Automatic video production of sports aims at producing an aesthetic broadcast of sporting events. This is an enabler of low-cost solutions for TV-like streaming of sports events. We present a new video system able to automatically produce a smooth and pleasant broadcast of football games using a camera rig composed of three fixed 4K cameras. The system automatically detects and localizes the main action of a football game and frame it, so it yields a professional cameraman-like production of the football event. We compute the actionness of a football game using a ball detector and an occupancy map representation of players based on a saliency map. The action framing is computed through geometrically pitch modeling. The whole video processing pipeline is done in the edge using smartphones and we report a 25 FPS throughput.

体育运动的自动视频制作旨在制作体育赛事的美学广播。这是为类似电视的体育赛事流媒体提供低成本解决方案的推动者。我们展示了一种新的视频系统，该系统能够使用由三个固定 4K 摄像机组成的摄像机装置自动制作流畅、愉快的足球比赛转播。该系统自动检测和定位足球比赛的主要动作并对其进行构图，因此它可以产生专业的摄影师般的足球赛事制作。我们计算动作性使用球检测器和基于显着性地图的球员占用地图表示的足球比赛。动作框架是通过几何音高建模计算的。整个视频处理管道使用智能手机在边缘完成，我们报告了 25 FPS 的吞吐量。
