摘要
在足球运动中,分析比赛需要了解足球场与运动员以及足球之间的位置关系。DLT定标是一种常用的算法,通过改进这种摄像机定标算法,从有限的比赛图像中恢复部分摄像机参数,计算出足球运动员相对于足球场的坐标。实验由两幅静态的图像完成了摄像机定标,通过定标参数和图像对运动员的三维坐标进行了恢复,得到了运动员的三维棍图。
In a football game, the commenting on the match needs to be aware of the position where the players and the soccer are. DLTcalibration arithmetic is improved through which the position of the players can be obtained by deriving several camera parameters fromthe limited competition image. The 3D position of a player is calculated by processing calibration parameters and two static images that result on cameras＇ parameters. Finally the 3D graphics of players is obtained.
