摘　　要：为实现自动的辅助大学足球教练员判别队员定点射门训练时足球进门时与球门的相对位置,提出一种数字图像自动处理算法。在自然条件和复杂动态背景下,采用1200万像素以上分辨率的普通单摄像头不固定的安装到指定区域内的任意一点进行图像采集。利用图片的平面数据信息先后进行多方案去干扰、辨识,提取面积较大的矩形区域、倾斜校正、剪裁、辨识,并提取颜色花纹不确定的圆形、两图形相对位置判别等步骤,实现球门和足球相对位置的准确判别。该算法对计算机配置要求低。实验和仿真结果表明:该算法可以实现预设功能,误差和时间响应能够满足普通高校实际训练和教学要求,经济有效。A digital image automatic processing algorithm is proposed to realize the automatic auxiliary college football coach to determine the position of the football relative to the goal when the football enters the door.Under the natural condition and complex dynamic background,an ordinary single camera with resolution above 12 million pixels is installed not fixedly at any point in the designated area for image collection.Use the picture of the plane data information,through steps as multiple solutions to remove interference,extract large rectangular rings,tilt correction,tailoring,identification and extraction of uncertain circles of colors and patterns,and the relative position of the two images.Recognit the accurate discrimination of the relative position of goal and football.And the algorithm has low requirements for computer configuration.The experimental and simulation results show that the algorithm can achieve preset function,error and time response can meet the actual training and teaching requirements of ordinary universities,and it is economical and effective.
