我们在橄榄球内部放置了一个小型无线摄像头,以捕捉球在飞行过程中的视角,以增强观众对足球比赛的体验。为此,我们提出了一个强大的视频合成算法,利用快速旋转相机的独特约束,以获得稳定的鸟瞰点的视频剪辑。我们的算法使用一个由粗到细的图像单应性计算技术,逐步注册图像。然后,我们优化了一个能量函数,该函数定义在像素颜色相似性和到图像边界的距离上,以找到最佳的图像接缝来创建全景合成图像。我们的研究结果表明,我们可以生成逼真的视频从相机旋转的速度高达600 RPM。
We place a small wireless camera inside an American football to capture the ball's point-of-view during flight to augment a spectator's experience of the game of football. To this end, we propose a robust video synthesis algorithm that leverages the unique constraints of fast spinning cameras to obtain a stabilized bird's eye point-of-view video clip. Our algorithm uses a coarse-to-fine image homography computation technique to progressively register images. We then optimize an energy function defined over pixel-wise color similarity and distance to image borders, to find optimal image seams to create panoramic composite images. Our results show that we can generate realistic videos from a camera spinning at speeds of up to 600 RPM.
