行轨迹跟踪方法。进行篮球飞行轨迹的图像视频序列采集,采用Radon尺度变换方法进行图像的降噪处理,拟合跟踪图像视频序列的灰度像素值特征点,实现飞行轨迹的图像量化分析。最后进行仿真测试,结果表明,采用该方法进行篮球飞行轨迹跟踪的拟合度较高,特征点提取的精度较高,对指导篮球训练具有积极意义。
The video image tracking of the basketball flight path can analyze the curve of the basketball flight path accurate- ly, and guide the basketball shooting training. A basketball flight path tracking method based on video image sequence analysis is put forward. The video image sequence of the basketball flight path is acquired. The Radon scale transform method is adopted to denoise the image. The gray level pixel value feature point of the tracked video image sequence is fitted to realize the image quantitative analysis of the flight path. The simulation test was performed for the flight path. The results show that the method has high fitting degree for tracking the basketball flight path, high extraction precision of the feature point, and positive signifi- cance to guide the basketball training.
