在本文中，我们提出了一种从网球中的多视图视频合成球员视图的新方法。我们的方法分为两个关键技术：虚拟视图合成和玩家视点估计。在前一种技术中，现有方法“视图插值”是一种从两个视点的真实图像合成中间视点的图像的技术，限制两个视点之间的视点位置。为了避免这种限制，我们提出了一种能够自由设置视点位置的新方法。在后者中，视点位置是使用对极几何根据捕获视频中玩家区域的重心计算的。通过将计算出的玩家视点应用于前一种方法，我们可以合成玩家视图图像。实验结果表明，所提出的方法可以成功地提供网球运动员观看的视频。
In this paper, we propose a new method for synthesizing player-view from multiple view videos in tennis. Our method is divided into two key techniques: virtual-view synthesis and player's view-point estimation. In the former technique, the existing method "view interpolation", which is a technique of synthesizing images in an intermediate viewpoint from the real images in two view-points, restricts a viewpoint position between two viewpoints. To avoid this restriction, we propose a new method of the ability to set up a viewpoint position freely. In the latter, viewpoint position is computed from the center of gravity of a player region in captured videos using epipolar geometry. By applying the computed player's viewpoint to the former method, we can synthesize player-view image. Experimental results demonstrate that the proposed method can successfully provide tennis player-view video in tennis.
