模式识别和图像分析技术在冰壶运动中的应用

An Application of Pattern Recognition and Image Analysis in Curling

冰壶是奥林匹克运动会的正式比赛项目。针对冰壶的形状、色调特征和定位测量要求 ,提出了通过工业 CCD摄像机获取图像 ,经过基于色调的图像分割进行目标识别和粗定位 ,并通过进一步提取边缘和椭圆模板拟合而获得目标精确位置的方法。实验结果表明该方法可以正确识别物体相对于标线 3

Curling is one of the games in Olympics.Based on its characteristics of hue and shape,a method to obtain the accurate position by video image is proposed.First,a RGB24 image is obtained by CCD camera.Second,a hue based segmentation is implemented in its corresponding HSI image in order to get the rough position of the target.Third,gradient based edge detection and an ellipse curve fitting processing are carried out and the accurate position is obtained.In the experiment,3mm difference between the target and the mark can be detected accurately.
