摘　　要：为更好的对篮球运动轨迹进行分析,提高轨迹分析的准确性,提出一种改进Hough算法,实现对篮球位置的准确定位,以此为后续的篮球运动轨迹分析奠定基础。对此,本文首先采用混合高斯背景建模方法对前景信息进行获取,然后采用数学形态学对图像进行腐蚀处理,最后通过改进Hough算法完成对篮球球心的定位。试验结果表明,本文构建的算法可清晰的显示球心的位置,同时检测时间大大降低。In order to better analyze the basketball trajectory and improve the accuracy of the trajectory analysis,an improved Hough algorithm is proposed to realize the accurate positioning of the basketball position,which lays the foundation for the follow-up analysis of the basketball trajectory.Firstly,the foreground information is acquired by the method of Mixture Gauss Background Modeling,then the image is corroded by mathematical morphology,and finally the basketball center is located by improving Hough algorithm.The experimental results show that the algorithm constructed in this paper can clearly show the position of the spherical center,and the detection time is greatly reduced.
