摘要

在本文中,我们提出了一种使用多个摄像机跟踪足球运动员的方法。对于跟踪足球运动员来说,遮挡一直是一个大问题,当只用一台相机拍摄场景时,跟踪经常失败。因此,我们使用多视图图像来避免遮挡问题,从而获得球员跟踪的鲁棒性。在我们的方法中,摄像机内操作在每个摄像机中独立执行,用于球员跟踪。如果在相机中没有检测到玩家,则执行相机间操作,并通过相机之间的几何关系来整合所有相机的跟踪信息,该几何关系由基本矩阵表示。然后在每一帧中获得玩家在每个摄像机图像上的位置。实验结果表明,利用多摄像机的优势,可以实现鲁棒的球员跟踪。

Tracking Soccer Player Using Multiple Views
In this paper, we propose a method of tracking a soccer player using multiple cameras. For tracking soccer players, occlusion is always the big problem and tracking is often failed when only a single camera is used to take the scene. Therefore, we use multiple view images for avoiding the occlusion problem, so that we can obtain robustness in player tracking. In our method, inner-camera operation is performed independently in each camera for player tracking. If the player is not detected in the camera, inter-camera operation is performed and tracking information of all cameras are integrated by the geometrical relationship between cameras which is represented by fundamental matrices. Then the location of the player on each camera image is obtained in every frame. Experimental results show that robust player tracking is available by taking advantage of using multiple cameras.
