摘要: 针对排球比赛的复杂场景提出一种排球轨迹追踪方法。利用排球的抛物线运动特性及其在2D场景中的运动分布特点,结合排球固有属性特征获取排球候选对象。采用X轴分布图和Y轴分布图表示排球候选对象的位置,建立排球轨迹方程。用轨迹方程矫正并辅助排球追踪,以确定排球轨迹。实验结果表明,该方法的排球轨迹检测正确率达92.25%。

Abstract: Aiming at the complicated scene of volleyball game, this paper introduces a volleyball trajectory tracking method. By making use of volleyball’s parabolic motion character and its moving distribution features in 2D scene, it gains the volleyball candidate objects according to the natural attributes of volleyballs. By showing the position of volleyball candidate objects in X distribution images axes and Y axes distribution images, it sets up the functions of volleyball trajectory to rectify and assist volleyball tracking. Experimental results show that exact rate of volleyball trajectory detection of this method is 92.25%.

Key words: game rule, object detection, trajectory extraction
