摘要
为了提高篮球运动中的投篮命中率,采用图像分析方法进行投篮视觉校对,提出最优投篮角度的视觉校对方法。首先进行篮球投篮轨迹特征角点提取,然后采用边缘轮廓组合滤波方法进行信息增强,对增强处理后的篮球轨迹角点进行自适应跟踪融合处理,从而实现最优投篮角度的视觉校对。实验结果表明,该方法可以实现最优投篮轨迹跟踪识别,通过视觉回放校对指导篮球投篮动作的校正,提高命中率。
In order to improve the basketball shooting percentage in basketball sport,the image analysis method is used to check the basketball shooting vision.A vision check method of the optimal basketball shooting angle is proposed.The basketball shooting trajectory feature angular points are extracted.The information of the extracted points is enhanced with the edge contourcombined filtering method.The adaptive tracking fusion processing of the enhanced trajectory angular points is performed tocheck the vision of the optimal basketball shooting angle.The experimental results show that the method can track and recognizethe optimal basketball shooting trajectory,guide the check of the basketball shooting action by the vision playback,and improve the basketball hit rate.
