为了从电视图像中创造一个更逼真的足球比赛，我们开发了一个图像合成系统，从球场上的球员的角度生成图像序列。该系统基于摄像机标定理论。该系统首先利用在足球场上绘制的白线的交点确定电视图像的相机参数。然后，它从每张图像中提取玩家，并估计他们在世界坐标系统中的位置。最后，它对处于各自位置的球员应用奔跑动作，并从用户选择的任何球员的视点生成计算机图形动画。该系统在7个序列的电视图像上进行了测试，取得了满意的效果。
To create a more realistic soccer game derived from TV images, we developed an image synthesis system that generates an image sequence from the viewpoint of a player on the field. This system is based on the camera calibration theory. The system first determines the camera parameters of a TV image by using the intersection points of the white lines drawn on the soccer field. It then extracts players from each image and estimates their positons in the world coordinate system. Finally it applies a running motion to the players in their respective positions and generates computer graphics animation from the viewpoint of any player selected by a user. The system was tested over seven sequences of TV images and demonstrated satisfactory results.
